(And as all the other images here, it is converted to 8 bits/channel sRGB and jpg'ed at quality setting 8.) This image is scanned in SilverFast Ai at gamma 2.0 with the setting '48 Bit Color', and it is color managed by SilverFast using a profile created by SilverFast, which converts the image to the standard working space Adobe RGB (1998).
It8 target vs. mac os x#
Tests on a Mac OS X system shows, however, that the appearance of these images in Safari (1.2.4) is precisely the same as the appearance in Adobe Photoshop!Ĭlick to see a larger version in a separate browser window (120 kB). Your browser may or may not understand the sRGB profile that is embedded in the images, so to be on the really safe side, you need to download the images to disk and view them in your icc-aware image application. The fact that they are in 8 bits/channel sRGB and jpg-compressed might have you suspicious, but when a scanned and profiled IT8 Fuji film target is converted to sRGB, the only colors that change significantly, as seen on a calibrated CRT monitor, are the area F3–I4, the area F7–H8, G12, and the pale patches in area A13–A19. Downsampling to small thumbnail versions is done in 16 bit mode. Then they are converted to 8 bits/channel and jpg-compressed with quality setting 'High' (8) in Photoshop. The conversion engine is Adobe (ACE), but tests confirm that the difference between this engine and e.g Apple CMM is very small. Just prior to saving these images in a web friendly format, all of them have been converted to the sRGB profile, using the relative colorimetric rendering intent, and the profile is embedded in the images. The setting in SilverFast called '48 Bit HDR Color' is the setting used when you want as "raw" unmanipulated results as possible, usually at gamma 1.0 and usually with no embedded color profile. The setting in SilverFast called '48 Bit Color' is used when you want SilverFast to handle color management, and, if you like, other manipulations.
