I need some input on how to go about this. I normally shoot manual flash. I am not usually in a situation where I am moving around and the flash-to-subject-distance is changing but I do want to explore that avenue now. I'm going to be using a Nikon FE2. When I've shot digital, as I said, I use manual flash because I have an external meter and usually take the time to set things up but I have used TTL also. (for bounce flash where the subject-distance is changing constantly) I'd like to use TTL on my FE2 now also. Is it as simple as setting the flash on TTL and forgetting it? Will the FE2 know what to do? I guess I've never really thought about how or why TTL works, I just used it when I needed it. Can someone fill in the blanks on how this is done?
