Photographing horses in Menorca

One of the great photo opportunities we often enjoy on our photography holidays in Menorca is the chance to photograph horses – very special horses. We spend some time at the trotting races, where we are welcomed to visit the stables and photograph the race preparations. We use the races themselves as exercises in panning technique and I teach everyone the art of ‘following through’ with the camera as the subjects race past – very much like the ‘follow though’ in a golf swing. This has produced some fantastic shots… you may remember Maria Falconer’s action-packed picture I posted some time ago. Click here.

Now most photographers need a fair bit of help and practice to perfect the panning technique, but on our latest holiday we had one snapper, George Greenhill, who amazed us all with his panning accuracy. Even when the horses were racing past us a top speed, the horses and riders were always perfectly framed in every picture he took. It was uncanny just how easy he found it to get great panned action pictures.

I expected that George had done this before, so I asked him where he had learned the technique.

“In the army,” said George, “I was a machine gunner”.

I would hate to be on the receiving end of Georges sure-fire technique.

Menorca is famous for, among other thing, its dancing horses. These jet black beauties are taught the most extraordinary dressage routines and to rear up on their hind legs. The horses are a great attraction at fiestas and weddings. Our photography group was lucky enough to witness a wedding party at our hotel at which the rearing horses were to be a great attraction.

The party was held at night in the street outside the Hotel, so the light was just about as difficult as it could possibly be. But just look at these two photographs produced by Ken Terry – fantastic pictures that have captured the wonderful atmosphere of the event. Ken used his new Canon EOS-1D Mk111. He pushed the ISO right up to 3200 and was able to shoot at 1/30sec at f3.2

There are more pictures and stories from Menorca to come.

These holidays have proved a great success and if you’d like to join us next year please let me know as soon as possible. I’ll be putting the dates and costs up on the photoactive website very soon.

Canon Ixus 960IS


My little Canon Ixus 700 has expired. I suppose it was my own fault, I put it in its soft case and attached it to my belt before donning old waterproof clothes and tackling a heavy outdoor job in torrential rain. After a couple of hours it was just as wet inside the waterproofs as it was out. My little camera drowned quietly in bed. The lens steamed up and refuses to come out to play, and it now raises only a pathetic bleat when I switch it on. I’ve tried taking out the battery and drying the camera out it in the airing cupboard, but to no avail.

Once I certified it as dead I immediately set about finding a replacement. It had to be just about the same size and weight as the old Ixus 700, but higher on pixels. Eventually I chose another Ixus – the 960IS.

It has been on my belt now for just over a couple of weeks and I am, so far delighted with the camera.

I really got chance to try it out the other day when I visited a Bloody Island in Mahon Harbour, on Menorca. I was there to explore new locations for my photography holidays in Menorca.

The camera behaved beautifully and did everything I could have wished. Even interior shots in very difficult light conditions proved no problem with judicious adjustment of the exposure compensation control in the ‘M’ Manual mode. This ‘M’ is not a true manual mode as it does not enable you to change the aperture or shutter speeds – it’s a sort of half-way house. But if you can work within the limitations, it is perfectly adequate for many situations.

One of the secrets of getting outstanding quality with these small cameras is to keep the ISO as low as possible. When the ISO is raised to the maximum 1600 on this Ixus 960IS, the results are, to be kind – noisy. However, there are some situations when in order to get a picture with any sort of atmosphere (avoiding flash), that noise just might be a price worth paying.

So far I’m pleased with the Ixus 960IS and its 12 Mega pixels are providing me with some excellent quality images.

The camera was bought from Amazon for £222. Postage free.

