Welcome. Try this link...some good information. Also, I'd consider picking up a copy of Photography (7th Edition) by Barbara London and John Upton. Great book (it's used by a lot of photo classes). If you're just going to experiment with different films, keep one thing in mind. Just because films have the same speed, don't think they are all the same. They each have their own characteristics. So, don't think because Kodak T-Max 100, Macophot PO100, Ilford Delta 100 and Fuji Neopan ACROS 100 are all b&w ISO 100 films that they are the same. They each have their own amount and grain sizes, exposure latitudes (you'll understand this after reading abit on exposure and film), contrast, etc. That said, trying the different films out yourself is the best way to see how they behave. Good luck. -=>Donald -=>Donald
