Re: [APML] Another Central Auriga

True.

The reason I don't think it's from humidity is that this fog is around every
edge in his shot.  Not just the marked edges....where it would be more apt
to be exposed to moisture in the air from being in storage/a new roll rolled
up...
If it is humidity why is it not across the whole frame?  The whole frame of
film is exposed to moisture in the air during the exposure.
Also, his film is not hypered so it can't be moisture related as far as that
goes.
