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.
Important!
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
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.