The IS (Image stabilisation) has worked well – this shot was hand-held at 1/4sec. ISO200 and it is very sharp. I ave desaturated the colour in Photoshop because I think bw adds to the interest of the picture

The Ixus 960IS has coped very well with the wide range of light strengths in this situation. I simply set the Exposure Compensation value to minus 1.5 to achieve even results and not ‘burn out’ the stronger light through the doorway

Low ISO speed



I've just arrived back in my home port of Kirkcudbright aboard my boat Moonshadow. Almost the first thing I did was reach for my little Canon G9 and take a picture. It was late afternoon and the light had that special brilliance. It was shining full belt onto the scallop fishing boats standing high and dry in the mud alongside the harbour wall at low water. The resulting picture would have been better if the water had been totally smooth in order to give perfect reflections. Unfortunately there was just a hint of a breeze and this has ruffled the surface of the water a little, breaking the reflections.

But never mind, I like the deep colours that have been accentuated by the front light and the contrast of the greens, blue and rusty reds.

Like I've said before - boating and photography are the perfect combination.

I set the G9 on aperture priority at f7.1. This gave me a shutter speed of 1/200sec at ISO 80 - remember, it's always best to use the slowest ISO possible for best quality. There was plenty of light, so ISO 80 was ideal. I used centre-weighted metering mode. The exposure compensation was set to minus 1/3 and the white balance on AWB. I was zoomed in to give me an equivalent focal length of around 85mm.

Photography student's success


Photograph by Margaret Laurie
It’s always a huge pleasure for me when I hear that I have been able to inspire someone and set them on the right track.

Margaret came to one of my weekend workshops here in Kirkcudbright in SW Scotland earlier this year. The other day she emailed me hardly able to contain here excitement because one of her photographs had been accepted for publication in the Scotland on Sunday newspaper. This is what Margaret said:

“You helped a lot to inspire me to take more photos, and give me some confidence to send my photos into the paper.

“This photo was taken a couple of Fridays ago at the beginning of May. We live in Ferryhill, Aberdeen and I'd woken early with the sun streaming in through the window, and out of the window saw this fantastic sunrise. I went across the road and that was the view from our street at 5.30am! I took loads of photos while my husband, and daughters were tucked up snugly in bed. The view looks over the rooftops towards the River Dee as it flows under Victoria Road bridge to the harbour then out to sea. The smoke on the right is from an offshore supply vessel. The cranes are all at the docks and the tiny dots are notorious Aberdeen seagulls! I loved the way the cranes and the aerials were leaning towards each other.

“My camera is a Nikon D80, exposure set on manual at 1/1600sec, f7.1, ISO 200, WB set on ‘Cloudy’. The focal length was 112mm.

“The weekend workshop in Kirkcudbright with yourself gave me the oomph to do something with my photos. As you can see I now use my camera in manual, and that's pretty much 99% of the time, and experiment with the white balance, and still take B & W.”

Very well done, Margaret. You have every right to be very proud of yourself. I can still remember the buzz I got from my first publication – and that’s a very long time ago.

Might I have done things differently? Well, perhaps I might have used a slightly different exposure setting, but Margaret has achieved such a beautiful result that any alterations would only amount to fine tweaking.

By using the ‘Cloudy’ White Balance (WB) setting, Margaret has added to the yellow/orange glow from the early morning sun. Great idea. With so much light available, I might have used a ISO 100 for maximum image quality, stopped the aperture down for extra depth of field (this part depends on what Margaret was wanting to capture; maybe she wanted limited depth of field), and used a slower shutter speed. This would have given an exposure of roughly 1/500sec at f11. 1/500sec should be quite fast enough to eliminate camera shake when using a lens with a focal length of 112mm – which on the Nikon D80 is equivalent to about 180mm.

Keep ‘em coming, Margaret. Very well done!

How to photograph moving water - part 1

I had a great day yesterday with Yvonne and Phil who came all the way up from London for a day’s tuition here in Scotland. We spent most of the morning going through some basics on their cameras – with Yvonne keen to understand more about white balance and how to use the manual exposure mode on her Nikon D40.

The weather was good and after lunch we had the choice of either photographing one of the many coves just along the coast, or another of my favourite locations – a beautiful and delicately intricate waterfall that drops out of the Galloway hills not far from my base here in Kirkcudbright.

