When editing images in 16 bit mode within photoshop, the curve dialogue still operates on 255 steps, is there any way to make it have the fully range of steps that should go along with a 16 bit image for more precise editing ?
Also, are curves and levels applied as adjustments layers in the latest version of photoshop merged (concatenated) into one calculation when the image is flattened, or are they executed sequentially ?
I work in the visual fx/animation field as a day job and applications used for digital compositing such as shake concatenate a lot of the color correction steps a user adds in a node tree into a single lookup table to minimize any loss of values due to rounding errors.
How does photoshop handle some of this ?
