Mamiya Six odd light leaks

[Yobo57]

Just got a roll back with my Mamiya Six folder and most pictures have these really crazy light leaks. Inspecting the bellows, it looks like some pinholes have formed, but I feel like maybe something else is going on too?

There’s three types of light leaks
1. In dark environments only: white ripples coming from the bottom
2. Large yellowish white rectangle taking up right two thirds of image. Only appeared in one indoor shot out of 5, but appeared fairly consistently in sunlight.
3. Thin scribbles of light in top right corner which I’m fairly certain are from the pinholes.

Two pictures in overcast/shaded areas had no light leaks whatsoever.

Shutter speeds are fairly accurate and all seems to work well. Any ideas?

May we see the negatives or transparencies themselves - backlit and with the edges and spaces between the frames please.

Hi Matt, I won’t have the negatives back until at least tomorrow but more likely a few days unfortunately. I can tell from the scans however that the light leaks definitely extend at least beyond the bottom edge of the frames.

That helps a bit, but scans add their own set of variables, which make it more difficult to diagnose these sorts of problems.

Alright, I’ll upload the negatives as soon as I get them back
