Age fog

[robotgoldfish]

I was watching some b+w reversal videos and started to wonder if reversal bleach before developer will remove the fog from long outdated film?

Unfortunately I used up the last of my really old stuff and cant test this myself. So if anyone has tried this or is willing to try this let me know how it goes.

I suspect that the bleach would remove the latent image along with the fog. That's just a wild-a** guess though.

Reversal bleach removes silver metal, and won't do anything if used before development, when only silver halides are present.

Some of us have "Age Fog" and it has nothing to do with our photography. ;-)

I've never done it, but you might use some benzo to eat through your fog, unless you use the fog to your advantage when you expose and make your prints ( which I do all the time ) ....

...pop some benzo's to eat through my age fog? Or...I can use age fog to my advantage? - how does that work

Oh...now I see...and yes I do agree because I have some ancient (1988 expiry) 11x14 Tri-X - which has over the years experienced multiple moves in storage conditions including some very hot attics...which I'm now pressing back into service with a bottle of (get this!), circa. 1978 (!) HC-110 (gifted to me by a generous forum member) black as tar....and it works! (and yes...still some nice fog - of which I can certainly take advantage!)

(...and John, there is a bit of irony in your recent PM suggesting I try a little caffenol to cut through my age fog!)

(...and John, I have to laugh at the irony of a PM you'd recently sent regarding the use of caffenol to cut through age fog!)

That’s cause caffenol use makes a nice sheen of fog on its own sometimes you don’t realize your film was foggy lol .. cuts the fog like it’s the hair of the dog .. or a punchin the nose and you forgot you stubbed your toe.. I’d have suggested RG use caffenol and d72/ansco130. But I figured he wasn’t a true believer.. and might think I was messing with him ( as people tend to think if I suggest coffee strong print developer).

The original thought was to remove the metallic silver that "printed out " due to conditions. But that would include the latent image.
But you could probably clean off the fog before exposer. Not worth the effort unless the film is irreplaceable.

I also have Brain Fog

so what?

we all gotta go

I don't drive for the safety of others

I have a private driver on call

I stay home

Last walkabout was to get a 6th shot

My recent experience with very old film turned out quite well. I found that there was about a three-stop loss in speed in Tri-X that is 50 years old. That was with normal development. It made for long exposures when printing, not a big issue. Your results will be different- how could they not be? But might provide a starting point.