As Yvonne was keen to try out her skills with moving water – we donned our wellie boots and headed to the waterfall.

You can hear the roar of the waterfall well before I can see it. It’s very well hidden – a real fairy dell. The water drops about 40 feet down a sheer face, it’s stream splitting into several channels which tumble over blackened, mossy rocks. The fall was once used for industrial purposes, and some cast iron pipes still mar the pristine quality of the scene. These can be used as subjects in their own right, or, with careful framing be cut out altogether.

I suggested a simple shooting plan to give the shoot a sense of purpose. We did not rush in to get shots of the water right away, but stood well back and took a good look at the whole scene before me. There is no need to rush in these situations. Waterfalls do not run away, nothing is going to change except the light, and on an overcast day that is unlikely to change much, so take your time and consider each shot. I prefer an overcast day because it helps reduces contrast between the white water and black rock, and if the sun does shine through the trees it can soon create over-exposed hot spots.

We started by taking pictures that included lots of foreground. The green mosses made a startling foreground, so too did the branches of the dead trees.

A good solid tripod is essential if, like me, you prefer to create that mystical, fairy-like, movement in the falling water. You need very slow shutter speeds to do that, about 1sec for maximum effect with a small waterfall, and here overcast weather helps again. The less daylight there is, the slower the shutter speed you will be able to use.

In my DVd on Light and Composition (available from my website), I showed you how to look at the world in rectangles, and introduced you to an imaginary ‘Rectangle Monkey’ who always helps you think and see in rectangles – that’s the way the camera sees. Photographing a waterfall like this is a good time to adopt that way of thinking, because the actually face of the waterfall as it drops down the cliff is really quite two-dimensional, and it is a simple matter to divide the waterfall up into interesting rectangles – starting with the overall view and then framing different interesting areas in both horizontal and vertical rectangles.

CORRECT EXPOSURE
To find the exposure using Manual (M) exposure mode is simple. Knowing I need a slow shutter speed, I just set a very small aperture, f22 and point the camera at the subject (I prefer centre-weighted metering for this type of subject). Then I slow the shutter speed down until the exposure scale in the viewfinder tells me I have the correct exposure. At ISO 100 this gave me a shutter speed of around 1sec; perfect for the moving water effect I was looking for. You do not need fast ISO settings when the camera is on a tripod and you want to use a slow shutter speed… keep it low for best results and better quality.

The pictures here were taken by me on a previous visit to the waterfall – yesterday, I was far too busy helping Yvonne and Phil to get their photographs.

Lower photograph of the waterfall
I started with a simple wide angle shot of the scene, taking in lots of that wonderful green moss in the foreground with the waterfall away in the distance. One of the less appealing aspects of this view can be seen – the end of an old water pipe, just off centre in the picture. There was no way of avoiding this from this angle. A couple of clicks with the cloning tool in Photoshop will soon sort it.
Top photograph
I used the rushing water in the stream beneath the fall to make a lively, moving foreground that injected a real feeling of depth – the third dimension – to the composition. With the wide-angle lens I was able to stand right in the middle of the stream. Here’s when those wellie boots really come in handy
Also pictured above are Yvonne and Phil, my students for the day - they came up from London for their photography tuition
In part 2 I'll explain more about composition - and white balance

Photographing live gigs - part 2


I arrived at the theatre early, well before the start of the show so that I could check out shooting positions and angles. The stage had very limited access to the wings and as the best shots are often taken from the side of the stage, this would make things quite difficult.

The only way to get into this position would be from the front of the stage, so the band had to be happy for me to move up there between songs. Access to the back of the stage, where I could shoot from behind the band, was easy and I checked out all my routes from one position to another while all the house lights were on. I had put a small torch in my pocket so that I would not be stumbling around in the dark when I went back stage during the performance – it would be very dark there then.

