Building blocks of REVEAL Color Science
REVEAL rests on four solid foundations that translate the sensor data into a LogC4 image.
REVEAL Color Science
Unveil the true beauty of your images
More accurate color reproduction
Cleaner images
Faster and easier grading for SDR and HDR
-
ARRI Debayer Algorithm ADA-7
- First step in the new and improved image processing chain
- Converts ARRIRAW into camera-native RGB image data
- Makes the most of ARRI sensors
- Sharper images and cleaner edges
- Easy compositing speeds up VFX work in post
-
ARRI Color Engine ACE4
- Transforms camera-native RGB image data into the AWG4 color space
- Brings what the camera 'sees' closer to human visual perception
- More accurate and subtle color reproduction
- Pleasing and naturalistic rendition of all skin tones
- Better color tracking and differentiation at all exposure levels
- Greatly improved bright saturated colors
- Same color tones in SDR and HDR
-
LogC4 Curve
- Encodes brightness changes
- Captures the sensor’s increased dynamic range

Below are images shot in ARRIRAW with ALEXA Mini LF.
Drag the slider to see the results of processing the images with REVEAL.
Original color science on the LEFT and REVEAL Color Science on the RIGHT.
While there is nothing wrong with the image created by the original color science (ARRI color is the gold standard of the industry), the image created by REVEAL shows some obvious improvements.
Reds are rendered more naturally in the OPEN sign, the scooter brake lights, and the Chinese lanterns. The purple reflection on the concrete to the right of the scooter is also more defined and accurate.

ALEXA 35 and ALEXA Mini LF match extraordinarily closely in REVEAL. For this comparison, a digital color picker was used to grab values off each of the color chart’s sample colors. They were then added to an Excel table so that color shifts could be seen more clearly.
In the grayscale version of this image, differences in luminance can be seen between some of the samples. This is because REVEAL is not only accurate with hue and saturation, it also correctly reproduces the perceptual brightness of colors.
LogC4 display LUTs (Look-Up Tables)
- Transform LogC4/AWG4 images into various display color spaces
- Take full advantage of ARRI sensors and LogC4/AWG4
- Should be used for all LogC4 images
- Improved color fidelity
