Thanks for your advice, both of you.(posted 8302 days ago)I exposed the film at my normal EI of 12. My shutter speeds were either 4 or 8 seconds at f16 so I gave each shot a 4, 8 and 16 second exposure. One other one was at 16 seconds so I gave that 16, 32 and 60 seconds.
Normally I'd develop APX25 in Rodinal 1:100 for 7 minutes. I'm thinking now I may dilute the Rodinal at 1:200 with my normal amount of stock solution and give it 15 minutes or longer with reduced aggitation so the highlights aren't blown out.
