### Input
-- Description: Colorspaces and transforms that implement the ACES Input Transforms. These colorspaces are used to convert from camera-specific formats and encodings to ACES.
-- Colorspaces: There are a variety of Input Transforms covering different cameras manufacturers, gamuts, transfer functions and camera settings. See below for specifics.
+##### Colorspaces
-- Technical information: References and descriptions are provided for each group of Input Transforms below.
- - The colorspaces whose names include a transfer function and a gamut name are full implementations of ACES Input Transforms.
- - Ex. The ARRI 'V3 LogC (EI160) - Wide Gamut' colorspace
- - Ex. The RED 'REDlogFilm - DRAGONcolor2' colorspace
- - Ex. The Canon 'Canon-Log - DCI-P3 Daylight' colorspace
- - The colorspaces that start with "Linear - " will convert to or from a specific gamut but not apply a transfer function.
- - The colorspaces that start with "Curve - " will apply a transfer function but not convert between gamuts.

### Utility
-- Description: A collection of colorspaces that are used to facilitate the creation of LUTs and other basic functionality.
+##### Description
-- Technical information:
- - The 'Log2 xx nits Shaper' and 'Dolby PQ xx nits Shaper' spaces cover the linear range centered around 18% grey. The 48 nits spaces cover -6.5 stops (0.0028125) to +6.5 stops(16.291740). The 1000 nits spaces cover -12 stops to +10 stops. The 2000 nits spaces cover -12 stops to +11 stops. The 4000 nits spaces cover -12 stops to +12 stops.
- - The LMT shaper spaces cover the linear range going from 10 stops below 18% grey (0.00017578125) to 6.5 stops above 18% grey (16.291740)
- - The colorspaces that start with "Linear - " will convert to or from a specific gamut but not apply a transfer function.

### Roles
-- Description: The role colorspaces are aliases to the colorspaces used for the OCIO 'roles' functionality.

+The role colorspaces are aliases to the colorspaces used for the *OCIO* 'roles' functionality.
### Aliases
-- Description: The alias colorspaces are named with all lower-case letters and no spaces, dashes, parentheses or other characters that would not work well in a filename. They are only references, aliases for the base colorspaces with more user-friendly names. These spaces were added to enable OCIO's token-based colorspace / filename matching.
- - These colorspaces should not generally be used by most artists.

Roles
-
-The standard OCIO roles are defined. They role assignments are:
-
-- color_picking: Output - Rec.709
-- color_timing: ACEScc
-- compositing_log: ACEScc
-- data: Raw
-- default: ACES2065-1
-- matte_paint: ACEScc
-- reference: Raw
-- scene_linear: ACEScg
-- texture_paint: Raw

+
+- **color_picking**: Output - Rec.709

+- **compositing_log**: ACEScc
+- **data**: Raw
+- **default**: ACES2065-1
+- **matte_paint**: ACEScc

Additionally, a number of colorspaces that are gaining wider adoption have been added to the config. Their names and assignment are:
-- compositing_linear: ACEScg
-- rendering: ACEScg
+- **compositing_linear**: ACEScg
+- **rendering**: ACEScg
Displays and Views
-
+
The default config has one Display named **ACES**, which contains the following Views / colorspaces:
- sRGB D60 sim., colorspace: sRGB (D60 sim.)
- Raw, colorspace: Raw
- Log, colorspace: ACEScc
-Considerations for custom config generation
+Considerations for custom config generation:
- The choice of a single Display and many Views may not align well with the implementation of OCIO in an application.
- If you would like to generate a config that contains multiple Displays, with a small number of Views for each, review the config generation script's '--createMultipleDisplays' option.
The default resolution is 33x33x33 for the 3D LUTs and 1024 for the 1D LUTs.
