Zeiss Super Ikonta !!! Exposure Problems

My first roll of film w/ my Super Ikonta III showed some interesting exposures. The left half of the negative

seems to be way over exposed. The right half of the negative looks fine. If this were a Leica I would say it was

the shutter, but obviously ( I think) that wouldn't be the case w/ the Ikonta's Synchro Compur shutter. Anybody

hazard a guess? Mt first thought is that it's a light leak. The bellows shows no problem. Odd that it would be

just the left side w/ a light leak though. Maybe something w/ the transport mechanism or pressure plate?<div></div>

Is that through the entire roll? It looks as if the roll was somehow slightly exposed on one side. You might check for a light leak in the back.

Mike,

It was through the whole roll, except for one or two shots. I sent the film to a lab for development, but I can't see how they could have done it. It has me stumped.

I'm beginning to suspect it was the lab. I gave them a roll from another camera w/ 120 film and I just noticed that one of it's negatives has the same thing, but it's just messed up on about 1/4 of the width of the neg. I also have a long scratch from end to end on some of the negs. Time to find a new lab.

I've had this kind of thing happen at labs if they don't load the roll correctly. Shoot another roll and take it to someone else and see if it's good. Also if you're just shooting B&W why not develop it yourself, it's very easy.

It's possible (I've had it happen) that you have a light leak on the side of the body where the front half meets the back half. The two shots that didn't seem to have it were shot that you might have taken in rather rapid succession and were not allowed to be exposed to the leak for any length of time before being rolled on and covered with the paper backing. If you had taken a shot and either let the film set idle before the next shot or advanced and let the film set idle the light leak would have time to work on the crystals. By the looks of it I'd say the leak is very slight, but I could be wrong. It's worth checking out. I know the early Super Ikonta's were built like tanks, but the newer ones were made of more stampings and might be more prone to misalignment. JohnW

I've seen that effect when a tank with reels was not filled completely, but in that case the effect was "top and bottom" not "side to side".

 

If the lab is running the film through a machine, then the machine could be stopping and starting, or otherwise varying speed, as it transports the film. Maybe they're missing a tooth or some teeth on a gear in the transport mechanism.

Disregard my response above. Stupid me! I don't know what I was thinking, but I had been up for just toooooo many hours when I wrote that response. Pretty bad that I didn't think to look a little closer, but now I'm even a bit puzzled. It still could be a light leak, but very well could be uneven development also. I like Mike E's suggestion above of running your own film through some soup to see if it's the camera or the processor.
