help with crescent moon crimping
I am looking for help/suggestions to remove the crescent moon crimping marks
on a roll of 120 negatives where I had trouble loading the film to reel. I unfortunately didn't process the film soon enough after exposing (months) and subsequently the film became difficult to load, especially at the end of the role (beginning of the exposures). The film developed well enough except for the crimping. Fortunately, the negative has a totally black background (clear on the negative) and the crimping is within this cleared area and does not interfere with the subject. I can maneuver the print during the printing process to eliminate the crimping in the final print but I would like to know if it is possible to completely remove the crimping mark on the negative permanently without damaging the negative. Any suggestions would be greatly appreciated. Thanks. |

I doubt you'll be able to fix it for optical printing, you may be able to spot out the area(s) affected....the best fix may be possible by (gasp) using a film scanner and outputting the "fixed" image file. Seems like a good reason to justify digital work But you never know, maybe rewashing the negatives and heat drying them in a drying cabinet may work. -- George W.

You can bleach the emulsion clear with Farmer's Reducer, applying to the crimp mark with a q-tip. If the celluloid has a crimp mark in it I don't think you will be able to get it out. -- Nicholas O.

Won't that leave a big black spot on his prints shaped like the moon shape ? If the celluloid has a crimp mark in it I don't think you will be able to get it out. -- George W.

Its much easier to fill white or light areas than bleach out dark ones. Local relative humidity seems to have a effect on how limp the film is when you load it. I've found that with the stainless steel Nikor type reels I use that cutting the corners of the film will help getting it started in the reel. I am not quite sure why, perhaps because the edges don't get it cocked in the reel. I've been using SS tanks for 50 years now but still occasionally have trouble with them. -- --- Richard Knoppow Los Angeles, CA, USA -- Posted via a free Usenet account from http://www.teranews.com |
