Hi guys, for details my scanning set up is a skier sunray copy box with 120 and 35 mm inserts. I’m having trouble with some of my scans I believe this is a result of vignetting from my lens. I have a nikon 55mm ai macro lens attached via converter to Fuji Xt-2. Perhaps the converter is the issue (K&F converter)?
I trying to get flat field correction working. For some reason I get these weird textures appearing after I complete flat field correction in lightroom.
Here is an example of the textures:
If anyone can give me any advice as to what I might be doing wrong I would greatly appreciate it. For reference I scanned all my negatives. Then I removed the film holder and shot an image of the source light. I focused near to infinity so that the frame was out of focus. I’ve also tried making it out of focus in the other direction (i.e. focusing too close).
No idea what the issue is here! Thanks
