So I got a 120 roll of Agfapan apx 100 that expired in 07/2001. That I'm going to be developing in Sprint Standard film Developer. (shot @ ISO 100)

Since this is the first time I'm developing Expired B&W film. I'm wondering if there is a way to figure out the proper time or would the time listed at digital truth still be good (8.5 mins)?

For b&w thats 100 iso it will probably have little impact on the image quality. I wouldn't worry about it. If it was 30 yrs out of date or stored in the trunk of a car for 10 yrs that'd be another story.

hi

have you looked at the sprint systems website ?
they have 2 helpful charts ( one with films and development times ) and a 2nd one of variables ( expired film &c )

http://sprintsystems.com/time-charts/

agfa 100 is letter "N"
expired film suggests "+1" so you go to the time chart and jump from "N" to "O" for your development time


have fun !

( ps. there is an "expanded" development chart )

I forgot about their chart. that will help a lot of future rolls as I developed before I looked at the charts.

But from what came out it looks to of come out good. I'll post a few of the shots once it is done drying.

I would give it a stop more than box speed and dev for the std time:smile:
