I've been using Acros a lot lately. Depending on the developer you choose, it can produce great tonality with grain as fine as anything on the market. I'm not sure Acros' grain is any finer than TMX, but then I always thought TMX had finer grain than Agfa 25. I think it depends a lot on the developer you choose.(posted 8216 days ago)I've been experimenting with FG-7 and adding sodium ascorbate. From my preliminary tests, it looks like a great combination. Exceedingly sharp and fine grained.
I use 1/2 oz. of FG-7 to 14 oz. H20 and I add 1/4 tsp. of sodium ascorbate (not l-ascorbic acid!). Develop FP4+ for 7 min @ 70 degrees in a rotary (constant agitation) processor. If you use tanks and intermittet agitation, try increasing the development time by 20- 25%. Acros and TMX should need about the same development time.
