One of the things that makes a video image look crisper and sharper than a
film image is the artificial enhancement that all television cameras add to
all edges in the image. This is true of consumer camcorders and
professional video cameras alike. On most professional cameras this edge
(or detail) enhancement can be continuously adjusted or selected from
several preset levels.
With continuously variable detail enhancement, one can go from no
enhancement to almost 100% white peaks on every edge. On other high end
cameras, the detail enhancement can also be varied according to color (less
enhancement of edges in "flesh tone" reds so wrinkles on actor's faces are
less noticeable.)
The first thing one does to a video camera when attempting to reproduce a
film look is to crank out all of the detail enhancement. This really makes
the video image look soft, slightly out of focus, and "film-like," at least
to me.
