Film Scanning
Back to Alex's photo page.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.
| resolution: | 7200 PPI |
| bits per pixel: | 48-bit RGB |
| slide vendor: | generic |
| slide brand: | color |
| slide type: | slide |
| color balance: | neutral |
| 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.
- convert to profile sRGB
- change to 8 bits per channel
- reduce image size to 50% (3600 PPI)
- crop out a 600 x 400 pixel detail
- save as JPEG at quality 8
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.
