Part 1: For All FlexColor Users
Instant Approval Architecture
Gamma Slider Replaced by Midtone Slider
In FlexColor 4.0, the Gradations window featured a slider labeled Gamma , which
provided a precise gradation adjustment that lightened or darkened the image in a
consistent way that is compatible with color management. In FlexColor 4.5, this has
been removed from the
Gradations
window and replaced by a midtone slider in the
Histogram window. The function is the same, but this new control is more similar to
controls used in other familiar programs, such as Adobe Photoshop.
If you open an old file or use an old setup, the gamma setting will automatically be
converted to a new midtone setting that duplicates the effect of the old setting. For
example, the previous default gamma setting of 2.2 converts to a midtone setting of
1.20; this default matches the assumptions of the color profiles that shipped with
FlexColor 4.0. Note, however, that the new color profiles that ship with FlexColor 4.5
for both scanners and cameras are calibrated for a midtone value of 1.0; consequently,
all of the new setups included with version 4.5 use the new color profiles and are
preset with a midtone value of 1.0.
As a result of this change and other changes in the color-handling system for camera
images, you need to make some extra adjustments when you open camera 3F files
made with older versions of FlexColor (see also “New Color Handling for Camera
Captures” on page 19); scanner images, however, are not affected unless you change
the color profile from an old setup to use the new profile.
The Gamma setting from the Contrast tab of the Setup window has likewise been
replaced with the
Midtone
setting.

16.
Instant Approval Architecture
FlexColor 4.5 now provides full support for the Instant Approval Architecture (IAA)
system introduced with the latest Ixpress digital camera backs. Using this system, you
are able to assign one of three approval levels (green, yellow or red) to each image.
Consequently, FlexColor displays the approval level of each image, includes controls
for modifying approval settings and also enables you to use approval levels as criteria
when importing, sorting and filtering, etc.
Though the IAA system was primarily developed to enable digital photographers to
organize their work in the field, the feature is now integrated throughout FlexColor
and can therefore also be used with all studio-photography work and 3F scans.
Though you can use the system any way you like, the intention is that you should
assign the levels as follows:
