yesterday i was shooting a video with my Nikon d500 and a Sigma 17-55 f2.8. When i imported the footage i could see some red color on the snow. I attach 2 frames to show the case.
It's very subtle but I was wondering if anyone has had this problem or know what it's the reason. Is it the camera or the lenses or the setting?
I was shooting in Manual, with manual focus at 2.8 with a variable nd filter. The white balance was set on DayLight and all the other colours are correct so i don't think it can be the problem.
So hopefully someone could bring some info about the issue.
