BT.1886: The standardized gamma curve for standard-dynamic-range HD and UHD
display. Does not provide an abundance of latitude for grading.
Log3G12: An expanded option for RED’s IPP2 (image processing pipeline 2)
initiative, this is a wide dynamic range log space designed to encode camera data
from all RED models to a common starting point in RWG color space for convenient
grading to HDR or SDR workflows. Log3G12 provides 12 stops of dynamic range
above mid gray, 2 more stops than Log3G10. However, this is at the expense of a
slight loss of precision.
Log3G10: Part of RED’s IPP2 (image processing pipeline 2) initiative, this is a wide
dynamic range log space designed to encode camera data from all RED models to
a common starting point in RWG color space for convenient grading to HDR or SDR
workflows. 3G represents the mapping of 18% mid gray to 1/3, and 10 represents the
10 stops of dynamic range above mid gray this supports.
PDlog 685: A logarithmic gamma setting that maps the native 12-bit RED image data
into the linear portion of a Cineon or film transfer curve.
PDlog 985: A logarithmic gamma setting with different mappings.
Custom PDlog: A logarithmic gamma setting that exposes user adjustable Black
Point, White Point, and Gamma PDlog parameters so you can customize your own
log gamma curve.
REDspace: Similar to Rec. 709, but slightly altered to be more appealing, primarily
through higher contrast and lighter midtones. The predecessor to the REDgamma
curve.
REDlog: A logarithmic gamma setting that maps the original 12-bit R3D image data
to a 10-bit curve. The blacks and midtones occupying the lowest 8 bits of the video
signal maintain the same precision as in the original 12-bit data, while the highlights
that occupy the highest 4 bits are compressed. While reducing the precision of
highlight detail, the tradeoff is that there’s an abundance of precision throughout the
rest of the signal. This is a good setting for maintaining maximum latitude.
REDgamma: An improved gamma curve designed to be perceptually appealing on
displays calibrated for Rec. 709, with an improved soft roll-off in the highlights to
maintain highlight detail while grading.
REDgamma2: Similar to REDgamma, with higher contrast.
REDgamma3: The most recent iteration of the REDgamma curve. Based on a log
starting point, but with a pleasing “ready to view” contrast curve applied, designed
to be a visually pleasing starting point that maintains excellent dynamic range.
REDgamma3 is also designed to work with REDcolor3.
Blend Type: Works to control how RED HDRX media is used. When using either Simple
or Magic Motion to blend HDRX exposures, there’s no need to use the second output
in the Node Editor. You can choose from three options:
None: Only the regular exposure is used.
Simple: Blends the two HDRX exposures to achieve a pleasing middle ground.
Magic Motion: Uses a proprietary algorithm to combine the dual exposures to
combine overexposed and well-exposed regions of the picture in a more targeted
fashion, while blending the sharpness of the regularly exposed source with the
motion blur of the underexposed source.
