I got my first slides back, from my trip to NYC... some provia and some sensia, all 100. Wondering if I could get some insight as to why my photos are SO grainy and the colors not nearly as good as they should be. My exposures are correct, though... I kept them in the fridge when I wasn't out. However, all of my rolls went through the airport carry-on luggage scanner once. I read that this would be no problem. I also walked around for several hours a day with a few rolls in my backpack, in the heat. Could these factors have affected the outcome? My BW and negatives all turned out. Maybe it's my lab that sucks? Will post photos once I upload them.
