I have a problem with some of my shots, the people in it are correctly focused, but the background is totally dark. The back of the room is approximately 10-12m away. This is my camera setting:
Manual mode, F4 (biggest aperture liao), 1/125, focal length 100mm, Flash (Metz 32Mz2) in TTL mode, Fuji Xtra 800 (rated at 640, but this doesn't matter right?)
Also another problem, the DOF is very narrow. I spot focused on the bride's eyes, but the groom is not in focus due to the narrow DOF. On the photoalbum it's ok when viewed from far, obvious when near... if I were to stop down the problem will be worse right?
This problem only occured at this particular focal length in the particular set of pictures. At 200mm, 50 and 28, the background is ok, but some had lack of DOF.... though for the 200mm, the picstures taken were not so "close up".
PS: Not wedding photog. Just firing from my seat.
