assistant: ### Cineon & DPX

Cineon is Kodak’s standard for film scanning, 10 bits per channel and logarithmic.
DPX has been derived from Cineon as the ANSI/SMPTE industry standard.
DPX supports 16-bit colors/channels, linear as well as logarithmic.
DPX is currently a widely adopted standard used in the film hardware/software industry.

DPX as well as Cineon only stores and converts the “visible” color range of values between 0.0
and 1.0 (as a result of rendering or composite).

### OpenEXR

[ILM’s OpenEXR](https://www.openexr.com/) has become a software industry standard
for HDR image files, especially because of its flexible and expandable structure.

An OpenEXR file can store multiple layers and passes.
This means OpenEXR images can be loaded into a Compositor keeping render layers and passes intact.

#### Output Options

Available options for OpenEXR render output are:

Color Depth
:   The exponent value (with base two) for how many colors can be represented within a single color channel.
    A higher bit depth will allow more possible colors, reducing banding, and increasing precision.
    Yet a higher bit depth will increase memory usage exponentially.

    Float (Half):
    :   Saves images in a custom 16 bits per channel in a floating-point format.
        This reduces the actual “bit depth” to 10-bit, with a 5-bit power value and 1-bit sign.

    Float (Full):
    :   Saves images using 32 bits per channel in a floating-point format.

Codec
:   The type of compression to encode the EXR-file with.

    None:
    :   Disables all compression for fastest encoding times but creates larger file sizes.

    ZIP:
    :   Lossless compression using Zlib on 16 row image blocks.

    PIZ:
    :   Lossless wavelet compression, effective for noisy/grainy images.

    DWAA (lossy):
    :   JPEG-like lossy compression on 32 row image blocks.

    DWAB (lossy):
    :   JPEG-like lossy compression on 256 row image blocks.

    ZIPS:
    :   Lossless compression using Zlib, each image row compressed separately

    RLE:
    :   Lossless run length encoding compression, works well when image rows have the same values.

    Pxr24 (lossy):
    :   Converts 32-bit floats to 24 bits then uses deflate compression.
        Pxr24 is lossless for half and 32-bit integer data and slightly lossy for 32-bit float data.

    B44 (lossy):
    :   Lossy compression for 16 bit float images, at fixed 2.3:1 ratio.
        B44 compresses uniformly regardless of image content.

    B44A (lossy):
    :   Lossy compression for 16 bit float images, at fixed 2.3:1 ratio
        with further compression on areas of flat color are further compressed, such as alpha channels.

Quality DWAA (lossy) DWAB (lossy)
:   Controls the level of lossy compression applied to the image, expressed as a percentage.
    Lossy compression reduces file size by discarding some image data, which may result in a loss of detail.

    - **0%**: Maximum compression, producing the smallest file size but the most noticeable quality loss.
    - **100%**: No compression, preserving full image quality at the cost of a larger file size.

Interleave
:   Use legacy interleaved storage of views, layers and passes for compatibility with
    applications that do not support more efficient multi-part OpenEXR files.

Preview
:   When rendering animations (or single frames via command line),
    save a JPEG copy of the image, for a quick preview.

### Radiance HDR

Radiance is a suite of tools for lighting simulation.
Since Radiance had the first (and for a long time the only) HDR image format,
this format is supported by many other software packages.

Radiance `.hdr` files store colors still in 8 bits per component,
but with an additional (shared) 8-bit exponent value, making it 32 bits per pixel.
