"...the unmodified camera has on the order of 7 stops latitude, but the Andromeda image shows nearly 9.5 stops. Pretty cool!"
Adam Wilt
Below are two images, one recorded through the Andromeda output of a
DVX100A, and the other through the standard compressed DV Firewire
port on the camera. The test chart was composed of stepped Neutral-
Density (ND) filters and backlit such that the precise amount of
light coming through each bar on the chart could be measured with a
light meter. Please note that both images are the exact same
frame(i.e. the exact same instant in time), but recorded
through the two different methods. Also please note that neither
image was color-corrected.
The Andromeda image clearly shows on the order of ~2.5 extra stops on
the top end of the range. If we take the standard camera to have ~7
stops, then the Andromeda system on the DVX100A has about
9.5 stops of total dynamic range.
The DVX100A Scene Settings used for this test: All variable settings
at 0, gamma on CINE_LIKE_D, knee on AUTO.

Andromeda outputs uncompressed, full color video which is free of
compression artifacts. Below are samples of a single frame, one was
recorded via Andromeda and the other via standard DV. One can
clearly see how the compression artifacts (in this case "blockies")
and decimation not only negatively affect the subjective quality of
the image, but reduce the effective resolution. This is a good
example of the compromises made when using compressed formats.
