Part of our Basic Calibration service, ICC Profiles are used to apply calibration data at the computer’s operating system level, ensuring consistency across all applications.
During Windows & Mac calibration, it is important to load a NULL ICC Profile to remove any color adjustments the computer may have added to the display.
We have also included a Sample ICC Profile (using a generic color transform) to visually verify that the ICC Profiles are loading correctly.
Our Basic Calibration service supports Mac OS X 10.6.8 or later. The following tutorial shows how to load a display calibration ICC Profile using the Mac. View the Windows version.
Note: Some third-party apps (like screen dimming) will need to be disabled before loading a new ICC Profile (or else the computer will need to be restarted afterwards for the changes to take effect).
Our Basic Calibration service supports Windows 7 or later. The following tutorial shows how to load a display calibration ICC Profile using Windows. View the Mac version.
To enable ICC Profiles for multiple displays, right-click on the desktop and choose “Display settings”. Scroll down to “Multiple displays” and set it to “Extend these displays”.
This package transforms RED material to closely emulate an ARRI Alexa’s gamma and colorspace – providing an alternative starting point for further grading.
The LUTs are based on an average of actual camera data. Additional grading may still be required to completely match the two cameras in a particular scene. Try out the Interactive Demo.
*Works with all RED camera models & sensors.
Quality
Built with precision and quality control, the LUTs have been thoroughly stress tested and do not introduce any unwanted banding or color artifacts.
Gamma
The Log3G10 gamma curve is mathematically transformed to ARRI’s LogC format. Some highlight rolloff was added to avoid clipping luminance data. This serves as the base for all other colorspace conversions.
Colorspace
The color information is transformed from REDWideGamutRGB to a variety of ARRI formats using our Camera Profiling process. Since REDWideGamutRGB is a standardized colorspace, this LUT package works across all RED camera models.
All the LUTs implement a tone-mapping process to retain out-of-gamut colors.
ARRI WideGamut
This is the foundation for all other colorspace transforms. The wide gamut colorspace provides the most room for color grading and image manipulation. This is usually combined with ARRI’s standard LogC2Rec709 transform.
ARRI FilmMatrix
An option using ARRI’s Film Matrix is included as well. This was originally built for the Alexa to mimic the color characteristics of film from an ARRI scanner. Ideal for a traditional film workflow involving a separate Print Film Emulation LUT.
AlexaV3Rec709
Intended for dailies and in-camera previewing, the LUT is based on combining our “ARRIWideGamut” LUT with the ARRI LUT Generator’s standard LogC to Rec709 transform curve, but has been re-built to better roll-off the saturation on RED footage.
ALEXA LOOK
This transform is for use as a “Creative 3D LUT” in conjunction with RED’s new IPP2 system. When used with our recommended settings, the result is designed to look similar to our “AlexaV3Rec709” LUT.
IPP2 settings: Medium Contrast / Soft Rolloff.
Post Workflow
Based on a traditional log workflow, grading should be applied after the TRUECOLOR LUT, but before the output Display LUT.
Also watch some of the recommended workflows using RED Cine-X and DaVinci Resolve:
Examples
The following video shows how our LUT compares to an actual ARRI Alexa under various lighting conditions. RED’s default IPP2 settings are also shown for reference (Medium Contrast & Medium Rolloff).
Our goal was to match each shot as closely as possible by only adjusting the White Balance, Tint, and Exposure settings. Better results could be obtained through the use of secondary color corrections.
More details about the camera settings are available in the PDF.
