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. [...]

SilverFast Multi-Exposure (Dynamic Range)
September 7th, 2009 · No Comments · Photography, Scanner, SilverFast, analogue photography
IMPROVED: SilverFast Multi-Exposure (Dynamic Range)
Using Multi-Exposure the original gets scanned serveral time, but with different exposure times. By taking these single scans into account the software calculates the final HDR-Scan. This technique increases the scanner’s effective dynamic range (contrast spread) considerably, saving details especially in the light and shadow areas of an image. The EDP [...]

IMPROVED: The SilverFast Kodachrome Workflow
Kodachrome slides are very challenging to scan – but not with SilverFast.
The usual bluecast is omitted by using Kodachrome ICC profiles and by calibrating the scanner with a new developed SilverFast Kodachrome IT8 target. Multi-Exposure increases the scanner’s dynamic range to prevent any details from getting lost and the improved SRD [...]

IMPROVED: SilverFast iSRD (dust and scratch removal)
While scanning a slide, even the smallest scratches and dust particles become aberrations, that can’t be ignored. Some scanners feature an additional infrared channel, which’s data can be used for defect detection and elimination. The SilverFast iSRD dust and scratch removal works fully automatically or can be adjusted manually [...]
