I’m scanning negs for the first time, my setup is
Nikon D750 + 55mm 3.5 micro + extension tube
Raleno led panel
Essential film holder
I seem to always get excess light coming in, usually on one side, no matter what I do. It’s more severe in 35mm for some reason but I still get it in my 120 scans. In the 120 shot just compare the left side to the right on the floor and you’ll see, in the 35mm scan it’s on the left and parts of the right too. I’ve tried to block off as much light as possible with no real difference, it could be excess light coming through the space between the frames but I’m not entirely sure. It doesn’t seem consistent with the lens vignetting though so I don’t think it’s that.
Any help appreciated, thanks!
