The Nik stuff built into PL3 has two sharpening plugins, one Raw Pre-Sharpening and the other Output Sharpening. Beyond what I assume to be the obvious (Raw Pre-Sharpening is for sharpening raw images before further processing and Output Sharpening is for sharpening image before export) what is the difference between them?
That is, what does pre-sharpening do that is different from what post-sharpening does? What is the difference between sharpening raw images vs tiff? What is the difference between the Nik modules and the USM sharpening already in PL3? Or the Lens Sharpness module? Or the sharpening in the local adjustments?
