The Ilford sheet states the development time of FP4+ 35mm film with ID-11 (1+3) as 18min. However, the Mega development chart in the net says 14-15 min with the same developer. Does anybody know what the (more) correct time is? At the moment I rate this film at EI 100 and develop for 17 min in ID-11 (1+3).(posted 9210 days ago)
