I know this should be a simple concept, but I am lost with how to properly shoot a grey card.
It has to be in flat white light (unless you want to color correct out color, like the green from flour.) But does it have to match the same exposure of the scene your shooting? Kodak and wut I've read says it does, but my confusion stems from if you have two key lights and you need to set the card up in the alternate posistion, (if your going for special exposure or lighting i.e backlight) they reccomend putting the card on an easel and lighting it with one light, how can you get the same exposure with one light if your using multiple to light a scene? I know you could raise the intensity of the light by moving it closer but to avoid glare i read its better to leave it far away.
If your scene is a 5.6 and your one light gives you a reading of a 2.8 on the grey card, and you expose properly for both will they both come out as average or will a timer leave the 5.6 as an overexposed image?
I know this is more of a film question rather than DV, but I'd appreciate some clarification.
THANKS
