This object was in the staff room at work and I thought 'Ooh, a rainbow, that would be good to photograph for this week's theme'
Well it might look simple but it blooming well wasn't! This looks dull, flat and boring but you will notice IT IS WHITE. I took in excess of 100 shots, and this is number 2, so wasted nearly an hour on the others!! If I never photograph on white again I won't mind!!!
Black is easier. I am only guessing but do you have too much light. A faster speed or a larger f-stop. Also thinking painted wood without a finishing layer. Thus it is absorbing the light rather than reflecting it. But scientist I am not.
