Andy,

Interesting stuff, so I will keep an eye for how you get on with it.
I have memories of viewing gallery images taken on pushed Tri X and being really struck by them. Then I also liked Ansells prints with not a hint of grain, well they were near enough contact from 10 x 8 negatives. It was his work that sent me into Tech Pan territory. After using that FP4 developed in microphen looked grainy
.
Duncan has a good example of use of grain in his gallery - link
