Massive Vignetting...Please Explain

[Bjorn Nilsson]

Been thinking a bit about this.
Try to recapitulate what you did and how you did every step from loading the film, through exposure etc. until they were developed.
We don't mind if you "jot it down" into an answer here, so that we can help you pinpoint the problem.
One thing, as you say that every negative looks the same. Are they exactly the same? Did you at any point, e.g. while unloading the cassettes, stack them up before loading them into whatever you use for developing? Etc...

Need to know if that is the negative or the positive which you're showing.

I should have made this clear...sorry.

What I've posted is a scan of the negative. I have no wet darkroom, so this is not an enlarging problem.

I'm pretty sure what I'm seeing is a result of my cobbled together lens mount. The camera has a copal 1 hole and the lens is copal 0. I made an aluminum donut to reduce the size of the hole.
Anywhere I touched something seems the most logical place for there to be a problem, so that's where I'll try to fix it first.

The good news is, the part in the center looks pretty good (this one from another negative).

Hmm, Graffiti in B&W is surprisingly appealing. Nice shot.

Where's GPS? The sky didn't fall as predicted.

I think you've got a nice camera.
