Any thoughts on what this might be? My guess is damage from an x-ray (it ran thru a few times) but I'd love your thoughts. This is Portra 800 pushed 1 stop so I understand I was definitely pushing my luck with x-ray exposure. This was the 3rd roll I shot with this new (to me) camera and had great results on the first two. I had a similar spot on about half the images out of this roll. I guess the reason I'm not so sure about the x-ray issue is that the spot seemed strangely consistent to what I would expect to see from x-ray? Similar spots/colors and shape on each shot. Is that what x-ray exposure would look like? Thanks for any advice!
