So I have shot a great deal of black and white film through my IIIa now, and develop it myself. And I love it. To make a long story short my first roll of colour through it, and have encountered a problem. The roll was 800 speed fuji colour, c 41 development. Anyway I took it to a local ritz for quick development. out of the 36 exposures there are a handful of shots with a strange rectangle on them. Im not sure what it is from. I was using two lenses, a 35mm nikkor and 50mm summicron "yellow glass". Now these are the only lenses I have and I use them al the time, and no problem with black and white. which is why i think this is a development problem, but its not consistant on every neg, only a handful. any ideas? sorry for the long explination. below are some examples.... the first two have the oddity, the last is from the same roll. Thanks for any imput

Does this "rectangle" appear on the negatives too?

yes, its on there. so at school we were debating over odd flare, or processing. The thing is I remember which lens I was using and it appears on either or, but its not consistant.

Do the affected frames appear following a lens change? With some shutters, a lens swap in bright light will fog the frame that is behind the lens at that time.

Looks like fogging from some sort of light leak.

The more I look at them in bridge the more I think that is what happened. I was just puzzled since ive changed lenses before and never had this problem. Thanks for the feedback everyone

do you use a lenscap walking around?..
It looks like light comes throught the lens when you are not shooting or changing the lens...the shutter should be fine...
The old cameras do not like permanent light, because of the "open" way to the shutter ...

The lens caps are always on while im not actually shooting. Im surprised to hear about a problem from switching lenses since Ive never had this sort of thing happen before. I shot very much the same and did nothing different this day. Ive got another roll of colour from this day that hopefully ill get developed tomorrow, from a different place, to see if it was just a fluke.

this happend in the camera .....
My english is not so fine to explain it well...:bang:...
The light comes behind the seal of the shutter...you see it is not the entire frame it is more inside!...I know this from cameras...you can control the camera if the space between the seal and the shutter is to much..

I had a Wetzlar M6 that did this, only happened to the last frame in a sequence (ie, the frame of film that was cocked and ready to go for the longest period.... hours, days, etc. -- long enough for the fogging to become noticeable) A respected Leica technician in the US could not find the source of these "Leitz leaks" so I ended up getting rid of the camera. Good luck.

Jim N. is almost certainly right. I had this problem with a IIIc whenever I changed lenses in light. Turned out to be a leak around the bottom light shield. Nothing to do with the shutter.

Was the b& w you were previously shooting also 800 ASA ?
The 800 speed film might be more susceptible to fogging during lens-change.
I usually shoot 400 Fuji color outdoors, 800 for indoor/existing light.
I have changed lenses outdoors and don't recall having had this happen... the camera instructions do recommend avoiding lens-change in bright light...
Right now I have Fuji 1600 in my black 1933 III, I was shooting exisiting light at a banquet; I have to finish-up the roll, I may take it outdoors and see how "tight" the Barnack is...

The black and white was always 100 Tmax, or 1600 neopan for subway and night work. These shots below are 400 Fuji that I shot on the same day but after the 800. I took this film to Photo lounge, and not a problem at all. Its the same location as the one image of the house. I changed lenses here and there was no problem. Ill do another experiment with black and white and change lenses frequently outside again and see what happens. Thanks for everyones help

You'll be glad to know I had this same 'problem' with my IIIa. Some of the photos taken directly before I switched lenses had a slight fog similar to yours. I now make sure I change lenses in the shade.
