I printed a digital negative twice where I changed nothing between the two other than one was FS coated. I by far preferred the FS version and did not see a reason to recalibrate. Deeper blacks with more pop and presence to the print. Perhaps the dig neg could be tweaked to look the same I just don't have enough experience with the process yet. But I also did notice as previously noted that I seem to have more solution to coat than usual. Still early days for me but I am interested no doubt.
