Small studio help please
Definitely make sure you've got very thick curtains/blinds for the windows. I know you're thinking about mixing ambient light from the windows with your strobes, but this sounds better in theory than it often works in practice. More likely with studio strobes, you'll be working at light levels where the window light will be negligable, and can be ignored as Sailor Blue suggests. HOWEVER, if you've got windows on three sides of the room, what you cannot ignore is the possibility of one of your strobes getting reflected in a window behind your model. This can happen even when theres a cloth backdrop between the model and the window -- the reflected light actually penetrates the backdrop cloth, even thick black felt.
