I used a few rolls of film just to get started and just dropped them off at wal-mart having no pictures developed and everything put onto cd's. ALL of the pictures are blurry and a lot didn't even show up. Some even look like everything is moving in them when nothing is, and pretty much all look really grainy. I am new to photography and I have a Nikon N80 that I have been playing with since xmas. Anyone have any ideas why most my pictures turned out so bad??
