Odd light leaks

[RichyD]

I'm pleased with my latest acquisition, Franka Solida II with Xenar lens. Every frame though has wispy white lines running the length on either side and the top. I tried to find any bellows leak with a light and flash but could not detect anything. They are a little in from the border of the frame and usually cropped out but would like to fix. Would it come from the rear part of the bellows where it attaches to the chamber?

Also there is a leak onto the bottom edge of the film to the right, but this doesn't extend into the frame area. I guess this is coming from the door latch.

Leak number 2 is from my Super Baldax and this only occurs sometimes and is a red patch in the lower right of the frame. I am guessing this comes red window reflections but it is intermittent. One frame in the last roll, none in the one before, a few before that.

Any insight into these issues and how to resolve would be appreciated. I have attached two files but don't know if the resolution restrictions will show the defects clearly.

Thanks
Richard.

#1--I have this on a folder, I thought is was reflection from the metal frame that is near the film plane. #2 looks like a bellows leak but it is hard to see in the photo.

It's indeed hard to see with this resolution. Guess that with the photo of the Lifeguard house there were some problems at the bottom of the frame which could come from light sipping in during unloading of the film from the camera. Had a similar problem when one time the film on the take-up spool was too losely wound.
I also see some straight lines just inwards of the image frame. See this often in folders and guess that these are lightreflections from the bellows. With these types of camera it's good to allow for some spare room around the subject.

The photo from the (nice) car shows IMO indeed a reflection of light coming through the red window. Alas, i don't have experience with the Super Baldax but, in general, only open this window when it is somewhere in the shadow and close right after use. In strong sunlight it's also good to keep that area of the camera covered with something (tape or case).

Thanks for the responses. With case#1 I can see that it could be light reflected from the rollers. I was worried that it might be bellows related which would necessitate a repair. So I'm OK with that.

Case #2 is the more worrying as it impacts photos randomly. I always thought was from red window but have trouble working out how the light could get around to the film plane. The window slider can often slip open unawares with handling, say pulling it out of a bag; I have been very careful recently to only open it just to get check the final wind on.

The other possibility I just thought of is that the winding knob on Baldas is not spring loaded. Many times I have found it pulled out when I take it out of a bag, or sometimes happens on winding. Perhaps light is entering through the knob spindle when the itis pulled up. It had been giving a bit of trouble recently, not fully seating and not operating the frame counter. Cleaned it now and will try to rely on the frame counter AND not open the red window. See what happens.
