Anti-halation layer blues...

[Steve Mack]

I am curious about how to remove or lessen the anti-halation layer in my 35mm film. It's Tri-X. I'm using HC-110 at 6 minutes, with agitation for 15 seconds every minute. What am I doing wrong? I'm processing the film in a Patterson tank, BTW.

Thanks for all who reply.

With best regards,

Stephen

A pre-soak will keep your developer from turning blue, but the dye is not harmful for the developer. However, from your description, you are doing nothing wrong. Can you describe what sort of problem you may be having?

This particular strip has a pronounced blue cast to it, which remains even after fixing and washing. It makes the images look slightly under-exposed. I've had films with a slight blue cast in them immediately after I remove them from the reel, but it was always gone in the morning after the strip had dried.

Regards,

At least part of it may be due to a dyed base material.

How old is your fix? There's a similar thread on the pink cast of TMAX and it seems to conclude that it's from inadequate clearing in the fixer.

Just my 2¢

Refix with fresh rapid fix, rinse a couple of minutes, then into HCA - hypo clearing agent - for a couple of minutes, then wash fully. The blue dye should be gone after that.

Enough of this already. Kodak's TMax films exhibit a distinct magenta color cast if fixation and/or washing is insufficient. If you've done the fix and wash correctly, there is no color cast. Tri-X is a different animal, and what applies to TMax films does not apply equally to Tri-X. No matter what you do, Tri-X will have a very slight color cast. That's just the way it is.
