I’ve tried everything I can, but dark photos always have this orange vignette. I block all the extra light from my light table, the light table was one recommended here in the forums, I disabled lens correction, I turn off all the lights in my room so there’s no ambient light and the exposure is quite fast. I also shoot the matte side of film. I’m using a Samyang 90mm Macro lens with the hood on.
I can’t think of anything else to try. The only thing left really is reflections from the lens? Any other ideas? It’s not too bad in these particular photos but sometimes it’s really distracting to have the corners glow
