Currently I have been shooting alot of sporting events ( i.e. hockey games) for my husbands' hockey team... I am having a problem with graininess with some of my pics. I am shooting with a Nikon N80 most of the time and using a tamron 70-300mm. I contacted the photographer for the Star Tribune and he suggested using faster speed film, so I bumped up to 1600 and that helped a bit, considering the lighting in these arenas is kind of crappy. Any suggestions would be greatly appreciated. I have gotten some great shots but it is really depressing when the pic doesn't turn out as well as it should.
