Webb1 juni 2016 · The biggest problem is that, in large part, sharpness is subjective. Sharpness is a combination of two factors: resolution and acutance. Resolution is straightforward and not subjective. It's just the size, in pixels, of the image file. All other factors equal, the higher the resolution of the image—the more pixels it has—the sharper it can be. WebbUnfortunately due to some sharpness issues and severe..."
