Unexpected 'optical spots' on film

[AA+]

Edited to add test results: I gave the new bellows on camera both extended and retracted a lightbulb test. It performed properly.

Thanks for your good idea, Bruce ... Best wishes --- Allen

How do you transport your film to the lab for development? If you use boxes, could one of your boxes have a pinhole?

I use two different nested boxes for transport, film within cardboards, external corrugated cardboard box. If light hole, I would expect edge fogging. Thanks, Jason, for your question. Best wishes --- Allen

Are they always yellowish green like that? Are all of the surfaces inside the body flocked? Could some bit of shiny hardware inside be reflecting?

I have looked inside and not seen shiny hardware. Interior parts of camera are flat-black painted wood. Best wishes --- Allen

Frankly, at first blush it looks like developing, but I experienced the same set of perplexing problems, with somewhat different manifestation) without solution, until this.

Of perhaps greater concern is the unfortunate tendency of your camera to rotate portrait views into landscape oriented views .

Maybe they're from pinholes or cracks in the dark slides of one or more of your film holders (given the spots aren't always in the same locations) or perhaps some other light leak in the film holders.

Or since you mention cutting the film to size in your darkroom--might the spots be from static electricity discharge when working with the film? That seems a little less likely since the problem has a correlation to shooting in bright sunlight, but I'm trying to think of other possible causes that haven't already been discussed above.

Thanks for your ideas. It is a tough problem. Best wishes --- Allen
