Agfa APX 25 Reciprocity Failure for Long Exposures


New Member
Good day,

Does anybody have information on reciprocity failure when using Agfa APX 25 film for long exposures? I have recently acquired some and wanted to try long exposures with a 10 stop ND filter. Specifically, I am interested in exposing for times up to 2 minutes.

Thank you for your responses,
