Using LightSpace CMS for User Created Calibration LUTs 20131001 Flanders Scientific, Inc. 6215 Shiloh Crossing Suite G Alpharetta, GA 30005 Phone: +1.678.835.4934 Fax: +1.678.804.1882 E-Mail: Support@FlandersScientific.com www.FlandersScientific.com Using LightSpace CMS for User Created Calibration LUTs 1. If you will be using a colorimeter for display profiling we highly recommend the use of monitor model specific spectroradiometer determined offset files to ensure accurate readings. If you are using a spectroradiometer please skip to step 3. If you are using a colorimeter please continue to step 2 to load your offset files. Flanders Scientific can provide you with these offset files if you: A. Purchase your colorimeter from FSI. B. Send you colorimeter to FSI for offset creation. 2. Loading offset files for your colorimeter. A. First, open the calibration interface (target button). B. Next, click on the Probe Options button. C. Under the Active Probe/Display Data field click on the Import button. Select your display specific spectroradiometer Builder Probe Data (bpd) file. Then click open. D. Click on the same import button as in step C. This time select your display specific colorimeter Builder Probe Data (bpd) file. Then click open. 2 © 2013 Flanders Scientific, Inc. Using LightSpace CMS for User Created Calibration LUTs From the drop down selection under the Active Probe/Display Data field select the colorimeter bpd file you imported. Then from the Reference Probe/Display Presets dropdown selection choose the spectroradiometer bpd file you imported. 3. From the probe options dialogue box make sure to select appropriate Integration time and calibration settings for the probe you plan on using. *LightSpace Light for FSI customers we suggest using an integration time of around 0.5 seconds and an extra delay time of 0.25 seconds. 4. Next press the MENU button on the FSI monitor. Go to the Color Management/Display Alignment menu, find the LUT Bypass menu item, and change this from the default NONE to 3D LUT. Color Management 5. For optimal calibration results it helps to check, and adjust if necessary, the monitor’s white balance and luminance setting before profiling with LightSpace. If you own a Minolta CA-310 with FSI Direct Connect Alignment Kit you can use this kit to automate this process. If using another probe simply use backlight setting (for LCD monitors) to adjust peak white luminance to your desired setting and RGB Gain and Bias adjustments to get optimal white balance results. You can generate white and grey patches from LightSpace as well as take manual readings for these adjustments. 3 Red Bias Green Bias Blue Bias Color Space Video Clipping Lut Bypass Update DIT LUT Save DIT LUT DIT LUT Update Firmware Update CFE Update MHD 50 50 50 Rec 709 Off None Off © 2013 Flanders Scientific, Inc. Using LightSpace CMS for User Created Calibration LUTs 6. Go to the Display Characterization tab within LightSpace and select your desired profile cube size. Larger profiles typically produce better results, but take longer to perform. Select closed loop or DIP mode depending on how you plan to generate test patches, then center your probe to the center of the screen and press the measure button to start the profiling process. You will be asked to name your profile. Make sure to take note of this name as it will be required to create your 3D LUTs. 7. Once your profile is complete go to the Convert Colour Space window and type in the name of the monitor you are profiling. This name MUST match the model name of the unit you are loading a LUT to. A mismatch here will prevent the LUT from successfully loading to the monitor (ERROR CODE 3). Valid model names are LM-2461W, CM-170W, CM171, CM172, CM240, CM250, CM320TD, CM500TD, BM210, BM230. 8. In the source dialog select the colour space you wish to create a LUT for (e.g. Rec709, EBU, etc.) In the destination colour space dialog select the monitor profile name you selected in step 6. 9. Now press the Create New button to generate your 3D LUT. 10. Once your LUT has been created select File > Export. 4 © 2013 Flanders Scientific, Inc. Using LightSpace CMS for User Created Calibration LUTs Select FSI64_32bit (*.dat) as your export format. Press the export button to save your 3D LUT. 11. Once your file is saved change the name of the LUT to match the position you would like to load it into. Valid LUT names are user1.dat, user2.dat, user3.dat. You can also name the file Rec709.dat, EBU.dat, or SMPTEC. dat, but please note that loading LUTs with these names to the monitor will override the factory 3D LUTs. 12. Turn the monitor off by using the POWER button on the keypad. Connect the FSI update cable that came with your monitor (USB to RJ45) to the GPI port on your monitor. If you misplaced your update cable, they are available from ShopFSI.com. 13. With the monitor plugged in, but still off, place the monitor in update mode by entering the following key combination on the monitor’s keypad: MENU, ENTER, UP, DOWN, MENU, ENTER, UP, DOWN, MENU, DOWN, POWER. 5 © 2013 Flanders Scientific, Inc. Using LightSpace CMS for User Created Calibration LUTs 14. The monitor has successfully entered update mode if the Green Tally comes on followed by the Amber Tally. 15. Connect the FSI update cable (USB to RJ45) to an available USB port on your computer. After a short time, the computer should recognize the FSI monitor as a mass storage device, viewable in Mac’s Finder or PC’s My Computer. 16. Drag and drop the created LUT files to the monitor. It will take a few moments to transfer. 17. Once the files have finished transferring, on the monitor go to: Menu \ Color Management \ Update CFE Press ENTER to begin the process, and confirm with Yes when the monitor prompts you. When the monitor reboots, change Lut Bypass to None. Optimizing 3D LUTs. If using a colorimeter or spectroradiometer with limited lowlight capabilities or accuracy it can be useful to apply a LUT manipulation filter to the 3D LUT before exporting. The Relax filter in particular (try setting anywhere form 0.02 to 0.10) can help reduce lowlight banding. To access this and other filters go to Edit Menu and look under Filters for available LUT manipulation options. 6 Color Management Red Bias Green Bias Blue Bias Color Space Video Clipping Lut Bypass Update DIT LUT Save DIT LUT DIT LUT Update Firmware Update CFE Update MHD 50 50 50 Rec 709 Off None Off © 2013 Flanders Scientific, Inc.
