  1. I have recently noticed a large number of dust-like clear spots on my black & white negatives, but they are only visible with the negative held at an angle to a light source. The spots are not visible when light shines directly through the negatives, and they usually do not print. (I say "usually" because I have noticed on rare occasions black spots on prints that I cannot explain.) I looked at some older negatives (different film type and different developer, but all Ilford) and saw the same thing. I only now have accidently discovered this while viewing a negative with a loop. Could this be caused during manufacturing? Any ideas?
  2. Concerning the parts here about fixation and one bath vs. two baths: It all depends... I think one bath can work just as well for archival purposes under certain conditions. Two bath works economically only if you reach capacity in the first bath well before the tray life expires. I did some math to prove this point. If anyone is interested we can go over the math together to see if it makes sense.
