Is this a lightleak?

clineco · Dec 21, 2014

Hi -

I'm testing a new (to me) back for my Rollei SL66 I'm getting something on the negs...I'm not sure if they are lightleaks or what they are. Anybody have an idea?

edit// I also added another attachment. This one shows some wierd vertical banding across the top of the neg.

Taping the crucial areas and exposing another roll should answer this question.

good idea. I'll try that.

In a Hasselblad light leaks come in on the left side of the camera where the darkslide is inserted and the light lands on the right side of the negative. Since the image is inverted the light leak appears on the left side of the print or slide. That is the artifact of a bad light seal in the film back. Therefore you light leak appears on the darkslide side which seems counter intuitive.

I hope that helps you.

Ok. Just ran another roll. I taped the heck out of the back on all sides and over the dark slide opening. The faint vertical streaks seem to have disappeared (film is still drying though) but the heavier artifact that spans the top of the neg is still apparent. Other ideas?

A scratch?

It's on all 12 frames same pattern. So it's not a scratch. I'm really not sure...what the heck it is.

internal reflection of some sort, perhaps?

I was just going to suggest that.

Since it doesn't seem to affect the film borders at all, it has to be coming from the between the film gate and the lens. I'd check that the mirror is going up all the way, and that there's nothing shiny in the body or on the interior parts of the lens mount.

Along with a light leak, could it be a crease? That was my first thought.

It's difficult to tell from the two different pictures, but the heavy line at the top looks to be the same. Can you confirm the horizontal line is nearly identical on all frames?

Load a roll, advance to frame one, put on lens cap, pull slide out. Use a very bright flashlight and shine into every nook/cranny on camera/magazine (slowly, a flashlight is not nearly as bright as the sun). Fire shutter with lens cap on, advance to frame 2, finish roll normally, develop. Carefully examine first frame and see if artifacts are present. If there are artifacts, you should be able to determine where the light is entering the camera. If the artifacts only appear on frames 2-12, the problem is not a light leak in the magazine/camera but perhaps an internal reflection/shiny baffle or other problem.

Ok. Figured it out. (thanks to this thread)

There is a black strip of metal just inside of the shutter opening which is causing a reflection. I held a piece of tracing paper to the open shutter and it was clearly visible. Now I just need to figure out the best way to remedy this. It is odd, I can't imagine these cameras were shipped this way, maybe sometime over the last 50 years my camera got a shoddy repair job?

That looks more like mishandling of the film during loading on the reel. It looks (to me) like the edge was bent while loading on the reel. Large roll film (120) is far more difficult to load without wrinkling/bending/buckling than 135 film. It can be challenging to learn how to control a gentle uncrinkled curve while loading 120/220 rollfilm.

Very odd. I just looked inside mine (SL66se) and it has the same sort of metal strip, but it is painted with the same very-matte-black paint as the rest of the body interior. I would think some careful work with a brush and paint could solve the problem.

Christopher Walrath · Dec 30, 2014

Yeah, I do not see light leak as it is not uniform. I do not see mishandling as it is the same throughout. I think you are right on the reflection. Mike is right, painting would be best but a black Sharpie would do in a pinch until you can be sure to take the time and care of applying a coat or two of some flat black to that metal.

I'm curious if my camera is unique to this issue or if others have ran into this problem with the old SL66 cameras. Mine is a 1966 version so it may have been an early production error...

I would say this is your answer.

Yeah. That's the plan man.
