I'm getting an issue with my V500 which I just can't explain.
I tried to re-scan some negs from last winter, but the images I got considerably worse, they're much blurrier and less sharp compared to the scans from the period just after the development in january.
I know this flatbed is not a high-end scanner but I always got reasonable results good enough for web archival.
After some researches I found out that this can be haze depositing on the scanner glass, so I tried to disassemble the scanner and cleaned it but nothing changed.
The settings I use are always the same, 3200dpi and medium unsharp mask, if someone could help me I would be very grateful
