Tri-X + Rodinal: 200, 400, 800 dev times?

[sockeyed]

A while back, some brilliant person on this forum posted the development times for Tri-X in Rodinal 1:50 @ 1600, 3200, 6400 and 12800 using very limited agitation (once every 5 minutes). I've used this technique with great success, getting nicer grain at 1600 and 3200 than I do at 400 using traditional developing.

Does anyone have the development times for Tri-X in Rodinal 1:50 @ 200 or 250, 400 and 800, using this same limited agitation technique? I'd love to try it out.

Thanks!
Ben

I know this is a very old thread... and I do mean very old... but it is a good thread that I think deserves attention.

This is done using a slow agitation technique - one very slow rotation (takes ~8 secs) every min, with same slow rotation for first 30 secs. The grain is manageable enough to get decent 8x10 enlargements in the darkroom.

Here is a TMax 3200 (shot at EI 800) developed in Rodinal 1+50 for 14 mins 30secs @ 20degC. The grain is huge when you see it in the darkroom.
