Howdy, all!
I’ve gone through numerous different scanning setups, but ultimately settled on a Minolta Bellows I with Slide Copier kit for a good deal I couldn’t pass up, plus I’d already had the Minolta 50 f/3.5 Macro lens and associated 1:1 adapter.
I’m using this setup paired with my Canon R5, but I’ve run into a consistent issue with lighter/yellow edges on B&W and color film, respectively. Now, on the B&W it’s easy enough for me to fix in post, but it’s a nuisance and it’s downright impossible on color. I understand that this issue is caused by uneven lighting, or the mask of the film holder (in this case the copier mask) causing a shadow. My lightsource is an Aputure MC, and I’ve tried with it right up against the copier, as well as different distances away with basically the same end result of wonky edges/colors.
It also doesn’t help that the copier portion itself isn’t sitting parallel, so my exposures are also slightly crooked. I’ve tried just about everything to resolve this with no luck. This may be a sign to look into another bellows setup, or 3D printed holder with backlight with the camera back on my copy stand. The bright side is the bellows will give me the granular focusing control I was lacking in the past, so it’s not all bad.
The photo depicts the skewed positioning as well as the sides being fouled by the mask. I was going to post a second photo, but can’t in a single post due to new user limitations.
