Jim: do you mean to say you brush every area in every picture to match WB? That must take a lot of time! I tried brushing in to fix the ones my flash screwed up but found it both very hard and very time consuming so think I will leave them and write it up as a learning experience.
Oh no, I'll do that if the photo is worth it but what I mean is that if I don't mind if the camera doesn't get data on the gel. The WB is either going to be acceptable as-is or easily adjusted in post in LR anyway.
Ah, I see , yeah that I can agree with, only the custom WB is tricky for me being colorblind and using the small screen. And I don't know the color temp of the gel so I have to guess what to set it to in camera. And when I tried auto function with flash on camera it just worked, I really liked that.
How do people usually choose the right gel for a given light, and not just ballpark it?
