Example 3




As with the two previous examples we're still NOT colour managing in our images. The absence of a scanner profile means that we have no way of describing the source colour characteristics of the image, and so these settings again correspond to the Photoshop 6, 7 and CS Assign Profile command. However, in this instance the embedded profile is the Photoshop working space profile. The choice of Automatic for "Internal -> Monitor" and  your Photoshop working space profile for Internal (Profiles for Image Colour Matching/ColorSync) means that we get an accurate preview. The settings shown example 3 are probably the best choice for users without the luxury of the SilverFast IT8 Calibration module or a custom scanner profile.


Example 4




The settings shown for example 4 indicate how SilverFast should be configured when we require a FULLY colour managed workflow.  The "Input -> Internal" = ColorSync/Image Colour Matching instructs SilverFast to use the IT8 calibration profile as the source with whatever profile we have selected in the Internal (Profiles for ICM/ColorSync) as the destination colour space.

Typically the Internal profile will be the same colour (or working) space as we selected in Photoshop The choice of Automatic for "Internal -> Monitor" ensures that the preview display accurately reflects how the image will appear in Photoshop and with the Calibration profile in place we are assured that the colours being displayed are a close rendering of the original. The "Internal -> Monitor" should be set to Automatic so that an accurate preview display is assured.

Note that with example 4 we embed the Internal profile or as it should more correctly be called our "working space profile" into the image. To avoid any ambiguity the Internal colour space profile is that associated with Photoshop and NOT SilverFast. In the example shown above I selected Adobe RGB (1998) since this is my preferred Photoshop working space. Given that we have a source and destination profile we describe these settings as being "similar" to the Profile to Profile command in Photoshop 5.x or Convert to Profile command of Photoshop 6/7 and CS.


The KEY point to note between example 4 and that of the previous examples is the impact of simply choosing something other than None in the Input -> Internal field. The Input -> Internal field is effectively the switch by which we turn colour management ON or OFF. None means colour management is OFF. ColorSync/Image Colour Matching means colour management is ON.


Example 5

NegaFix Special Case

A further enhancement introduced recently is that SilverFast will ignore the Input profile selection when the user chooses to scan negatives. The really neat thing about this change is that unlike previous versions of SilverFast the user need NOT make ANY changes to their default CMS dialog configuration. Choosing the setting shown in example 4 above and having set SilverFast for scanning negatives results in the Input profile being automatically disabled. However, in order that the SilverFast preview and Photoshop display of the scanned image are matched we should still ensure that our current Photoshop working space profile is set in the Internal (Profiles for ICM/ColorSync) field.




The above settings apply equally to 36 to 24 bit colour mode, 48 bit colour or HDR colour mode.
