Hi,
When tweaking curves and histograms I typically have the real time preview window up. Very handy. Now it would be great if the cursor in readout mode would not show modified pixel values but *original* pixel value. I don't think it makes much sense to show modified pixel values in the bottom (original) histogram for example. In effect the pixel values go through a double transformation by the time they end up in the top histogram window.
I think the same should apply for modified previews.
Thanks for considering this.
