I've been restoring some old B&W images recently, using AP 2.0.4 on a Mac. These photos have been scanned on a flatbed scanner and have the Scanner RGB profile embedded. After doing a lot of edits (spot removal, Curves, channel mixer, sharpening, etc), I try to Convert them to sRGB (with all layers still in tact) and end up with a significant tonal shift when doing so. The attached AP image will illustrate the issue. This image previously had a base layer, a spot removal layer and a Channel Mixer layer. Just as an experiment, I merged those three layers into the background, and I still got this tonal shift when converting to sRGB. The only thing above the background layer are Curves, Clarity and Sharpening layers. The attached image was successfully converted from the RGB scanner profile to Gray/8 using a Generic Gray Profile, which did not cause the tonal shift. Using Gamma 2.2 or D50 profiles did cause the shift. The odd thing, is that if I flatten the entire document first, converting from the scanner profile to sRGB works fine and does NOT result in a tonal shift. While that works, I do not want to flatten the images because I want to retain all of my layer work. Also, I want to end up in sRGB because I sometimes colorize these old images. Usually, a conversion remaps all the tones and colors so the image "looks" the same after conversion, but this is not the case here. Is this a bug or expected behavior? Mom - Jim 2-2-1942.afphoto

It would be helpful if there was an tonal range option of selection that allowed a user to set a lower and upper threshold - two bars. The three current choices are not sufficient for assigning say different exposures to "bands" of tonal ranges. Most helpful would being able to set points at different tone points and being able to assign specific filters or level adjustments to each band. I understand that photoshop may have something like this, I am not familiar with photo shop. Thanks -
