Interesting that this thread surfaced when it did. I did some photography in an amphitheater where my son's school play was. It was a great performance, and I wanted to give something to his school, so I dragged a medium format camera with a 300mm lens and a 2x tele-extender with me.
I shot from about 150 feet away and got some interesting shots. I used Delta 3200, exposed it at 3200 and developed according to the 6400 recommended time by Ilford in their DD-X chemistry. The negs turned out super, so the recommendation of developing for longer than Ilford recommends I think is definitely a good one (for my purposes anyway).
Not to say that Ilford is wrong, but I have a feeling most folks use D3200 in poor lighting, which means indoors a lot of times, and if I remember correctly the film speed slows down some in artificial lighting compared to daylight. If that's the case, it all makes sense.
I love the look of the film / developer combination and will continue to use it for low light. When I get something printed I'll post back here with examples.
