Quote - I did a little test file up in Photoshop, using the basic three circles of primary colour and desaturating the thing afterwards, to find out the relative luminosities of different coloured light. Would this b of help to anyone who wants to give their images the look that they've been coloured, without actually using colour in the lights (if that makes sense?)

Yes, I would be interested :) To me light is the most important element in a scene and it can make or break your image. Anything that can help make good lighting, is of extreme value :) I'd love to see what you came up with and how you did it etc.

able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
