CalMAN 3D LUT Files

for Image Editing Software

Quick Start Guide

CalMAN Display Calibration Software can now create a display calibration 3D LUT file that can be

imported into many video and image editing software systems. CalMAN creates an optimized 3D

LUT file that applies calibration correction to the display to correct its performance to very

accurately comply with a desired video standard (e.g. BT.709, sRGB, etc.). CalMAN currently creates

the following common LUT file formats: .3dl, .csv, .cube, .m3d, .clt, .itx, .txt, .dat, and .mga formats;

plus specific file formats for many common LUT hardware devices.

When a display calibration LUT is imported into an editing software program, the program’s output

signal is then altered, according to the LUT data, to produce an image on the display that complies

with the selected video standard. Programs that are compatible with the LUT file formats that

CalMAN currently produces include:

 Adobe; After Effects

 Apple; Color

 Assimilate; Scratch

 Autodesk; Lustre, Flame/Inferno, Flint, Smoke, Fire

 Blackmagic Design; DaVinci Resolve

 Chaos Group; Pdplayer

 The Foundry; Nuke

 And, others for which detail is not yet provided

Required CalMAN Software Version:

 Version 5.1.0.1130 or later

Required CalMAN Workflow:

 Color Cube (3D LUT) workflow

CalMAN Software 3D LUT Setup Follow this procedure to produce a display calibration 3D LUT file with CalMAN and load that file into a number of video and image editing software programs. Open CalMAN Color Cube Workflow The Color Cube workflow in CalMAN version 5.1 or later is used to create display calibration 3D cube LUTs. In the CalMAN main menu, select Open Workflow Template / Color Cube (3D LUT). 1.

2. Display Pre-Test In the Display Pre-Test section of the Color Cube workflow, on the Test/Document Display and Check Linearity pages, you can measure the performance of a display before you calibrate it. On the Display Performance Test page, the previous display measurements are evaluated in a series of pass/fail performance parameters.

2. Select your File Format and Output Cube Size according to the requirements of the video or image editing system you are targeting. Information for a number of editing systems follows below. 3. Under File Path, select the desired directory path and provide a name for the LUT file that CalMAN will create (e.g. monitor ID and date). 4. Under Calibration Type, select the desired type of 3D LUT calibration process.

. Under Video Range, select “SMPTE (16-235)” if you are calibrating a video display that clips or compresses signals above reference white, as tested on the CalMAN Dynamic Range page. 6. Click OK. 5. Display Validation In the Display Validation section of the Color Cube workflow, you can test the performance of the display to verify the accuracy of the 3D calibration LUT. You can switch back to the Display Pre-Test section to compare to the pre-calibration performance.

1. In the CalMAN AutoCal Setup dialog, select the File Format to be 3DL, select the Output Cube Size to be 17 Points, and name your LUT in the File Path dialog. 2. Click OK in the AutoCal Setup dialog and wait for the CalMAN AutoCube calibration process to complete. 3. In Autodesk Lustre, with an image file loaded, open the Input LUT menu. In the LUT List, click the Browse button to open the Import file browser. Navigate to the appropriate source folder and select one or more LUT files. Click Import.

The Foundry Nuke: 1. In the CalMAN AutoCal Setup dialog, select the File Format to be 3DL, select the Output Cube Size to be 32 Points, and name your LUT in the File Path dialog. 2. When the CalMAN AutoCube calibration process is complete, copy the .3dl LUT file to a folder on your editing computer. 3. In Nuke, to select the LUT to use when reading or writing an image, double-click to open the Read or Write node’s properties panel. 4. From the Colorspace dropdown menu, select the .3dl LUT file you created.
