Hey dude - i've not even heard of this grey card, but thanks for the info - i'll keep my eye's out for one. I'm trying to get the cash to give my little fella a runout, and will wait and see how the lighting goes. I was hoping to get a dark, grainy, badly lit image but so you can still see stuff, and i've gotta wait and see what the original footage looks like, and then work from there. I'm sure a grey card is cheaper than a light meter tho!
cheers
