Hello All Sellers, It’s Quick question. With Photoshop in 16-bit mode, is a JPEG image actually being processed above 8-bit depth or simply within 16-bit depth?
It will be, If you do anything to the image that multiplies the (original 8 bit) pixel values by something that results in a ‘fractional’ answer, using 16 bit will allow that accuracy to be held and further multiplied, before the output translation/rounding to 8 bit again for us to view.
If you start 8 bit and process 8 bit, each successive process step MAY result in successive rounding errors and the final result may look obviously posterior - or you could call it “painterly” and insist it was deliberate.
Lets discourse about this topic…
