I rate Porta VC and Fuji Astia at 100. I would like to rate a B&W film at 100 also. But, I have not found an emulsion that rates at 100. I shoot TMX at 50. Has anyone done test with film and developer combinations that rates an emulsion at 100?

I get fine results rating Agfa APX-100 at ISO 100. I develop in Wd2d Pyro for 12 minutes. Of course this film is now getting hard to find, since manufacture has ceased.

Do you use trays, tubes or tanks?
I get an EI of 125 for FP4 in XTOL 1:3.
Same as Ron Marshall but I meter at 100.
I shoot FP-4 and Plus-X at 100. PMK Pyro for the FP-4 and D-76 1:1 for the Plus-X. APX 100 at 100 in R-76 1:1. Verichrome Pan at 100 in D-76 1:1. You can pretty much rate B&W film however you want. You just have to adjust your metering and development times to make it work for you. That takes testing. Nobody's opinion will take it's place, I'm afraid.
Sorry, I meant to say APX-125 rated at 100. I use stainless steel tanks, with inversion agitation by hand. Agitation is for 15 secounds out of every 30 seconds., so 15 agitate, 15 rest, repeat.Quote:
