SynthEyes reads files “as is” by design: for one important example, Cineon files are not automatically gamma-corrected for display. That permits files to be “passed through” with the highest accuracy, and also allows you to select the proper image and display calibration if you like.
The level adjustments are the “simple way,” they map the specified Low level to blackest black out (luma=0), and specified High level to whitest white (luma=1), so that you can select a portion of the dynamic range to examine. The Mid level is mapped to 50% gray (luma=0.5) by performing a gamma-type adjustment; the gamma value is displayed and can be modified. You should be a bit careful that in the interests of making the image look good on your monitor, you don’t compress the dynamic range into the upper end of brightness, which reduces that actual contrast available for tracking.
The level adjustments can be animated to adjust over the course of the shot, see the section on animated shot setup below.
The hue adjustment can be used to tweak the color before the channel selection; by making yellows red, you can have a virtual yellow channel, for example.
The exposure control here does affect the processed images, if you write them back to disk. That is different than the F-P Range Control setting on the Shot Setup panel. See the section on using floating-point images.
Note that you can change the image adjustments in this section without having to re-track or adjust the trackers, since the overall image geometry does not change.
