Many of today’s HD sensors are
designed to work best in a daylight
balanced lighting spectrum. With
presets that compensate for tungsten
light, this often raises significant
noise in color channels under
difficult low light conditions.
Schneider’s CTB filter line balances
color temperature from tungsten
toward daylight in incremental
steps. Users then have control to
correct as much or as little of the
exposure as desired. So they can
color correct while maintaining low
noise levels at minimal light level.
The new CTB filter line has
been designed to correspond to
existing lighting color correction
standards, offering a range of
correction for most situations. Stop
loss is 0.17 for the eighth, 0.24 for
the quarter and 0.34 for the half.
These filters maintain a high
MTF (modulation transfer function).
