Macbeth
Hello!
Can anyone tell me the development time for Chm400 at 200 ASA in ATM49 (undiluted, at 18°C or 16°C; 1-minute agitation)?
According to my calculations, the correct time at 18°C should be around 6 minutes and 14 seconds. Has anyone had different experiences?
I’d be grateful for any help!

Hello Shakespeare fan,
At 200 ASA, I develop the HP5+ in HRX. That works perfectly according to the instructions.
Otherwise, I develop the film in Rodinal; I’m not really keen on those grain-softening solutions like A49.
Best regards,
Franz
