196? verichrome 120...how rate and process?

[jtk]

Forgetting snip test, how would you rate/expose ancient Verichrome? I gave it to somebody with a toy camera, he may figure out how to shoot for different wild approximations of exposure ( click, advance, click click, advance, click click click advance etc) but he will undoubtedly give it to a lab to process.

If I was going to process it I'd probably rock it back/forth in a tray while viewing occasionally with a green safe light (if I had a green safelight, or even a darkroom). But I don't think a lab will want to go to the effort.

Any ideas?

Verichrome will be older than the 1960s -- it was discontinued in 1956 or so. Do you mean Verichrome Pan?

I recently processed some Verichrome (ortho), and got pretty good results with 5 of 8 frames having readable images and the rest unexposed. I used a custom mixed developer and developed by inspection, however, and didn't attempt to expose the rest of the roll (it had been wound through before I got it). Bracketing is probably the way to go, and development (equivalent of 17 minutes in D-76 stock solution) with a strongly anti-fog developer...

I'm moving this to the Black and White Film and Developing sub-forum.
Is the film Verichrome, or Verichrome Pan?
If Verichrome, my adventures, as recounted in this thread, may give you some useful information.

There is no "Black and White Film..." sub-forum. Just fyi.

True - it the B&W: Film, Paper and Chemistry sub-forum.
For some reason the thread move didn't happen before.
It has now.

I gave it to somebody with a toy camera

If the camera is used outside on a sunny day, it may get some images. Normally, toy cameras have small apertures (f11). The film is probably somewhere around iso12. If lab developed, it will look like a strip of grey plastic when he gets it back.
