This may be a rare case where somebody is brand new to any SLR camera, film or otherwise..... and totally clueless, not even knowing where to start. Nothing wrong with that. Everyone was there at one time.
If this is the case, it may be the best to find someone, an old timer maybe, to show him how to use it. It can be daunting to read about aperture, shutter speed, etc, etc, etc and try to apply it to the camera in hand. It's SO easy if someone can show him in person.
I have no idea where in the world he lives but if he is in Central Florida, I'd be glad to do the "old timer" thing for him. I'm sure there are plenty of APUGers that can do the same.
