+ - ACES2065-1
- ACEScc
- ACESproxy
- ACEScg
- Description: Colorspaces and transforms representing the ACES ADX spaces used for film scanning and printing.
- Technical information: Transforms generated based on the [ACES CTL Transforms](https://github.com/ampas/aces-dev/tree/v1.0/transforms/ctl)
- - [Alex Fry's ACES 0.7.1 OCIO config](https://github.com/imageworks/OpenColorIO-Configs/tree/master/aces_0.7.1) as also a valuable resource.

### Look
- ACES 1.0 to 0.7 emulation
- Description: Colorspaces and transforms emulating the look of the ACES 0.1, 0.2 and 0.7 release.
+ - Should be applied to data in the ACES2065-1 colorspace.
- Should be used before an ACES Output Transform
- Technical information: Transforms generated based on the [ACES CTL Transforms](https://github.com/ampas/aces-dev/tree/v1.0/transforms/ctl)
- Rec.709
- Rec.709 (D60 sim.)
- Rec.2020
+ - Rec.2020 ST2048 (1000 nits)
- DCDM (P3 gamut clip)
- DCDM
- - P3-D60 PQ (1000 nits)
- - P3-D60 PQ (2000 nits)
- - P3-D60 PQ (4000 nits)

- P3-D60
- P3-DCI
- Description: A collection of colorspaces that are used to facilitate the creation of LUTs and other basic functionality.
- Technical information:
- - The Log2 shaper, Output shaper and 'Dolby PQ Scaled' spaces cover the linear range going from 6 stops below 18% grey (0.0028125) to 6.5 stops above 18% grey (16.291740)
+ - 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.
- The colorspaces that start with "Curve - " will apply a transfer function but not convert between gamuts.
+### Roles
+
+- Description: The role colorspaces are aliases to the colorspaces used for the OCIO 'roles' functionality.
### Aliases
-
The standard OCIO roles are defined. They role assignments are:
-- color_picking: ACEScg
+- color_picking: Output - Rec.709
- color_timing: ACEScc
- compositing_log: ACEScc
- data: Raw
- P3-D60 PQ 4000 nits, colorspace: P3-D60 PQ (4000 nits)
- P3-DCI, colorspace: P3-DCI
- Rec.2020, colorspace: Rec.2020
+- Rec.2020 ST2048 1000 nits, colorspace: Rec.2020 ST2048 (1000 nits)
- Rec.709, colorspace: Rec.709
- Rec.709 D60 sim., colorspace: Rec.709 (D60 sim.)
- Raw, colorspace: Raw
- The resolution of 1D and 3D LUTs
- Inclusion of custom Looks
- Two modes of creating the list of OCIO Displays and Views
+- Selection of shaper function: Log2 or Dolby PQ
### CTL Source
-The configuration depends on the **'hotfixes' fork of the 1.0 ACES CTL** that is available here:
+The configuration depends on the **1.0.1 ACES CTL**. The release contains a number of minor bug fixes and small additions in the utilities folder but is otherwise the same as the master ACES 1.0 release.
