Re: Dust on Digital Sensors

[Jan Faul <jan@xxxxxxxxxxx>]

I came to my darkroom one afternoon in the 70’s and found that my assistant and her boyfriend were waiting for some film to percolate in photo-flo and distilled water while they sat on the sofa and drank very dry Martini’s (gin and a distilled water ice cube with a couple of drops or Vermouth).

That's my experience as well, little of the stuff I spot could have been blown off.  (I do blow off what I can, though not with as sophisticated equipment.)

Much of what I'm spotting off is *my own* poor lab technique when I get into the late 60 and the 1970s.  None of the darkrooms I used in highschool or college had water filters, and it took me several years to discover that a final rinse in distilled water (and diluting the Photo-Flo with distilled water) helped a lot.
