Auto-Sharpening function USM for SilverFast HDR and DC is now aligned to the scanner

December 25th, 2009 · No Comments · HDR, News, Processing, Scanner, SilverFast

The human perception is aligned to the recognition of edges and lines. So the sharpness impression of photos can be increased by contrast rise of small brightness changes. Conventional sharpening functions often increase the detail contrast of the complete image in general and therefore strengthen also any image interference of the original, details get lost. In contrast the SilverFast Unsharp Masking USM carefully raises the contrast at edges and lines. The sharpened images appear losslessly much more detailed.

With version 6.6.1r4 SilverFast saves scanner related information along with the image data. This allows an advanced automatic Unsharp Masking for the later post processing with SilverFast HDR, which takes the specific scanner details into account and is therefore able to produce brilliant, pin sharp images.

This innovation is a special advantage when working with the SilverFast Archive Suite.
