Benzotriazole To The Rescue!

An excellent video for all those dipping into the use and rescue of old sheets for alt processes

Fantastic.
 
It was a good video Andy. I debated to get some of this stuff myself for some old films I have, but then decided against it, since I mainly scan all my films today. And that can be fixed in Photoshop.

...as indicated in the video.
 
Benzotriazole is also a sneaky tool to use when developing expired c41 film. really keeps the base fog down!

Well done as always, Andy.

I wonder how using Potassium Bromide as a fog restrainer would compare. I think Potassium Iodide can also be used but I'm not sure either have the same action as Benzotriazole.

You have to watch how much potassium iodide and Benzo you use since to much of a good thing can retard development to nothing. I found this out with some fogged paper I tried to save with Benzotriazole.

its remarkable how little of it is needed to make a huge difference as a restrainer. the small bottle ive got will last a lifetime.

Yes, and like I said, it's one of those chemicals we use where "more" is not always better. Still, it's a miracle drug when used wisely.

I would like to see the results of using TBZ for old printing paper.

I use the Moersch Restrainer, that is a mixture of Benzo and Sodium Bromide, for developing old Agfa Record Rapid FB from the 80th. Without the restrainer with a strong fog. With restrainer, it look like new with good whites. Luckily, I got 800 sheets of 9,5x12 inch for small money
Its also great for lith.
