Most professional photographers who print their work use this everyday: Black Point Compensation. Black Point Compensation exists because of one reason. In order to make blacks darker on a printed piece of paper, the black dots of ink need to be larger than normal. But because the black dots are larger they also spread out more and overlap a bit (think pancakes sticking together on a frying pan). This ends up blocking shadow detail. Adobe came up with a nifty algorithm that opens up the shadows in the image ever-so-slightly and “compensates” for this blocking of the tones in the print while maintaining a full dark black at the deepest point in the image. Tomorrow, rendering intents. 🙂
