The noise that occurs at random in a single sample scan can be reduced by taking multiple samples because such noise will not occur in the same places between different samples. Using multi sampling on color negatives is generally beneficial since the darkest areas of such transparencies contain a lot of important detail while any dark areas are especially prone to noise. You can specify this under the 'Number of samples' option which is only visible if this feature is available for your hardware. If your scanner supports multi sampling that may be used to further improve the scan's quality where needed. In the example screen shots a Nikon Super Coolscan LS 8000 is used which is able to scan at 4000 dpi. When scanning for archival purposes it is recommended that you use the full physical resolution your scanner is capable of. The resolution of the scan is also being defined on the input tab. Set this to '48 bit RGB' which equals 16 bit per channel. Then select the required bit depth which is controlled by the setting 'Bits per pixel'. a daylight scene shot on tungsten film without filtration or vice versa. When scanning slides this mode could also be beneficial when scanning film with noticeable color casts.

If you are not using the advanced techniques of exposure control or analog gain detailed further down on this page you should choose color negative as your medium for negative scans. Since Photoshop actually uses only 15 bit plus 1 value precision instead of the full 16 bit range used in a linear Tiff file that kind of scaling can be beneficial. The difference between the two modes in combination with RAW scans is that for color negative mode the three color channels of a scan are being scaled up using suitable factors to ensure that all of these use the same range of values. To create suitable scans you first have to select the input tab and to choose either slide or color negative from the media pulldown list.įor both choices a negative is preserved as such in a RAW scan's linear output file. Hamrick Software's VueScan Professional is very well suited to create linear scans of slides and negatives since the professional version of VueScan features a special RAW output mode.
