I have seen this (I think) A couple of days ago I went to check the times for developing Kentmere 100 at half the stated ISO setting and was surprised to note that since my last visit a lot of information about Kentmere films has dissapeared. There is now only one guide for 100 ISO film and that is at 50 ISO at 1-50 dilution as I wanted and none for the standard 100 ISO. There were two however using the 400ISO version.
