ISO, EXPOSURE... What the
FLUT
?
Exposure
can force clipping the same way opening the aperture can - it is a linear adjustment of
brightness values.
FLUT
and
ISO
gently bend the tones in the image to avoid clipping using gamma
curves. A
FLUT
of +1 is the same as doubling
ISO
(IE one stop more perceived brighness), but
FLUT
gives you finer control over the over-all image brightness and avoids clipping highlights. The
ISO
,
exposure
, and
FLUT
settings are all
metadata
and can be changed within the Redcode Raw file at any
time, including in post after the footage is shot.
Flut
is found under the
Video
menu.
ISO
is found under the
Sensor
menu.
Exposure
is not found in
the camera menu structure, but rather in the expanded metadata toolbox of RedCineX Pro, or Adobe
Premiere Pro.
Timelapse/Intervolometer
As of Firmware V4 the Scarlet has built in timelapse/intervolometer functions.
FRAME PROCESSING
You can select the following frame processing settings: NO FRAME PROCESSING, FRAME SUMMING,
FRAME AVERAGING.
NO FRAME PROCESSING
Normal frame processing mode. The FRAMES TO PROCESS selection will not affect your recording.
FRAME SUMMING
The Frame Summing setting takes the number of specified frames, combines them into 1 frame, and adds
together the exposure time for each of the original frames. Frame summing results in a final image that is
brighter and possibly blurrier than any of the original frames. You can use frame summing to achieve the
effect of long-exposure.
For example, if you select 16 as your FRAMES TO PROCESS value, and set your exposure to 1/48 sec,
your resulting image will have a new exposure value of 1/3 sec (16 x 1/48).
