Photographer's Note

This shot is a workshop too, when it ends up on page 3 or 4 I'll add the text to the new tips section of the forums.

We all know that sometimes a black and white image has much more impact than colour, but PhotoShop’s desaturate command sometimes disappoints, giving rather flat images, there’s a much better way to do it, and it only takes a couple more seconds to achieve.

What you need to do is choose Layer/New Adjustment Layer/Channel Mixer.
Click OK on the first box that appears, a further box will appear, this is the channel mixer dialogue box.

Tick the monochrome selection box at the bottom. The image will immediately turn black and white, but this is where it gets interesting, try moving the source channel sliders about, initially the red channel is set to 100% and the other two 0%

What you are doing is simulating a shot taken with black and white film, but with a coloured filter in front of the lens, this can dramatically alter the look of the image, when you are happy with the results, click OK, then , Layer/Flatten Image to finalise it.

This picture of a squirrel was changed to black and white, using the above method, I went for maximum blue (100%), and both red and green at 0% to imitate it being shot through a blue filter.

Just a touch of colour was added after flattening the image, and the light fall-off at the corners of the picture was created by making a round gradient alpha mask and lowering the brightness/contrast.
