Let's look:
I'll start with this image from Aeon Flux. An excellent night scene with some bright areas
(which severely limit what the Panasonic's dynamic iris can do to lower black levels), the
blacks come out fairly black, easy enough to watch. The shadow detail, though is really very
good, with really no dark areas where all the detail is lost.
Below is a closeup of the building above. Look in the dark areas to the left of the bushes, and
the lowest part of the roof, the far right, and also the darkest area between the wall and the
ground in front. You'll find some details in all these very dark areas. Now, for comparison,
below that image, is a similar one from the lower cost BenQ W500, which, is definitely not a
good performer when it comes to shadow detail. The amount of difference between these two
projectors, is nothing short of stunning.
