When I got my 4k screen I was pleased that my lenses were sharper than I had thought. I was reasonably happy with my resizing routine, until I resized this image, with a horrible result. After some trials I tried a new routine.
After RAW development with its nominal preset NR and sharpening, I saved as .tiff lossless. I used Ps CC 2017 for some levels and brightness adjustments, then more NR, and a slight sharpen with Topaz Detail micro contrast enhancement 1. The crop was then made and saved as .jpg. The full image was then resized using Ps, resample and the bi cubic sharper options. Then saved as .jpg (10), and a small final sharpen with Usm set at 0.4mm and strength 50. The result is still disapointing.
How can I retain more of the detail available before resizing?
