When I get some of my slides back from the lab, they have black "splotches" all over them, it can be cleaned in ps, but they also scan really badly, alot of noise and way too contrasty, they seem overexposed on the whites, but underexposed in the shadows. I nearly always use Sensia 100, and some films turn out just great without a spot on them, no problem scanning, but about 25% of my films are bad like this. Some slides even have long scratches across them. Is this due to bad processing or bad film??
Anyone experienced the same??
