I shot and developed a roll of APX400 last night and hope somebody can advise me. I bought a load of APX400 on ebay (late stuff with green on box) then read how badly this film is rated on APUG and the other site??
Ilford advise 12mins at 20C and 10mins at 24C for Ilfotec dd-x. I gave it 10m 30secs at 20.7C which is a very little under but not much and I didn't want grain. What I got were rather thin negatives, that will need grade 4 to print and grain that wouldn't look bad on FP4 let alone HP5. Unless I have advice to the contrary I will expose the next roll at 320asa and give it a full 12 mins at 21C
Ilfotec looks as though it will control the grain issue with APX400 much discussed on threads but I dont think it could push this film even 1 stop.
I am not a lover of grain but would like to be able to push the film a bit and I don't think I am getting box speed with dd-x
