Look at these two pictures. The one is original picture just taken by a digital camera and the other is the picture applied 'sharpness' by graphic software ' Adobe Photoshop 5.0 '. The pattern of the pot looks distinctly outlined. Yeah, some patterns are so improved in appearance as if it were another picture by the application of 'sharpness'. Oh no, it's beyond its power.
Nothing comes of nothing.
Therefore, it is originally not necessary to process with a personal computer, and on the contrary, too much processing of 'sharpness' spoils the image. That's due to too much 'sharpness' processing. Too much 'sharpness' makes an image unnatural like that and it increases noise. But Go-inkyo, none but digital would make such processing. But, interestingly enough, similar thing is made in the silver-halide film.
