First of all, that is contradictory and a damn lie, since optical density and dynamic range are not at all the same thing! In recent publications, they claim more correctly Dmax is 4.3.

The original technical specification for ArtixScan 4000tf (a pdf file) claimed to have a Optical Density: 4.3 dynamic range. It is very important to optimize the lamp intensity, which can be done from within SilverFast. So now everything seems to be reasonably okay as far as monitor profiles is concerned. The 2.7.7 version of PhotoCAL corrects a very serious color cast bug in 2.7.6 (reported by me), and version 2.7.6 in turn corrects a minor white point problem with version 2.6. , but for the sake of simplicity, I will sometimes use the product name Photoshop in place of any of these applications, or simply say "our image application".Īs for monitor calibration, I use a 22" Mitsubishi Diamond Pro 2045u calibrated with PhotoCAL 2.7.7 from ColorVision, using gamma 2.2 (Windows users can therefore rest assured that this will give the same appearance as on a calibrated PC, despite this is a Macintosh). For studying the results, just about any imaging application can be used, such as Adobe Photoshop, Photoshop Elements, PaintShop Pro, Canvas, Gimp. Besides a target from Kodak (Q-60E3), which I will not use here, I have an IT8.7 target made by Wolf Faust from.

The film scanner used in these tests is a Microtek ArtixScan 4000tf, and the scanning software is SilverFast Ai 6 (version 6.2r3 was used in these tests) from LaserSoft Imaging ( ) connected via FireWire to a computer running Mac OS X 10.3.

The rest of this page assumes you have already acquired a fair amount of color management knowledge.įor the latest findings, see an update to this article. The original page discusses several tests done at different gammas. The whole issue of color management, profiles, white points and rendering intents is so complicated that I defer some of its intricacies to a page dedicated to: profiles, relative/absolute white points, rendering intents. In addition, at that time I was not aware of the importance of the order in which you apply curves and convert to a working space, so some conclusions are more accurate in the current set of pages. Also, the IT8 module in silverFast may have changed somewhat since then. However, it is not so easily digested, and the most important information is reproduced in the new pages. The first experiments were published in, and to some extent, that page is still relevant: the original article!. The conclusion is that inCamera is capable of producing good profiles with full range slides, whereas SilverFast profiles destroy shadow details beyond rescue and creates new really nasty color casts! The quality of profiles generated by SilverFast Ai 6, inCamera 3.1 and Scarse 0.3 are evaluated, and examples of results for a portrait and a particularly problematic image are shown. This page is devoted exclusively to problems when attempting to profile a professional-quality 35mm film scanner using an IT8.7 reference target and the scanner program ' SilverFast Ai 6' from LaserSoft Imaging.
