Poorly worded on my part. In that sentence I was describing how the auto level feature currently works.
I will try again.
I would like to set a few presets in the exposure, namely the highlight compression threshold, these presets are then used by the autolevels algorithm as defaults. i.e. those default will not change when the autolevels button is clicked AND the values will be considered in the calculation.
Is this possible without hacking the code?
