If you're thinking of entering a black and white image into this year's Wilderness Photographer of the Year, presented by Mountain Designs there are a few things you need to consider before you take the shot
Shoot in Colour
Shoot in colour and do your conversion to b&w later on your computer. While most digital cameras offer you the option to shoot in b&w you have more control over your end results if you have the colour data to work with in your conversion on your computer.
Consider the subject
Some subjects lend themselves to colour but are not nearly so effective in b&w i.e a sunset. On the other hand, some subjects are ideally suited to b&w like faces and old buildings. Saying that landscapes can look amazing in b&w too.
Low ISO
Shoot with the lowest possible ISO possible. While this is something that most of us do in colour photography it is particularly important when it comes to b&w where 'noise' created by ISO can become even more obvious.
Low contrast
Many digital photographers prefer to shoot images for b&w in low contrast situations. So a dark or overcast day can be a great time to shoot outdoor b&w shots.
Consider composition
Look at shapes, tones and textures in your frame as points of interest as you don't have colour to draw the eye to the centre. Pay particularly attention to shadows and highlights which will become a feature of your shot.
