Thilo, TXP actually pushes quite well. In this instance, I was presented with a fleeting opportunity in low light, and pushing was the only way to get the shot. Which was fine by me, because I wanted quite a lot of grain to suit the mood of the image.
I ended up usng ID-11 and it worked out OK. I duel selenium / sepia toned it. Will be printing more of them today and may throw a few into the gallery.
