Trying out stand development for the first time,I exposed 9 frames of Fuji Neopan 1600 - 3 frames at 400 iso,3 frames at 800 iso,and 3 frames at 1600 iso. I then developed using Rodinal diluted 100:1 for 1 hour using the stand method - 30secs initial agitation,then leave alone for 1 hour. To MY surprise,all frames were very similar(standard test subjects),as if I had exposed them all at the same iso. Is this to be expected - use any iso you like with stand development ? Apologies if this has already been answered,but I couldn't find anything through my searches.
