This may be what you are thinking of: "There is no scaling or color correction of the raw CCD data in the scanning step. Some scanners either always or sometimes convert 10-bit or 12-bit CCD data to 8 bits before transferring it to VueScan, and then VueScan converts it back to 10-bit or 12-bit CCD data. This is done using a gamma correction table (gamma 2.2 with a linear segment as specified by Rec. 709)."

Vuescan does something to the CCD | data (I forgot what exactly, but it is in the help file). | | As for the Nikon device profile: The only place you can use it is in | Photoshop opening the raw scan and assigning the device profile in the 'missing | profile' dialog. Vuescan uses its own version while scanning, not a custom-made | one. And after the image comes out of Vuescan, you don't want to assign a | device profile anymore, but rather use a working space profile. | | Barbara Nitz | | | -- | GMX - Die Kommunikationsplattform im Internet. | http://www.gmx.net | |
