Although I am a true amateur, I have been solicited to make photos at the wedding of a cousin's granddaughter. I have an SLR with a bounce flash. I was going merely to use Fuji ASA 100, but I have discovered that apparently there is film especially designed for such occasions, designated ASA 160. I find that there are competing brands and subdesignations within this catagory. Does anyone have advice on this matter, while bearing in mind that I am no more than a casual photographer? Thanks in advance for your tips.
