Back lighting graphic shapes – Bus Stop girl

Thursday, December 11th, 2008

Backlighting • Graphic shapes • Channel mixer • Cropping

The best way to show graphic shapes is to reduce the scene you are photographing to its most basic and fundamental elements. In this case that reduction process meant removing the colour and producing a level of contrast that would show exactly the lines and curves that caught my eye in the first place. I couldn’t control the light, obviously, and the scene only worked from one angle, but it is the element of back lighting that really helps, even in these overcast conditions, to create a semi-silhouette of the bus stop structure and the waiting woman. So I got lucky.

The backlighting reflects off the road and the pavement, making both brighter than they would be from any other angle. This backlighting has also brought out the pattern of the paving and has emphasised the straight edges between each slab. This creates a mass of lines travelling towards the camera and which also lead the eye back into the picture.

Contrasting shapes
The woman stands out as she is the only element in the scene not made up of straight lines, which makes her come forward as the obvious subject. Even the roof of the shelter, which we know is curved in reality, is represented here by straight and solid edges. The only random shapes are made by the pigeon about to land, but as that is quite hidden it doesn’t take too much away from the subject.

Contrast
Having shot this with low contrast settings in-camera I took the image into the Curves and created enhanced mid-tone contrast to strip out some of the image’s greys. In Levels I enhanced the blacks, and reduced the highlight output to inhibit true whites and to soften the visual effect.

Keeping it level, and cropping
At the time of shooting I was very careful to keep all the uprights absolutely straight and level, as they are an essential part of the picture. If you find yours are not quite straight they will distract the viewer’s attention and make them miss the point of the picture. I know I say it a lot, but keeping uprights completely upright is so important.

The last thing I did to the picture was a crop it to 5x4in proportions. I chose this format as it has a classic feel that introduces a quite formal atmosphere that compliments the neat and rigid linear structure and patterns of the scene.

Choosing the moment
Picking the right moment is especially important in this type of scene, as we want to keep things as simple as possible. With people and cars in the background the scene becomes cluttered and we loose the sense of what the shot is supposed to be about. With all these extra shapes that over lap it becomes difficult to see the woman, the back lit road is blocked and the pavement falls into shade. Even one additional element is enough to spoil the picture and create a distraction, as you can see from the these additional shots shown here.

About the black and white conversion
I converted this image to black and white using the channel mixer tool in Photoshop. I chose to use the green channel as it produces the more moderate contrast of the three available. The red channel showed blown out highlights, as does the blue channel. The green channel is also the sharpest and more detailed, and it displayed the right tonal differences between the coloured elements in the scene to make hedges and the grass verge stand out.

Black and white portraits – blue channel man

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.

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.

Shooting into the light – the baby sitter

Monday, July 21st, 2008

The baby sitter, Warsaw, Damien DemolderThey say you should never shoot towards the sun, but I have never really understood why. It’s true that when you take pictures with the camera facing the sun you get flare – reflections within the lens that reduce contrast – but it only looks the same as the flare we get in our eyes. In that way what you see in the picture is a realistic representation of what we see in real life.

In this scene I loved the way the sun was reflecting off the paving, and the contrast between the lightness of the stones and the darker grass and trees. The sweep and shape of the path’s route creates a dynamic feature that really catches the eye, while the line of the trees – on both sides of the shot – lead us from the foreground right out to the distance. The figure walking towards the camera down the central path gives another point of focus in the middle of the shot. The timing was perfect, and is completely down to luck.

I’d lined up the shot and tried a few variations, which I was half pleased with, but felt there was something missing. Then I spotted this old boy coming along pushing a pram and prayed he’d walk into exactly the right place. Strolling slowly he gave me plenty of chances to try out different compositions, but this was the shot that worked best.

I love the long shadows and that special atmosphere that only winter light delivers. There is some flare in the picture, but it adds a sense of reality. What I like most is that the picture looks just as I remember seeing the scene. Using a wide angle lens allowed me to capture a wide sweep of the scene, and keeping the camera as level and straight as I could means viewers can concentrate on the subject rather the distractions of leaning buildings and a sloping horizon.

I shot in colour, and converted the picture to black and white via channel mixer using only the red channel, and then adjusted the contrast a little. I knew the light reflecting off the paving would fool the camera’s light meter, so I took a spot reading from the grass on the right hand side of the scene.
