Tri-x Reversal Turned out Sepia. How to avoid?

[HumbleP]

Hi,

I recently processed some 8mm B&W Tri-X in chemicals mixed from scratch. The resulting image has a sepia tinge which I don't want.
Just wondering how how I can alter my brew to avoid this?

Thanks
Peter

What developer did you use ? Did you use a clearing bath after bleach ?

I mixed my own D19 + Sodium Thiocyanate in the first developer.
I did use a clearing bath.

In my D19 I used Potassium Carbonate instead of Sodium Carbonate

What did you use as a second developer?

Yes it is the second developer that would determine the color of the images. The negative image created by the first developer is completely destroyed in the reversal process.

The 2nd developer was the D19 (home brewed!) sans the sodium Thiocyanate

Is it anything to do with insufficient clearing after the bleach bath?

wow--many things can do that...insufficient clearing can do that--the dichromate will leave a cast to the film that will not go away--if you are using dichromate bleach, then that is first culprit--try more rinse/clearing before reexposure

also perhaps not entirely getting rid of the antihalation in the first developer before bleaching---that stuff reacts with bleach and leaves a cast to the back of the film.

yhe sepia may also be due to fog..it's the color of the very thin layer of silver that didn't get developed in the first developer-but DID get developed in the second developer. Or the developer left a cast to the film (or both)...

try a different second developer and see what the results are is best suggestion...
