Hi. So, the volunteer tutor coordinator at the after-school program I work at asked me yesterday to take some pictures to use in recruiting presentations. Fine. BUT then after I've already agreed, he tells me that he wants me to take them on his "old Nikon film camera." From the way he described it, I'm pretty sure it is an SLR, but I'm a bit nervous about using a camera I've never had any experience with before. (The reason he wanted to use his camera is b/c the price of slide film is less than the cost of converting digital to slides. Understandable.) Anyway, so here's my questions: 1. Are there any major differences between shooting with digital and film SLRs that I should know about that? I've never used any kind of film SLR. 2. What are the most major differences between an "older-style Nikon" and my beloved Rebel XT? Thanks bunches for your help!
