LUTs are designed to work within the boundaries of REC.709, meaning
they may apply the color adjustments you are looking for, but may also
affect the luminance of the image. In which case these LUTs should only
be used for delivery of content designed to be viewed in REC.709 or SDR.
When working with 3D LUTs, you can use color correction applications, as
well as applications like Davinci Resolve, Photoshop or dedicated
applications like LUTCalc. to create your own custom Looks that can then
be imported to your Atomos device.
LUT options:

of LOOKs and even compare them to the Native Video Source. Tapping the
Compare option will apply a 50/50 vertical screen split that will show both
the Natural Source Video and the selected LOOK of the LUT.
Please note that activating the 50/50 preview will also be applied to
the Loop out and is not available when LUT is set to record.
Remember by simply tapping the center of the screen you can remove
all overlays. Tap again to reveal controls.
Monitor
Before entering into the operation of HDR monitoring it is important to
understand the background of HDR. We advise that you read the Atomos
HDR Guide to familiarise yourself with the key terms and differences
betweentheexistingRec.709standarddynamicrange(SDR)andthe
futurewaywewillviewimagesinHighDynamicRange(HDR).
Using Standards - Native / Rec.709 / HLG / PQ

HDR. This is similar to the HDR slider in previous Atomos Operating
Systems, except instead of a variable slider control, we have now buttons
thatcorrespondwithRec.709(SDR),HLGandPQ(HDR)levels.
Activating these buttons will display your video according to the levels
indicated below, allowing you to adjust your exposure accordingly and
take the guess work out of exposing correctly for HDR.
Native Video Source
This option will display the video source without any processing and
the Shinobi will behave as expected for a standard broadcast monitor.
When connected to a camera this means the image you are viewing
is the untouched camera output eg. a standard Rec.709 image or a
Log image etc. A standard Rec.709 image will look correct and a Log
imagewilllookat.
