I've been frustrated with my fix time over the last six months.
I use to use your basic Kodak fix with hardener for paper for years and hovered around 30 seconds.
Then something changed
Now I'm using a (suggestion from Dave) dilute fixer by a third or more but it still seems to clear very fast and shift blue. I'm like in the 10-15 second range now.
I tried light fixing too which works somewhat but hard to stay consistant.
Sunday morning I shot and got OK looking yellow/green holograms that I used to make a master. The next day, using the same fixer the were beyond blue. Temp was a bit warmer everything else the same (same energy object and baths)
Now for the disclosures. I keep my film in a cooler with some dissicant inside to keep them dry. Could that make them too hard?
Also, I've asked this before but how long does a dryed out plate sitting in a humid room take to swell? Meaning is it seconds, minutes hours or days?
I hope DCG has not gone the way of the Russian forum

old film will be clear (hard) ther is a process to use for hard films I will have to look it up.. but that process uses a acid to soften films... it works realy well from green holosTony wrote:Many thanks guys
Yes Dave same laser
I will give it a try
Any speculation on what could be happening? Film aging? Old film need less fixing right?
