I have been asked to take some black & white portrait photos for a new theater company for them to use on their website. I usually take photos in color and then turn them to black & white in photoshop if I want to (I like that flexibility). My problem is that the theater company wants to edit the photos because the subjects will have a blue screen behind them. I don't know whether to shoot them in black & white to start with so I can see what they look like. Also, with the stage lighting and the blue screen, I am not sure if the lighting will be right. They know I am not a professional and understand that the photos won't look like they were taken in a studio, but I don't even have a separate flash gun, only the built-in flash. I still feel obliged to do my best for them, so any tips would be much appreciated.
