![]() ICE Scratch removal available, as well as Multi-Scanning for greater accuracy in the bit-depth.įor an interesting example of just what the ICE scratch removal does, take a look at both of the Noritsu images below and see the difference with ICE on and off. 36 bit color depth in original scan can be imported as 36 bits into programs such as Photoshop that supports higher bit depths, or converted via A/D convertor to 24 bit. The Nikon LS-2000 is a high end desktop scanner that gives 2700 ppi Resolution from a 2,592-pixel monochrome linear CCD. General Notes, Impressions, Opinions, Observations The Nikon LS-2000, one of the most advanced scanners hardware and software-wise, has an extremely difficult to understand software interface. Others, such as the Polaroid Sprintscan offers much more sophisticated controls such as curves adjustment for individual color channels. ![]() Surprisingly some of the most expensive and high-end hardware has the least control, such as the Kodak RSF 2035 which only offers gross color correction and overall brightness and contrast adjustments in the prescan dialog. It is here that the data contained in the final file must be optimized. Scanners tested by members include the HP Photosmart, Microtek ScanMaker 35t Plus, Kodak RSF 2035 Plus, Minolta Quickscan 35, Nikon LS-10E, Nikon LS-20, Nikon LS-1000, Nikon LS-2000, Polaroid Sprintscan 35 ES and the Polaroid Sprintscan 35 Plus.Īn overlooked but very important factor in scanning is the control the operator has during the prescan dialog in the software. ![]() These particular astronomical test subjects provide a very difficult test for both the scanners hardware and software as detail in astronomical negatives can lie just barely above the film background noise, as well as extremely dense detail in the overexposed core of bright objects. ![]() Different test subjects were used, including a resolution test chart, a standard color negative, a difficult high contrast Technical Pan astronomical negative, and a color astronomical negative. This is part of a test of various scanners used by members of the Astro Photography Mailing List (APML). ![]()
