Advice On Uneven Development On Film Edges

[Steve Sherman]

For what I call standard development with Pyro 1+1+100 I agitate for the first 30 seconds and then 5 inversion every minute.
Steve, are you suggesting that this first 30 seconds is crucial and it this period that should be quite vigorous.

A longer initial agitation for sure, the added density that results can easily be compensated for later in dev. stage after uniformity has been established. Also, with the EMA process, I have found the inversion method to yield more edge unevenness than a simple rolling agitation with change of direction every 20-30 seconds. Good luck

Update:
I changed the way I agitate in the SP-445, took the advice of Steve Sherman and others and I am pleased to say that the last 4 sheets developed in Pyrocat HD are 100% better.
I haven't tried the 510 Pyro yet but mainly because I am not all that struck on that developer.

Thanks for all advice.
