Select "Transparency" for scanning slide positives, Kodachrome images and negatives, either framed or on film strips. (Transparency is found by clicking on the "Reflective" icon and selecting from the drop down menu. Kodachrome and Negatives are found by clicking on the "Positive" icon.) For transparency scans on a flatbed scanner, it is important to remove the cover of the transparency unit. On a pure film scanner, it is only possible to scan transparent material and the Reflective mode is not available. On some film scanners, the film holder type can be selected in the software instead. Next, select either positive, negative or Kodachrome the "Kodachrome" setting being reserved for the SE Plus and Ai Studio versions only). "Positive" is the setting used for the normal positive slides. Select "Kodachrome" for the special slide film from Kodak - often identified by the "card frame". The selection automatically loads a special color profile which prevents the usual blueness that Kodachrome images would otherwise acquire when scanned without this special feature. If you have selected the "Negative" setting to scan your negatives, the Negafix dialog will have opened simultaneously as an additional tool. In the Negafix dialog you can choose a film from a wide selection of manufacturers and different film typed with different ISO values. This ensures that the orange mask of your film strip is correctly removed during its transformation from negative to positive. If you film type is not listed, select a similar film type or use the standard profile: When using our HDR and HDRi raw data formats, this information is saved for later processing. In the Expert section of the dialog in Ai Studio, you can also edit the profiles or create your own profiles. Open the dialog's Expert section by clicking on the mortarboard. Select the color depth as the final step before the preview scan. The color depth describes the number of bits per channel. Color images are comprised of the three color channels R(ed), G(reen) and B(lue), each with 8-bit data or 16-bit data. Black and white images are managed with one channel with 8-bit or 16-bit data. This delivers the different color depths that can be set in SilverFast. The greater the color depth the larger the resulting file. SilverFast displays the input values to the left and the output values to the right of the arrows. If only one value is present, the input color depth corresponds to the output color depth. SilverFast always uses the largest possible color depth that a scanner offers and also uses this for internal calculations. Depending on the SilverFast version, an output with 16bit per channel or with 8bit per channel is then possible. All versions offer 16bit for raw data scans, but only Ai Studio allows both 16bit raw data and 16bit for processed images.ฤก6-bit data provides a higher range of color gradations (65536 per color channel) in comparison to 8-bit data (256 color channel).
