Can you tell me what this is?

I'm not sure if this is Camera related or processing.
I ran a test roll through a Nikon F with 50mm 1.4 using Walgreen's ASA400 color 24 exp.
The first shot 1a and the 10th shot have this spot on the neg,the rest look fine. Any thoughts or conjectures.

I have been guilty of using Walgreens for the past several years and they are not inspiring for either film or processing. I wonder if their minilab somehow exposed the film to some light. I've not had this problem but twice in the past few years I've found a negative with a small hole in it. I've started using Precision Photo. Much, much nicer. Joe

I don't know what it is but I suspect faulty processing, not a camera problem. I'd shoot another roll and send it to a different lab.

I don't think its camera since its in the middle of the frame, almost exactly the same mark and skips frames.

Just a guess that its a lab issue. It could be flaws from manufacturing but that's rare although I have seen some crazy stuff that was due to manufacturing goofs. I've seen Kodak totally miss the yellow dye coating on a batch of 8x10 E6 and seen daylight marked paper spooled on tungsten balanced 120 C41 film. Also seen the wrong film loaded in the wrong 35mm cassettes. It is possible it was light struck when manufactured.

The processor was Mikes Cameras in Sacramento.Most Walgreens here stopped local processing.I bought the body for the black prism at a good price and figured to sell the rest for parts, so no real loss.

That looks like a crease on the film. If it is it should be obvious on the negative.

I'm not sure how that could happen though.

I was not unhappy when the local Walgreens stopped processing film, as the screwed up every roll that I ever trusted them with.

Do you have a filter on your lens? Could it be a reflection?

No filter.I was thinking flair but had hood and sun was side lighted

negs are flat no crease.

frame 11a

frame 11a

frame 11 different angle from 10a so flair would not be the same.
I did notice small light area in 10a closer to the bottom also.

One thing to do with leaks is to lay the film in the camera as if you were taking the original shot. Emulsion side to front, upside down. In your case, also take the frames with the marks and put them to both sides of the the film gate. Maybe the leak is happening when the film is before or after being exposed. Look for any missing scews, rivets, etc. Sometimes there is a leak but takes the right combination of sun angle, and maybe pressure on a camera part, to make the leak have an effect.
