I had a problem with some kodachrome received recently too. Some slides showed a very distinct part(like 1 stop underexposed) across some of the slide.

here's an example. I was using a fill flash, and I know that the shutter and sync is working properly, and 80% of the others don't show this problem. Does Kodachrome have to be re-exposed in the processing?



IDK if this could have caused the problem.



please forgive the dollar signs. my scanner software is a demo !!!

Do you have others you could post? I'm trying to look at the ambient vs. background but it looks like the natural shadows fall in roughly the same area as where the line is so it's hard to tell if that was a mechanical error in your camera or something with the processing.

Yes Kodachrome does need to be reexposed but AFIK the lights are all colored to develop the different bases, and it is reexposed in between the development stages of different layers of the film (develop, expose, develop, expose...). So I would expect a reexposure error to have a heavy color cast.

Also, what kind of camera were you using? Were you using something with a vertical traveling multiblade shutter or a side curtain shutter like a Pentax K1000?
