The first one is the IF response. The marker is at the video carrier.
The rest are of the picture I made and played on my Blueray player
that contains images of R G B fully saturated but
different brightness on the top row, and +I -I +Q -Q on
the bottom row. The transitions on the top row were not
filtered in Photoshop (before playing the test file ... not the
camera images), while the bottom row was filtered to the
NTSC specs for the +_ I and Q transitions, and
filtered at about 0.8 MHZ for the -I to +Q one.
The final image is the histograms made from my
digital camera images of the flat (appropriately blurred)
parts of the patches. Its not perfect, and I also note that
I don't know what the gamma of the camera is ... this is
not photometric.
