[Digital BW] Re: PMK Pyro - Also check Pyrocat-HD Formula

2005-12-15 by Christopher Lovi

In response to your streaking issue.  Presoak your film with 
distilled water for 30 seconds or so.  It will soften the emulsion 
enough so when developeer rushes thru the sprocket holes development 
is more even.

Hope this helps
