The whole question of contrast...

I tend to agree with a minor substitution: Photography (or perhaps we should say vision) is all about contrast, different types of contrast: an image without contrast contains virtually no information.  Conversely all of the information perceived from an image is contained in different types of contrast.

We have amplitude contrast (the range of dark and bright /luminance pixels), we have spatial contrast (local, global) , we have color contrast, we have pattern and shape contrast , etc.  These contrasts or lack thereof are what imo makes an image interesting .  Sharpness is but one of them, of the micro-spatial sort.