I even managed to gain access to a small lighting gantry above the audience from where I could use a telephoto lens for frontal close-ups of the band. During the show, I dodged from one position to the next, and often back again.

As I was on the move and adapting to the different light conditions and positions of the performers, I left my bulky camera bag safely locked in a dressing room and operated with two camera bodies and two lenses.

With the stage lights constantly changing intensity direction and colours, you may find it useful to use the Aperture Value (AV) exposure mode. Remember, this is more correctly called the Aperture Priority (AP) mode. Just set a wide aperture and let the camera decide on the shutter speed. However, I prefer to use the basic M (Manual) mode whenever possible, so that I can change the exposure myself as the lights change. It is also more reliable if shooting directly into bright stage spots – a situation that can confuse any automatic metering mode.

ISO
I set my ISO to 800 with the certain knowledge that I would need the fastest shutter speed possible to stop any action. This would result is some loss of quality, but that was a price worth paying.

EXPOSURES
Most of the shots were taken at between 1/60sec and 1/125sec at f2.8 or f4. Of course these shutter speeds are pretty slow for stopping action, and there were some failures when I pressed the button as the subjects moved, so it was important to take lots of pictures so that these could be discarded. The camera’s LCD illuminator is invaluable when checking settings in the dark in the dark.

WHITE BALANCE
You will never win completely when the stage lights are changing from bright blue to deep red. I simply set AWB (Auto White Balance) and let it happen. Any adjustments I made later in Photoshop.

LENSES
The most useful lens proved to be the 17-35mm f2.8. With this I could get really close from the side of the stage and include the stage lighting in the shot for dramatic effect. For the long shots from the lighting gantry I used a 70-200mm f2.8 zoom. I don’t often bother with lens hoods, but in these conditions, with lights shining into the lens at an angle, I made sure I had a hood fitted to avoid flare

Top photograph
Doug Carroll may not be as famous as Mark Knopler, but he is one of the most gifted guitar players in the UK. I wanted to get a picture that really summed up his total immersion in his music when he played solo. I liked his natural pose with the spotlights shining down on him through the stage smoke. Stage lighting is mostly from front and back of the performers, so if you are photographing a band from the wings you will not be shooting directly into the light

Lower photograph
From the lighting gantry just above the audience I was able to use a telephoto lens and get reasonable close-up shots of the band. The light behind Mary was flashing on and off and changing colour so there was an element of luck involved in getting a good facial expression with the right light backlight





TIP
Earplugs are essential for photographers working directly in front of a powerful sound system. It’s LOUD. Over the years, I've covered dozens of rock bands' live gigs - from the Rolling Stone’s, Rod Stewart, Freddie Mercury. I hate to admit this, but I've covered The Beatles as well – and my hearing has never been the same.

Aperture Value

Carl posted a comment yesterday about Ken Terry's beautiful wildlife pictures.

Ken said that he used ISO 1000 and an aperture of f5.0 in AV mode as the light was changing so quickly. Sometimes the shutter speed was 1/500 and sometimes 1/4000.

Carl commented:
...really enjoyed this. But trying to work out what AV is, in relation to rapidly changing light?

'AV' - Aperture Value - is an automatic exposure mode in which you set the aperture you want and the camera decides on the correct shutter speed to match it. This can be very useful in rapidly changing light conditions like those Ken experienced when he was photographing the red kites and the red squirrels. In these conditions it can be difficult, if not impossible, to constantly adjust the exposure manually. In other words, you just cannot keep up with the fast changing light levels by correcting the exposure yourself in the Manual ('M') mode. When shooting a fast-moving subject like a bird in flight, operating the camera quickly is vitally important, so setting the exposure mode to an automatic setting can be a boon and one less thing to bother about.

So in Ken's case, he set f5.0 in 'AV' mode. When the sun went behind cloud and the light level dropped, the camera chose a shutter speed 1/500sec. When the sun came out and light level went up, the camera chose a shutter speed of 1/4000sec.

