I've recently shot a few rolls of Kodak GC. It is so cheap on B&H website that I ordered some rolls with my regular B&W film and paper. The results are mixed - I am very happy with some portraits and quite unhappy with some other shots (including portraits). I am shooting mostly outside but sometimes inside, without a flash. I'm going to try Ektar and Portra, but in the mean time I would appreciate if those of you who use them could give your opinions. Why do you like them? How are they different from one another? Thank you!
