Thanks, David. Will definitely be giving this one a read. An early photography
mentor of mine had a radioactive lens - one of the APO-Lanthar 4x5 lenses from
before I was born. OMG what gorgeous colors it gave. He loaned it to me for
some of my Large Format coursework back in College. After I'd used it he sold
it and bought a nice used car with the proceeds!
Sadly and much to my regret every single image I shot with it I *ruined* mostly
in trying to process the film. Be it Scratches, dings, ripples, creases, stuck
together, or exposure setting errors, or even all of the above. Stack of
useless plastic sheets in the end.
A problem I only could solve by getting a polaroid sheet film back and a big
box of type 55 pos/neg film! Expensive, but saved my ass. Impressed the head of
the program for refusing to give in or give up on getting usable images.

A while back, there was a discussion of lenses yellowed by radioactive
elements in their glass.
(I don't have it with me, on my laptop - sorry.)
For those interested in the subject, a very detailed article has popped up on
Petapixel. More on the subject that most of us will ever want to know.

Enjoy!