Some time ago I posted a photograph of Freddie Mercury. Click the link below. I used 'AV' exposure mode for this because the stage lights in the studio where the photograph was taken were constantly going on and off, with light levels going up and down. It would have been impossible to keep up with the exposure manually in 'M' mode, so I set something like f2.8 in 'AV' mode and let the camera sort out the shutter speed.

Just one tip here... Aperture Value (AV) used to me known as Aperture Priority (AP), far more sensible and descriptive. Until some fool decided to change it.

Wildlife photography

Ken Terry, one of my regular students for some years - and now a good friend - wanted to tackle some wildlife photography before he spent the weekend with my group learning more about portraiture in the comfort of the Cally Palace Hotel.

Ken owns some pretty neat kit and the three wonderful photographs here show that he really knows how to handle it.





I arranged for him to spend a day with Wildlife Ranger Keith Kirk, who knows the area and its wildlife extremely well. Keith took Ken to a secret location to photograph red squirrels and then, despite the cold and rain in the afternoon, Ken got an opportunity to photograph the spectacular red kites, which have been part of a successful re-introduction program here in SW Scotland.




Ken captured some great shots of both the squirrels and the red Kites, and I thank him for permission to post them on the blog. Wonderful photographs Ken. Very well done.



Equipment used: Canon 1D MkIII, Canon 500 mm LIS f4 lens mounted on a Manfrotto 055PROB tripod fitted with a Wimberley version II head. Ken used ISO 1000 and AV as the light was changing so quickly that sometimes it was 1/500 and sometimes 1/4000. It was windy and raining, but the cloud thickness varied.

This is how Ken set up the camera for each shot...


The top picture of the red kite:
AV, f5.0, 1/4000 sec, ISO 1000, Servo AF.

Lower picture of the red kite with its talons in the other bird's tail feathers:

How to take flash photographs – part 4


Over the last three post, I’ve demonstrated just a few of the ways you can create beautiful, soft, directional light with your flash gun attached to your camera. I hope by now you are realising that a flash really is a superbly versatile and portable source of light. When you have the facility to separate that flash gun from your camera, things get even better. Then you can really put light exactly where you want it.

For the photojournalist, a small portable flash is absolutely essential. Without it, he, or she, could not hope to get professional standard photographs in difficult, remote and often poorly lit locations. I have often chosen deliberately to photograph my subjects in what might be described as ‘difficult’ light conditions, and the reason for this is simple – those difficult light conditions can produce highly atmospheric photographs.

Take a glance at the photograph of the man sitting astride the old butcher’s bicycle. This was a wonderful story about a man called Cor Ellen – he is a professional beachcomber on the Dutch Friesian island of Texel in the North Sea. I was commissioned to photograph him for an article for ‘You’, the Mail on Sunday Magazine in UK. I took a great many photographs of Cor – in his home, working on the beach, with his collection of extraordinary things found washed up on the shore. But I wanted an atmospheric shot of Cor on the old bicycle he used to get around the island. I also wanted to show the atmosphere of this remote, wild and windswept place – where better than on the shore beneath the lighthouse.

To add atmosphere, I chose to wait until late afternoon when the light was fading. The camera was put on a tripod. I took a light reading of the cloudy part of the sky. At ISO100, that gave me 1/15sec at f11. The flash was held in my hand as far away from the camera as possible to my right hand side. It was connected to the camera by a long cable (synch lead). I timed the flashes of the lighthouse and pressed the shutter just before it shone.

The flash has fired and lit Cor and the bicycle, but the shutter has remained open – gathering the light from the sky and the lighthouse. A very similar technique to that I described in my article about photographing sparks.

TIP FOR TODAY
Try to avoid those ‘curly’ flash cables – the springy ones like those on a telephone handset. They are a menace because the temptation is to stretch them just a little more, and a little more, to get the flash just that little bit further away from the camera. Then BANG! the tripod is pulled over. It happens so suddenly you will be unable to stop it. Better – if you can - to use a long, simple synch lead with no spring or curls in it. Then you will always know how far it can be pulled.

