I just purchased an SB-25 flash for my Nikon FE film camera. I have shot film for a while with available light but I don't have any experience with a flash. I've read many forums and blogs about using a flash but they all are assuming you are using a digital camera. With film, you don't have the capability of taking a shot and checking histogram and whatever else and adjusting from there. What is the best strategy for getting your first shot close in exposure so that bracketing will get something good? Is it appropriate to set up for the ambient light and then open the aperture a couple stops?
