Channel balance
All KODAK PIKE sensors and the SONY sensor (of Pike F-505) are read out via
two channels: the first channel for the left half of the image and the second
channel for the right half of the image (divided by a central vertical line).
All KODAK equipped cameras come with a sensor-specific pre-adjusted chan-
nel balance.
However in some cases it may be advantageous to carry out a fine adjustment
with the so-called channel balance.
To carry out a
gain adjustment
