How does nuke process color?
Nuke’s internal color management converts between different transforms using LUTs (Look Up Tables). A LUT defines a transformation which is the difference of the pixel values between the reference colourspace (linear for Nuke) and another colourspace, in the example below from linear to sRGB.
What is multi channel EXR?
OpenEXR is a high-dynamic range, multi-channel raster file format, released as an open standard along with a set of software tools created by Industrial Light & Magic (ILM), under a free software license similar to the BSD license.
How can I OpenEXR files for free?

What is an EXR file used for?
OpenEXR, or EXR for short, is a deep raster format developed by ILM and broadly used in the computer-graphics industry, both visual effects and animation. OpenEXR’s multi-resolution and arbitrary channel format makes it appealing for compositing, as it alleviates several painful elements of the process.
What is shuffle node in nuke?
You can use Nuke’s Shuffle node to rearrange the channels from a single image (B input) or two images (B and A inputs) and then output the result to the next node in your compositing tree. Select Channels > Shuffle or press Tab in the Node Graph and type Shuffle to create a Shuffle node.
What is channel Alpha?
The alpha channel (also called alpha planes) is a color component that represents the degree of transparency (or opacity) of a color (i.e., the red, green and blue channels). It is used to determine how a pixel is rendered when blended with another.

What are the advantages of working with eXRS in Nuke?
In this tutorials, we will overview some of the main advantages of working with EXRs in nuke OpenEXR is a HDR file format created and Open-Sourced by Industrial Light & Magic, and has really been a great addition to CG workflows offering multi-channel support conveniently in a singe file.
How do I share metadata between images in Nuke?
Nuke allows the inspection and customisation of parts of this metadata, and also permits copying such metadata between images. There may be situations where you need to share metadata without providing the pixel data. This can be done in Nuke by copying the metadata from a source image, and inserting it into a sample EXR image.
Is it possible to export custom metadata from Nuke?
NOTE: As EXR is the only format currently within Nuke that allows the exporting of custom metadata, this technique is unfortunately limited to rendering as EXR files. For more information on using the ModifyMetaData and CopyMetaData nodes, please refer to the following Online Help links:
