what would cause this?

[mich8261]

Taken with M2 and ZI 35mm/f2; I might have had a green filter on. This is the only picture with this camera that has ever shown anything looking like light leak. None of the images before or after this one on the same roll have any such aberrations.

Thanks for looking.

Does the fog extend outside the frame on the film?

Pretty strong side lighting so I would guess lens flare. Maybe?

Similar to a light leak... the one below was caused when I opened the bottom of my M7, umm without rewinding the film.

the ZI 35/f2 does have a pretty bulbous front element and I do not have a hood for it. The shadow across that gentleman's face shows the sun to be at a perpendicular angle to the camera, so light could have gotten in that way. I'll also have a look at the negative to see if the streaks extend outside the frame, but wouldn't "outside the frame" show up as white on a negative?

Streaks like this would show up as dark on the negative. Clear areas of the negative "print" as shadows and dark areas block the light so they "print" as highlights. I'm sure there is a better way to explain but... Nice London shots BTW.

You have light leaks

You have light leaks

but why has it shown up on a single frame over several rolls of film taken in the course of 2+ years?

of course! I was thinking the opposite. The two streaks do extend outside the frame, but only about half way into the between frames area. I checked the curtain with a powerful flashlight, including advancing, and I can't see any leaks. And thanks for the comments on my London shots. I enjoyed the trip and now I'm enjoying the shots I took.

This is a light leak, not flare. Possible sources: lens change while shutter not completely closed (you have an M2: shutter travel _is_ horizontal), shutter brake failing or separation between the leading metal edge of the shutter and the cloth curtain (can happen with time). I would shine a flashlight through the front of the camera with the lens off and view from the back with the door up. Move your eye around with the camera between you and the light and see if anything is getting through. If this were the first picture on a roll, I might also suspect the felt light trap on the film canister.

I had to have Sherry Krauter replace the shutter curtains on my M2 after the cloth shutter started to fail. Then had to send it back when the metal leading edge of the shutter pulled away from the curtain. These are 60 year old cameras now and this sort of failure is to be expected if the shutter has never been replaced (or even if it was replaced 30 years ago).

Your camera is leaking light. Or it is frames from the beginning of a fast film where you have been too careless not seeing to that the film must be kept in the dark when changing film. - It could be that simple.

 

[mich8261]

this is frame 24 (of 36), so I think the lens change hypothesis with a small leak probably makes the most sense. How much would something like this cost to repair?

 

[Rob-F]

I also favor the light leak explanation. It really doesn't look like any flare I have ever seen.

 

[payasam]

Michel, perhaps the least expensive repair will be by Youxin Ye, wye7 AT yahoo DOT com. At most you will need both curtains replaced.

I had a similar random light leak some weaks ago. they happened without lens being removed ... The explanaion was curious and cheap! I had lost the little plastic part that protects the camera from the strap. The light, in some unlucky situations, entered through the little hole that was now open and caused very similar light leaks. This ocurred in some random (very very few) images.

Hope it helps.
