Hello i was wondering, if you shoot IR, you have to make a custom whitebalance. You take a pic a green grass (with only the grass in the frame) and set that as a custom white balance. Right? Well, cant you just have a piece of green paper or something like that and and take a pic of that? so you can use that as a white balance? Cause there isnt always a patch if green grass nearby, you know Thanks for any input. Greetz Daan.
