Below are some examples of situations where you might need to alter the default LUTs.
Emulating compositor software that works in video color space is not recommended. However, if you do need to do so, do the following:
| 1. | Select Edit > Project Settings and go to the LUT tab. |
| 2. | Under Default LUT settings, change the monitor, 8-bit files, and 16-bit files values to linear. |
This prevents Nuke from converting from sRGB into linear. Nuke’s nodes still assume linear data, but the image processing is applied to your unlinearized video color space images.
Some facilities use linear data in 16-bit files. If this is the case in your facility, do the following:
| 1. | Select Edit > Project Settings and go to the LUT tab. |
| 2. | Under Default LUT settings, change the 16-bit files value to linear. |
Some facilities have adjusted their monitor electronics to correctly display Cineon data. If this is the case in your facility, do the following:
| 1. | Select Edit > Project Settings and go to the LUT tab. |
| 2. | Under Default LUT settings, change the monitor value to Cineon. |
Although true color management requires using the Truelight or other nodes, it may be useful to approximate it with a LUT that is used for the monitor setting. This way, texture maps and postage stamps resemble the final display more accurately.
If your color management is creating a monitor-corrected image, you’ll want to set monitor to sRGB so you get reasonably monitor-correct output on non-Viewer images.
