I want to become proficient with my 35mm minolta X-700 to learn the intracacies of photography. Ive taken alot of pictures with my old X-350 and they all turned out great. Im not sure if it is my 800 speed film, or the lens, my selection of fstop (I usually go as low as possible when the light is bad, but as my lens is a 19mm to 28mm that shouldnt be a big deal, everything is pretty much in focus), or the ambient light, but all my pictures turn out very grainy, much more that 800 speed film should be. I would like to know what causes this grainyness and what I can do to prevent it. If I let the camera just do what it wanted, would it turn out the same way?
