Hi Rich. Yep, got them book marked and noted in my Dev cookbook folder. Why the variety of Devs? Experimentation or choosing to suit film/subject?
Do be sure to note the temp difference. Just happened to be warmer water some days so time adjusted accordingly to compensate. Otherwise often when the subject or scene is bright or contrasty I will over-expose 1/2 to a full stop and pull back development time 10-15%. I also primary scan my negs and find a slightly less developed (and less contrasty) neg scans better.
