In Paint Shop Pro v. 7.02, I then stonked brightness to 90, contrast to 80, and saved the image again.
My scanner glass is a lot cleaner than Hoagland's (we haven't had any office parties lately,) but the effect is nevertheless clear. Smears and sparkles are picked up wherever the image is black. The resemblance to this, which Hoagland & Bara swear shows Al Bean under a glass dome, is fairly striking.
Again, scanner sparkle in the blacks, including Al Bean's shadow. This is another of Hoagland's scans from the Ken Johnston collection, and he's never explained why there's "glass dome" material down there on the surface.
RetouchingHere's what I think accounts for the accusations we hear about NASA "airbrushing" Hasselblad frames for release. I think it's well-nigh impossible to eliminate the sparkle altogether, on something as absolute black as the lunar sky. So I think some sparkle quite likely was removed. If working on a print, the tool was more probably a black felt pen rather than an airbrush, but the purpose was the same—to give a truer rendering than the printing process provided. And, once again, this could not have been done on a negative, as Mike Bara has alleged. That would mean eliminating black spots instead of white ones, and turning them transparent. Impossible, basically.
