Using exposure compensation – Walking into the light

Thursday, June 16th, 2011

Walking towards the light, Millenium Bridge, London

Here’s a simple but effective way of making a small subject stand out from the background. Early in the morning, or actually any time that the sun is low in the sky, we get great shafts of light that streak between buildings to carve streets in two. Usually, if we allow the camera to do its own thing, these powerful beams of light will appear white and burnt out in the frame, but if you measure and expose for the beam instead of the scene in general, you can use them to great effect.

In this instance I was looking for a way to pick out a single person in this very busy part of London. Often I will do this by using a very shallow depth of field, or by getting close with a wideangle lens. On this morning though the sun was acting as a spotlight on a stage, so all I had to do was use it.

The camera was set to evaluative metering, which obviously was reading for the whole scene. With no interference from me the exposure chosen worked well for the scene but left the area where the sun was falling as a burnt-out white line. Obviously this wasn’t making an interesting picture, or illustrating what I could see with my eyes. The excitement of the scene was that the sun could pick anyone out who walked through its rays – and that is what I wanted to catch.

I was using a manual focus lens at the time, so set the focus point for the paving right where the sun was shining. I guessed that I would need exposure compensation of about three stops (-2EV) so I set this and took a trial shot. It looked about right. I could have set spot metering and measured that way, but I would have had to have walked over to the spot to fill the spot zone, and a guess, with the chance to make corrections, seemed a better and quicker option.

Once I was happy that the exposure and focus were good, I framed the shot and waited for the right person to come along. This is a popular route for runners, school children and to workers travelling to the office. I didn’t really know what sort of person was going to make the best shot, but I knew that when that person came along it would hit me. I didn’t have to wait long for this chap to pass by and make the scene complete. The face, the pose of the arms and legs and the outfit all work to tell us the story of the moment.

Be prepared – lover’s hideout

Lover's hideout, by Damien Demolder

Try something out. Put your camera in its bag, and put the bag over your shoulder. Now, pretending you are Clint Eastwood in a cowboy movie, see how quickly you can ‘draw’ your camera, including switching it on and squeezing a shot off. Providing the settings are about right for the light levels and light types you are practicing in, it probably takes about four to five seconds. If you need to adjust the ISO to achieve a shutter speed at which you can hand-hold the camera and lens, that ‘draw’ time might extend to ten seconds – depending on how user-friendly your camera’s menu system is. It’s a good job you are pretending to be Clint rather than fighting against him, as you’d never get that shot off.

Whether you are a fan of Mr Eastwood’s movies or not you will have noticed that when the man himself is sliding round the side of the General Store in search of the bad guys he keeps his gun in his hand, safety catch off, so it’s ready to fire. And if you are into street photography and catching ‘the moment’ you need to take a leaf out of his book.

Keep reviewing your settings
The day I shot this picture it was heavily overcast and dark. It was also very cold, so I was wearing those fingerless burglar gloves, so that I would be able to hold the camera in my hands all day and still be able to work the controls. As the day got darker and darker I had been adjusting my ISO settings so that I would be able to maintain a shutter speed of at least 1/30sec – the camera had anti-shake built-in. I had a 28mm lens fitted, which gave me a 42mm equivalent focal length on my APS-C sensor, and I’d got it stuck wide open at f/2 to let in as much light as I could get.

Rounding the corner of a building I came across these two lovers hiding away from the world to share an few intimate moments together. Before I knew it I had the camera at my eye and was focusing the manual lens. As the shutter fired she just had time to look a little bit sheepish, and he just had time to hide his head behind hers.

Ready to shoot
I took one shot, smiled at them as they laughed at being caught, and then I walked on. It all took about two seconds, and I got the shot because the camera was there in my hand whirring and straining at the leash to take a picture. Had it been curled up snoozing in my camera bag this incident would have just been another one of those occasions when the shot got away. I wouldn’t even have drawn, as I’d have known immediately that as soon as I’d started getting the camera out the dynamics of the picture would have changed and the moment would be passed.

Composition in an instant
With practice I’ve learnt not only to get the subject in the frame in a split second but also to ensure I have a composition. I never know what the next composition is going to be, but I do know that even the sort of picture that is grabbed in a fraction of second needs to respect the viewer and respect the laws of image construction. I managed to keep the camera straight so those blocks wouldn’t create a distraction by sloping off to one side, and I positioned the couple at the bottom of a tall frame to prevent a centre-weighted or top heavy composition. I had to keep her feet in too, and his, and frame the pair of them in their alcove by showing some wall either side so the viewer can understand they were hiding away.

Wide aperture
The wide aperture has combined with the overcast sky to create an almost dreamlike softness that works well in the sooty black and white, blue/green channel conversion. There is romance in the softness that adds a fairy tale quality.

Black and white portraits – blue channel man

Monday, October 20th, 2008

Using filtration in male portraiture • channel mixture conversions • shooting in colour for a black and white result

Black and white blue Channel conversion male portrait We automatically think about using channel filtration to create black and white images when we are shooting landscapes, because we are all used to the idea of fitting filters for this type of subject. The reference pictures that stick in the mind that demonstrate what filters do to monochrome images – the deep black skies and fluffy clouds of the red filter – are generally landscapes in which we can see how blues darken and green grass lightens. In fact, you probably wouldn’t shoot a black and white landscape without thinking about filtration.

We don’t associate lens filters with portraiture in the same way, unless warming or adjusting a colour picture, but sometimes red filters are used to reduce the effects of skin blemishes. With this in mind when converting a colour portrait image to black and white I often use a red channel bias in Channel Mixer (Image>adjustments>channel mixer) to lighten the redness of spots, skin patches and veins close to the skin surface. This looks great for women, as it can leave a flattering facial glow as well. But it really doesn’t look macho enough for portraits of men.


A portrait converted to black and white via the red, green and blue channelsI have found the channel that delivers the more manly effect is the blue channel. It adds depth to the skin and presents a more tanned, or weathered, look (I know, but you can still see it in black and white!). The blue channel makes men look stronger and more heroic, which I think is what most men prefer. And the deeper and more complex shades of this kind of conversion provide the ideal base for adding a colour tone too. There is so much more grey in black and white images converted using the blue channel that toning and staining colours have much more impact.

By Damien Demolder If you find a blue channel conversion produces too strong a result remember that you don’t have to use it on its own. My favourite channel of all is the green channel, as it has lower contrast and better sharpness than red or blue, and I like to mix it in with the others to rein in any over-blown effects. Try mixing 50% green and 50% blue for a more restrained image.

Obviously to make use of these effects and options you need to be shooting your portraits in colour. I find that shooting everything in colour gives me the most flexibility, so I shoot in colour even when I know I will only want a black and white final result.
