Hi, I've just shot a couple of rolls of Delta 3200 and am about to develop them. I've read that high-speed films can't be developed properly with the same developer you'd use for slower films, is this true? I'm planning to use what appears to be generic developer. I'd run out of D76 so I bought some Fotospeed FD10, which was cheap but was the only developer the shop sold, and claims to be a "fine grain one shot film developer". Anyway the developer lists suggested dilution ratios and development times for various films, one of which is Delta 3200. The problem is I've been informed that high-speed films are not actually high-speed films and have to be pushed to the speeds they claim to be (this is new to me). Now maybe I'm getting needlessly confused, but does that mean the time given for developing Delta 3200 is for when the film is rated at 3200, or for a lower speed? I metered for using 3200 iso film, so obviously would like to develop the film accordingly. Thanks in advance.
