Canon 5d Mark iii. April 16th 1_2_3 build. I was using the x3 crop function to shoot some owls. All the x3 crop stuff looks killer. I turn it off and shot normal and I got these tiny vertical lines in the "bright" section of the image.
It may be in the dark parts but I can't see it. I cranked the contrast and darkness in the frames so it sticks out more but i tried grading this and it ends up looking like compression artifacts in the video once exported to ProRes. Any ideas? It did not appear to be the "banding" issues i can find by searching. Two stills attached. Again, x3 crop looked fine. regular 1920x1080 raw resulted in the lines. I used Raw Magic to process these to DNGs
Look for the lines in the blue sky
No lines in x3 crop version
