I was sort of under the impression that longer developer times resulted in a general increase in the size of film grain. Generally I'm looking to push grain size down as much as possible. I tend to be using Delta 100 and Delta 400 (shot at 200) and Delta 3200 (shot at 1600) and processing in XTOL. Over the weekend I shot TMAX for the first time and I'll be interested to see what happens with it. I figure using its own developer is the best trick for it, right? I know these are probably pretty basic and old questions but I'm trying to grapple with the science that's involved here. Best regards, Adam Bridge PS: This is probably my own cheapness at work but it bugs me to have to do tests on 24 exposure rolls. I know that I should be processing test shots in the same way that I'll be doing my real rolls - but everything screams: wasting money wasting money at me. Sigh. I assume to do my own tests I should buy a brick of film (which I assume will all be from the same production run - is this assumption correct?) and then create a standard test scene that has a generous dynamic range to it, shoot it the same way every time, and then process the film in a variety of different ways (making careful notes along the way.) What I'm not sure about is how to then evaluate what I'm seeing in the negatives. Okay - now I've revealed my true inexperience at this - but hey - how else do I learn? <grin> Thanks for your answers.