Cordless infra-red devices are often unreliable in adverse outdoor conditions.

Photographing wildlife


Wildlife photography is a subject that has always interested me, but somehow I have never had the time to learn enough about it. Mostly because I have been too busy earning my living in other branches of photography - in the newspaper, magazine and commercial worlds.

To succeed professionally in wildlife photography you must be not only knowledgeable about your chosen subjects and their habits and habitats, you must also be totally committed. That can often mean sitting huddled up in a hide for hours, sometimes days, or even weeks at a time in order to get that unique shot. Very few photographers possess that level of patience – and I am certainly not among them.

There is, however, an aspect of wildlife photography that is still open to photographers like me. It’s a bit like street photography in that it calls for good anticipation, camera craft and fast reactions, and like street photography, it’s can be done while you are on the move. So there’s no need to be cooped up in a hide. You will also find that some of the old tricks used when photographing people in street photography come in very handy.

The technique involves capturing photographs of wild creatures within, and as part of, their own environment I suppose you might turn the idea on its head and say it is a type of landscape photography with animals in it. It can produce some very beautiful photographs, and they will not lack a powerful focal point. Now I know that a real wildlife photographer should be able to do this AND have the ability to sit in a hide, but I’ve already confessed to my shortcomings in that direction. If you feel the same, it might be worth a try.

As an example I have posted the picture of the stag in the forest.

I was walking along with the forest ranger just after dawn. As we approached a clearing in the trees he mentioned that he'd often seen deer cross this open space. That was all the warning I needed to be prepared. Sure enough as we looked across the clearing a stag appeared moving very quickly and with no obvious intention of stopping. Now its an old press photographers trick to shout out loud in a situation like this. You’ve got nothing to lose and there’s always a chance that the subject might just turn to look where the shout came from. Much to the ranger’s surprise, I yelled ‘STOP!’.

The stag stopped mid-stride and looked in my direction just long enough to get the picture. You see – street photography in the forest.


The photograph was taken on a 300mm lens. 1/500sec at f3.5, ISO 800. The centre of the image has been enlarged considerably.

Photographing Christmas lights

Following our festive theme, here’s a picture of one of those houses festooned with OTT Christmas decorations. Well, you’ve got to take a few photographs, haven’t you?
Once again, the old methods work best in these situations…

Find your best angle.
Get the camera on a good firm tripod.

ISO down to 100.
Aperture stopped down to f11.
Long exposure.

Again, I just used the ‘Bulb’ setting on the camera, opened the shutter for a couple of seconds or so. Checked to see the image was okay, and moved on to the next shot. Keep it simple. It's always best.

What do you do with your White Balance (WB) setting for pictures like this?
Take it easy, that’s what. In this case I stuck it on Auto White Balance (AWB). Doesn’t seem a thousand miles out to me.

TODAY’S TIP
Try to take these pictures just before it goes completely dark. The perfect time is when there is still a touch of colour in the sky.


Have a wonderful Christmas everyone, and thanks for visiting my new blog. I hope you are enjoying it and finding it useful. Please do post your questions and responses.

Photographing Christmas

Okay, let’s get a bit festive and look at how to produce a couple of simple, atmospheric pictures this Christmas.

I put the camera on a tripod. A flash unit was hidden away on the fireplace behind the couple. I didn’t bother setting up flash synch cables or infra-red gizmos. I just got the young chap to fire the flash with his spare hand when I had the shutter open.
I used the ‘Bulb’ setting on the camera and fired the shutter with a cable release – the simple, sensible type that screws into the shutter button. This is the type that you can no longer use because the camera manufacturers have stopped putting the screw thread in the shutter button. Clever – now you have to buy expensive electronic release cable or silly remote controls (have you ever tried using one of those things outdoors in the wet on a bitterly cold night?). Ggrrrr!
I set the aperture to f11. ISO 100 was used. The shutter speed would have been around 2 seconds.

