Which illustrates the effect of
setting the brightness higher
than the default value of 725. It
should be noted that this setting
moves the response curve to the
left; therefore increasing the 8bit
value output from the camera for
any given 10bit value from the
sensor, and also increasing the
apparent brightness of the
image.
The bottom graph illustrates the
effects of setting the brightness
lower than the default value of
725. It should be noted that this
setting moves the response
curve to the right; therefore
decreasing the 8bit value output
from the camera for any given
10bit value from the sensor and
also decreasing the apparent
brightness of the image.
