This summer I intend shooting some slides wile on vacation, that I am planing to develop myself (manually, not using a rotary processor). Obviously, I want to avoid ruining my holiday pictures, but Velvia colors are too amazing not to give slides a try. I'm scared though by the narrow temperature tolerance limits.
Now, is E-6 development that tricky? Did you get it right from the first try? Is manual development good enough for quality results?
