I have been meticulously careful cleaning my holders before loading. I wear
only vinyl gloves while handling this film. I load the film with great care
and very slowly.

I tray develop the film 2 to 3 sheets at a time in a 5x7 tray emulsion up.
My next step is to process sheets individually ( what a pain ). I have
noticed "scratch" marks that seem to be present on most if not all of the
sheets that appear to be identical and in the same place that have been keep
in separate holders.

The odd thing is that upon close examination of the "scratches" there
doesn't appear to be physical damage in the emulsion or base side of the
film.

I have suspected that this damage may have came from the factory.

I would be happy to snail mail a negative to someone experienced with this
film to get their opinion.

Don
