Hello,
I posted a photo in the Technical Gallery asking if anyone could comment on what went wrong with my photograph but nobody has commented there so perhaps it has not been seen. The camera is a Zeiss Ikon Super Ikonta IV. A folder with a Synchro-Compur shutter and a coated Tessar lens.
I have only had the camera a few weeks and now I have shot perhaps 10-12 rolls of film. Initially I thought the problem was some kind of vignetting or lens flare caused by a slightly loose lens hood but now I have noticed it without the lens hood. It only seems to occur in bright sunlight (I do not mean trying to shoot into the sun).
This effect occurs in about 1 or 2 photographs per roll (of 12). It is always in the same place, a the bottom right of the negative. I have had a look in the dark with a torch and I cannot see a light leak and I have also looked through the lens from the back on bulb and I cannot see anything obviously wrong. The shutter does not seem to stick in any way.
Could this be a sticky shutter blade that is opening properly but being slightly slow in closing? Or is it an pinhole in the bellows? I would be grateful for suggestions. If necessary I will send the camera away for some attention as I love using it and it is in wonderful condition generally. I do have a friend who can easily time a shutter using an oscilloscope and phototransistor gizmo but I am not sure this will help as I have not seen evidence of poor shutting timing in terms of over/under exposed photographs.
I attach one photo showing this flaw in the bottom right of the picture. If it helps I can post different pictures showing the same issue.
I was out shooting yesterday as well and in 3 rolls it occurred twice (2 were infrared, 1 normal B&W). It was fairly bright sun the whole time. If it is not a fault of the camera but a problem with me I would like to learn what I am doing wrong.
Best Wishes,
Stephen
