another RB leak

[Wayne]

I think I've got one back sealed up well (though I haven't tested it in really bright sun like I tested this one), and I replaced all the seals on my second RB Pro back. But this is what I got. Sorry, I just slapped it on the all-in-one, its not a proper neg scan. But I don't see anything wrong with the seals I installed...

Try to imagine which way the negative sits in the film back.. upside down, dull side to the lens. Then take another look where the light leaks are relative to the back?

Check, the dark slide baffle. Also see that the plastic face plate screws are all taught. Corners are new? Latch side is the right thickness? Door strip is the right thickness? The shell is not deformed?

I'd also try in a dark room, the bright light inside the camera trick. Inspect the sides very carefully at all angles. If light can get in, it will also come out.

I went through it this afternoon after posting, and held the film up to the back to see how it was oriented and how that relates to possible leak areas. I now believe the leak is coming from where the foamed corners of the film carrier meet the closing latch side of the back. I did not replace those corners because they looked OK, but now I will. They may be compressed. I will also try the light inside the camera trick, I haven't tried that yet. Thanks