It is a big mistake to try and use wide apertures with this type of shot. Those small Christmas tree lights can often appear as fuzzy little blobs at wide apertures. The magic starts at f11 – just look at the sparkle around the candle on the mantle piece. You do not need star filters to get this – just stop down and use a slower shutter speed.

Depth of Field 2


In my last post I showed you a landscape photograph I took with a very wide aperture in order to limit the depth of field. Also contributing to this limited depth of field was the use of an 85mm lens. Normally, the longer the focal length of a lens the less depth of field it will give. So using a wide aperture with an 85mm lens is guaranteed to limit it and throw much of the scene out of focus. It is a technique that must be used with great care in landscapes. It can look dreadful. Usually it is used to isolate a particular part of the scene. In the case of that picture taken in Thassos, it was used to give an abstract feel to the shot.

It is far more common to aim for the maximum depth of field when taking landscape photographs. That means smaller apertures – f16 or less.

A wide angle lens is a favourite for landscape photographers because it has inherently tremendous depth of field. It also has and the ability to exaggerate the perceived perspective, which has the effect of creating the illusion of depth within a two dimensional image.

In the picture of the old wooden wreck above, I wanted the absolute maximum depth of field, so I have used a wide-angle lens, stopped the aperture right down to f22 and used a shutter speed of 1/4sec. The camera was, of course, put on a tripod, so I was able to use ISO 100 in order to get maximum quality.

How to photograph sparks - Part 2


Exposure for this picture was simple. I just fixed a cable release to the camera, put it on a good firm tripod, set the aperture to f11 and the shutter speed to ‘Bulb’. There’s no point in trying to take a correct light reading because when the sparks start to fly it will be irrelevant. I set ISO 100.

When my subject was ready and producing sparks, I just pressed the button for about 1sec. You will need slow shutter speeds of at least 1/2sec in order to capture the full trail line of a spark – not just the dot of the spark itself. If you use a faster shutter speed you will just capture a series of frozen dots or very short spark trails. This is not in the least effective. Of course, you could use fixed shutter speeds rather than using the ‘Bulb’ setting, it’s just that I prefer my way. I like to ‘gather’ the sparks as they fall and spread. Then close the shutter when I think I have gathered enough.

I set the ISO at 100 because it is not necessary to set a fast ISO when you are using slow exposures and the camera is on a tripod. Remember - the slower ISO the better the quality and sharpness of your image.

Why f11? Because experience tells me that at ISO 100 sparks from a welder’s torch are just about right at f11. For sparks from a disc cutter or grinder, f8 is often best because they are not so bright. Experiment for yourself and see which you prefer.

Unlike the picture in Part 1, there was absolutely no ambient light for this picture. The workshop was completely black This time there is no light on top of the man’s head – his face is lit solely by the glow of the cutting torch and the sparks. In this darkness I could have left the shutter open as long as I wished – provided the subject kept his head still.

TIP… your auto focus will probably not work with this type of subject. Turn it off and set the focus manually.

Next, in Part 3, I’ll explain the ‘bulb’ setting and tell you how to add some flash

How to photograph night events. Part 2

It is sometimes possible to mix and match some of the three methods I mentioned in Part 1 with good results. For instance, you might use flash with a slow shutter speed. The duration of the flash is very short indeed and will freeze any action or movement. The slow shutter speed, however (maybe around 1/30sec or less), will cause the shutter to remain open long enough to capture some of the natural light. Any moving subject lit by this light will appear blurred. This creates a sort of double exposure – one for the flash and one for the available light. It is a technique that can prove highly effective and, if done properly, will inject a powerful sense of movement into the picture.

