Re: [APML] Black Negs a new developement

Hi Again Brian,

Did not realize you were working with 120 TP.  I would check your changing
bag and developing tank top too.  The unrolling of the film before
processing and all of the steps including loading it in the tank up until it
is fixed are also suspect.  If the entire roll is black it was hit by some
serious light.  What was different about the processing of the daylight
shots?  It might be worth wasting an unexposed roll to see if it is the
developing process that is causing this.

Keep at it, 120 TP is worth the hassle......

Jim
