The goal here is to explore VueScan's infrared cleaning and grain reduction features. We begin with a 10+ year old slide on Fuji Sensia 100. The image won't win any awards, but it works for this test.
The scans were done with a Plustek OpticFilm 7600i via VueScan 9.0 on a Mac. The important settings were as follows.
|bits per pixel:||48-bit RGB|
|output colorspace:||ProPhoto RGB|
|infrared clean:||varied: None, Light, Medium, Heavy|
|grain reduction:||varied: None, Light, Medium, Heavy|
Once scanned, I batch processed the TIFF files with Photoshop as follows.
It's been reported that this scanner has a true resolving power of 3250 PPI. This is why I down-sampled the images. Apparently, the scan needs to be done at 7200 PPI to get true 3250 PPI.
