I have been shooting this for inside sports this winter. I found that I needed to extend Ilfords recomendation by 1.5 min to get the results I want(@3200 DDX 1-4). I am however still experimenting, and that is the key.(posted 8513 days ago)The strange thing about shooting this film is that, many times posted pictures get burned for having to much grain, but the same pics shot the same way with say HP5+400 and a flash get burned for looking "artificial".
Be ready for the grain critisism, but if you like it, and the recipients of you efforts like it, don't worry!
I have some basketball shots on my site http://www.bwphoto.itgo.com under the local sports section, football was shot outside with 3200(games started late afternoon and went under lights by the end), I had a very slow tele at the time and that was the option I chose to get the action, the first set of basketball shots are 3200 exsisting light, the second set (as noted) are same gym with HP5+ and Flash. When shooting inside, I use a sigma EX HSM 70-200 2.8, or a Canon 135 2.8, allowing me to open up and shoot faster.
IMHO 3200 has a place in your bag, it, like everything else, takes some trial and error, to get it right, I'm still working to refine my processing, and don't plan to give up...!
Good Luck!
