    The Massive Developer Chart (http://www.digitaltruth.com/devchart.html) has suggested times for Efke films in Calbe developers. Those times should, of course, be considered as starting points for your own testing.

    It was my experience with Efke 50 and 25 (in 4x5 and 8x10) that you needed to double the recommended development time in order to get an acceptable neg.
