[Leica] CS4 Extended Depth of Field Trial

[leicar at q.com (Aram Langhans)]

My understanding is that it looks at each layer (photo taken with a
different focal point) and looks for the sharpest details and masks the rest
of the photo.  When it is all done, you can look at each layer and see what
is has chosen as "in focus" and see how it masks the rest out.  Not sure
what it did in the case of the leaves that were moving.  It is really
remarkable.

I put my Leica 35-70/4 on my Rebel XTi and set it up on a tripod.  I used
f-4 or 1/2 stop down (I forgot) and focused on the front of the sundial,
then gradually moved the focus point further back until about 6 exposures
later, I was focused on the back of the sundial.  I plan on trying a much
deeper trial maybe today. I'll pick a subject w/o any moving leaves or
objects this time.  I was going to try my picket fence, but thought that
would be too academic and boring.  Sundials are more interesting to me.
