Works by assuming a prior model for images
that models them as mainly smooth areas and edges
they inherently remove "texture"
that is, fine detail which is not edges
most people don't seem to notice this or be bothered by it
me, I notice, and it bothers me a lot
it makes everything look a bit cartoony
too much edge and smooth
Of course I find myself rather alone in generally hating the overly-computer-processed look that everyone favors these days. I despise false color HDR manipulations. I vomit at all the super pumped-up contrast photos used for real estate ads. I can't stand all the weird filters used on movies these days.
