Re: [APML] Undeveloped(?) spots on film?

[Jerry Lodriguss <jml@astropix.com>]

Hi Roland,

Sometimes dust or hairs will fall on the film during the actual exposure, 
and it can look like something in the emulsion, when actually it was from 
the speck masking the emulsion from the light from the sky.

Or, it could have been bad processing. Was the Provia 400F push processed?

Put up a small section at high res on the web so we can see it.
