Film borders very washed out

Image Editing Help
1

Hey everyone,
Am hoping someone might me able to tell me whats going on with these images.

On a few of my scans, im noticing that the borders of the images are incredibly faded. Im trying to work out if this is something that i am doing wrong throughout the scanning and conversion process, or if it just an unavoidable side-effect of having a poorly exposed image.
When metering these images i was unaware that the ISO on my meter was set incorrectly, causing the images to be poorly exposed. I also had some occasional light leaks with this cameras film back, so that may also be a contributing factor.
I am DSLR scanning and at first i though the film holder was leaking light around the side of the negatives during the scanning process, but after some testing and messing with the mask on the film holder im fairly confident that that is not the case. Also being the fact that this was only happening on these 3 incorrectly exposed images, i thought i could rule that out.

Any help would be greatly appreciated. Thanks!

To me, these look like classic light leaks during the scanning process.
What does your set up look like?

If the camera has light leaks all bets are off regardless of how robust the scanning set-up is.

It’s possible your scanning light source is reflecting off the edges of the film holder. This can cause extra light to hit the edges of the film next to those sides. It looks like the overexposure pattern is pretty consistent on all the images. You could try scanning a neutral density filter or some other known translucent film with no image to see if it show up. If it does, that would point to the light source or the scanning film holder.

Having said that, it does look like it might be the original film back.