This was the first picture I took as darkness fell, the action really began. I upped the ISO to 400 and used flash for this picture. I set the shutter speed to 1/30sec and the aperture to f8. This combination has nicely balanced the flash with what little daylight remains in the sky. Had I used a faster shutter speed – say 1/125sec, the sky would have become almost black and the flash would have dominated. Notice how the reflective sign on the very left of the pictures has bounced the light of the flash back again. Beware of this if street signs are in your picture. This time it can be easily cropped off or cloned out.

A little bit of pre-planning can really pay dividends when covering a street event. You may have to decide between finding one good vantage point (see Part 1) from which you can photograph the entire event, or moving around the scene to shoot pictures of the action.

In the photograph on the right you can see that night has fallen. I have used a very slow shutter speed, 1/8sec with flash set to Rear Sync (sometimes called Rear Curtain). This fires the flash at the END of the exposure and creates trails behind any object in the image that moves while the shutter is open before the flash has fired. This can be an effective way of creating the sense of movement within your picture. Experiment - it's fun.

How to photograph night events. Part 1

Outdoor events after dark, present one of the most challenging of assignments; and coping with the light – or lack of it – is at the top of the list of problems you'll face.

The photograph here is of the Kirkudbright Tattoo. A wonderful event of Scottish pipers, marching and music. The shot was planned some days before the event. I secured the use of an upstairs window overlooking the street where the action would take place. From this vantage point I could see everything that happened below and had the backdrop of the castle. The camera was mounted on a heavy tripod which extended out of the window. The ISO was pushed up to 800 and an exposure of 1/8sec at f4 was used. With such a slow shutter speed it was inevitable that there would be some movement in the marching pipers, but as they are marching almost directly towards the camera, this is hardly noticeable. The important aim was to capture the atmosphere and splendour of an outdoor night event in the street.

There are broadly three methods of dealing with the difficulties that low light levels present.

1
Put your camera on a tripod and use a slow shutter speed. You will not need to bother about using a fast ISO, and you will be free to use a smaller aperture with its greater depth of field to get more of the scene in focus. Good, you should have a sharp picture of the overall scene - the buildings and surroundings, and that slow ISO will give you fine quality. But hang on, that’s okay if nothing within the scene moves. If it does, your long exposure may render it as a blur.
2
Whack up the ISO as high as possible, maybe ISO 1600, and use the fastest possible shutter speed to freeze the action. Bearing in mind the low light conditions, you may also have to use a wide aperture to achieve this fast shutter speed, this means you will have less depth of field, and the image will be of poorer quality due to the faster ISO. It’s all a compromise, really. However, this method can achieve some wonderfully atmospheric pictures using what little natural light is available. It's a useful technique.

3
Use eletronic flash. This can freeze any action, but the downside is that it is likely to eradicate any atmosphere with its harsh, ‘press photo’ results… and remember - when shooting with flash outside at night any distant background may become totally black because the light of the flash will not carry that far.

In part 2… I'll show you how to combine some of these methods

Capturing action photographs


I’ve talked about how to shoot action with fast and slow shutter speeds, and demonstrated with two pictures of the horse trotting races. That evening, my group of students and I also spent time looking around the stables between races. This was all part of my plan to keep everyone ‘visually aware’. I did not want them to get fixated on one aspect of the event, but to explore their subject thoroughly.

I spotted the horse tethered to a short chain. He obviously wanted to see inside the stable door and kept stretching as far as possible. I wanted to see the top of his head because I thought it created such a beautiful and unusual angle. Especially as his mane dangled down and the combination of colours was so good. The horse's movements were very quick indeed – just snatches of action. They had to be anticipated, so the only place for the camera was firmly fixed to my eye.

That may sound obvious, but it is amazing how many photographers lower their cameras between shots and raise it again when they think the action is happening – don’t do it! The camera belongs to the eye. It is the only place if you want to capture instant action.

I waited several minutes for this picture, but feel I was well rewarded for my patience.

The light was fading, but I kept the ISO down to 200 for reasonable quality.
