Gran View...Getting Closer

[dazedgonebye]

Well, I managed to eliminate/reduce the massive light leak/reflected light that caused my big white tunnel effect. http://www.largeformatphotography.in...ight=gran+view

Now I'm still having a bit of a problem. Any ideas what that dark ring is about?

Excuse the crappy picture. I'm just pointing it to test.

What was the source of your previous massive light leak???

This looks like the normal vignetting of the ultra-wide lens..perhaps exaggerated by your scanner?

Perhaps you used a polarizing filter?

Two interesting blue squiggle lines running from the upper right side to the middle of the picture. Scanning error?

The light leak was my shoddy job of mounting a copal 0 lens to a copal 1 helical. On top of that, the flat black paint I used on the inside of the camera wasn't very flat.

No polarizing filter. The blue lines I placed there to show the area I am concerned about.

If it were just light fall off, it should get darker to the corners instead of just having a dark semicircle...right?

The sun was pretty much to the left of me. Could the darkness be internal reflections in the lens?

Did you use any type of filter?

Did you use any type of filter?

No, no filter.

Grasping at straws. How did you develop the negative? Alone? With other film? I'm wondering if this sheet and another sheet got too close during development.

[dazedgonebye]

Just one sheet in the jobo.

Hmmm, mottled skies are a classic sign of developing issues. Well, to be more precise, agitation issues. What developer did you use? Is it possible that it foamed up on you? Those blank skies are unforgiving...
