Midtone Slider in the Gradation Window

Modifying the Current Preview

When you have loaded a 3F file into the main FlexColor preview window, you can
modify its history from here, without needing to go back to the Thumbnails window.
To do this, make whatever settings you want while working with the preview and then
select Image > Modify from the menu bar. This opens the Modify window, which you
can then use to modify the current image as described above.
Midtone Slider in the Gradation Window
In FlexColor 4.5, the Histogram window now features a midtone slider on the RGB
graph. This slider replaces the old setting, which was in the
Gamma Gradations
window in FlexColor 4.0.

Using the Midtone Slider

The midtone slider appears in the graph of the window. When you
RGB Histogram
move the slider, you are adjusting the gamma curve for the image, which lightens or
darkens the midtones without affecting the highlight or shadow points. The effect is
similar to using the curve on the Gradation window, except that the shape of the
gamma curve is strictly defined at each value, making it practical to use together with
color management.
The default midtone value for the new setups included with FlexColor 4.5 is 1.00.
This value is selected to match the new color profiles provided for Flextight Scanners
and Ixpress Cameras. This value maps to the standard for defining the shapes of
gamma curves.
To use the midtone slider, simply click and drag it to the left to lighten the image or to
the right to darken it.
Note that when you are using a scanner (or working with scanned images), then you
can also use the window to adjust the highlight, shadow and midpoint
