I'm used to most things in photography having some workable algorythm for success. There are processes and calculations to get a proper exposure or depth of field etc.
But gels seem to be trial and error.
I was shooting a basketball game. Before the game was parent recognition night. I would have liked to shoot the parents and kids at center court with a little fill flash but I didn't know off hand how to gel my flash.
I know this court is ~4000k and +25 on the tint slider for correct WB. Is there any way to convert such settings into a gel selection?
