I would be grateful for any insights regarding using a flash indoors to expose 5 rows of people evenly. I recently shot a friends family on a set of stairs, I set the flash to bounce up and slightly forward of the ceiling. I was perhaps a meter and a half from the first row. The first row was way over exposed and working its way back, the last row was nicely exposed.
Am I to presume the only way to get a decent scope of flash exposure is to place the flash off camera and bounce it directly above the group?
I could come up with all kinds of ways of trying to deal with this but this is the easiest way (in my opinion) that will probably work. Instead of bouncing the light directly over your subjects, try turning the bounce head to fire up into the corner of a room behind you, so that the walls and ceiling act like a giant brolly. This will help spread out and diffuse the lighting. It will look a bit flat and not very exciting but it may sort out your immediate problem. Then read up on the inverse square law.
