it looks like a problem that happens on some high resolution scanners. if it 
is this problem, it's caused by slight bubbles in the emulsion during 
manufacturing of the film. the only way to be sure is to look at that 
portion of the film under a microscope. a 20X loupe isn't powerful enough. 
you need at least 40X and preferably 80X or so.

  What more, I got these weird black speckles in the luminance
  channel, leaving me dumbfounded. Please see
  http://3web.dkm.cz/members/fotof/temp/lumaspeckles.tif for 100%
  4000dpi sample (L channel only). USM does accentuate them a lot.
  Anybody knows what it might be? I always scan with any sharpening
  turned off. ICE on, and both GEM and ROC disabled (I found the GEM
  feature to hoover extremely).
