A film image may pass through a camera, editing software, visual effects applications, review systems, a grading suite and several types of screen. Each device and application can represent colour differently. Without a shared system, the same shot may look correct in one place and wrong in another.
ACES, the Academy Color Encoding System, is a framework for managing that journey. The Academy of Motion Picture Arts and Sciences developed it with the film industry. ACES 2.0, released in 2025, updates how the system turns scene information into an image for different displays.
Why the camera image needs interpretation
A professional cinema camera often records more brightness and colour information than an ordinary monitor can show. The recorded image may look flat or washed out until the data has been interpreted for that screen.
An input transform tells the colour system how to interpret data from a particular camera or source. The image can then be converted into the agreed working space used by the production.
One shot, several departments
Consider a shot in which a computer generated robot walks through a filmed street. The compositor receives the photographed street and the rendered robot. Both elements must respond consistently when viewed and graded.
If the plate is interpreted incorrectly, the compositor may change the robot to match a false version of the street. When the error is corrected later, the match falls apart. A managed pipeline ensures that departments begin from the same understanding of the image data.
The working image and the viewed image are different
Artists usually work with scene referred data: values that describe light in the imagined or photographed scene. A monitor presents a limited range, so a view transform maps the scene data into an image that the display can show.
The attractive picture on the monitor is therefore a view of the underlying data. An artist needs to know whether a correction changes the scene values or only changes how those values are displayed.
What ACES 2.0 changes
ACES 2.0 introduces updated colour rendering and improved consistency between displays with different capabilities, including standard- and high dynamic range screens. It also improves the handling of intense colours and bright highlights.
A new ACES version warrants a planned migration. Changing the view transform can alter shots that have already been approved, so a studio needs to test the complete pipeline and choose one configuration before serious shot work begins.
Five questions every VFX artist should ask
- What colour space is the source file in?
- Which input transform is being used?
- What working space does the production require?
- Which view transform am I looking through?
- Is this change affecting the image data or only its display?
Production documentation, metadata and a known visual reference provide more reliable evidence than a filename. A file labelled “log” may already have been converted.
Test before the first real shot
A useful pipeline test includes skin, saturated clothing, bright lights, dark areas, a neutral colour chart and a computer generated object. Move that test through camera ingest, editing, VFX, review and final grading. If the project will be delivered for different displays, test each delivery type.
The useful goal is a clearly identified authoritative version and predictable changes across displays. Exact visual identity across every screen remains technically impossible.
Why this matters creatively
Colour management sounds technical because its work is mostly invisible. When it functions, a compositor can concentrate on whether the robot belongs in the street rather than compensating for a hidden conversion error. The colourist receives the intended image instead of repairing a chain of misunderstandings.
The filmmakers decide how the film should look. ACES helps them see and exchange that image consistently.

The Wider Shot
Colour management sits in the background of production, yet it shapes whether creative decisions survive the journey from set to screen. A shared system gives cinematographers, VFX artists and colourists a dependable basis for judgement.
This is why technical infrastructure belongs in creative conversations. Standards such as ACES carry assumptions about displays, workflows and future reuse, and those assumptions affect the image an audience receives. We believe productions make better work when artists understand the systems beneath their tools and technicians remain close to the intentions of the filmmakers. Consistency then becomes a way of protecting authorship across time and departments.
