> normal for Delta films?(posted 8637 days ago)Yep it's normal....you need to do the _rest of the process_.
After the fix, treat the film for about two minutes with continuous agitation in a hypo-clearing agent, then wash for about 15-20 minutes in an efficient washer that has a good flow. This will clear the leftover sensitizing dyes.
You can use Ilford's HCA, Kodak, Orbit Bath, Perma-Wash etc or make your own. Manufacturers claims for HCA appear to be rather optimistic, but otoh film washes easily so it really doesn't matter how long it takes as long as you get sufficient changes of water.
To make your own HCA, just dissolve a level tablespoon of sodium sulfite in a quart of water and use it as you would any other HCA.
