It was Delta 3200 that really started me on this track of experimentation. Delta 3200 is a gorgeous film that I am really beginning to love. I know many photographers prefer the traditional grain over t-grains, but there is something about a fine, t-grain at a high iso that just sings. The unfortunate part of Delta 3200 is the price. At $9.29 per 35mm roll on BH, it's not a film most would be able to queue up often. This makes it hard for photographers like me that do not get much time in bright light. I googled some sample shots of HP5+ being pushed to see what the possibilities might be for getting close to 3200. I knew I was in for some intense contrast, but with HP5+ going for $5.19 a roll, it was definitely worth a try. This is especially so, since I find Delta 3200 is merely "ok" in my personal preference at box speed. It truly shows its beauty at 1000-1250 EI developed normally.
So I did my first attempt at pushing HP5+ to 3200, and I have to say that I am much more pleased with the results than I thought I would be. It is very contrasty, but I do like some extra contrast at times. I think this method will really help in low-light pinches where I still want to utilize film over digital. I have to be pretty close on my metering. It is really easy to block up your blacks at a three stops push. I think this is the limit for my personal tastes in 35mm format. I am really tempted to push a roll of it in 120 to 6400. Check out some examples of this experiment below. These were all developed in DD-X 1+4 for 14.5 minutes at 75 degrees.
