Maximum Score 30/100
See current scoring methodology HERE
Focus is of course an obvious image quality parameter. There are a number of factors impacting on image focus but all we are really interested in here is the final outcome. I have kept this very simple.
(1) The image looks perfectly sharp in which case edges are crisp and well defined.
(2) The image looks soft. Detail is still there and the image is reasonably usable but the edges are not totally crisp.
(3) The image is out of focus. The whole image is very soft and details are hard to make out. It is not really a usable image for identification purposes.
