Thanks for all the info guys. I think though, DarK_Jedi was after more of a step by step guide or something similar as a way of getting started into this sort of thing. I know I'd find something like that very useful as well. There are little bits and pieces of info on colour correction etc scattered around the net, but nothing comprehensive or complete (and free) that I can find unfortunately.

I found this here on the Doom9 site which goes into some basic correction near the bottom of the page and a bit more here.

Theres also some good info on Zions X0project site here on setting black and white points and other info which will be very useful. I know black and white points are not 'colour', but this is a hugely important part of the whole process and will affect how the colours look in the finished video. Defintely well worth a read.

Hope this helps.
