also be used).
(3) Set to the Camera mode, and switch power ON.
(4) Mount the camera on a tripod, and place it squarely
in front of the high-resolution chart (ie set horizontal
and vertical at 90º).
(5) Place the high-resolution chart over the gray chart at
a distance of 1200±5mm from the front face of the
camera lens.
