# How to use lut？

## Apply

1. The LUT function is turned off by default. Enabling the switch will use the D5's default LUTs. 
2. There are five D5 default LUTs, which can be switched in the drop-down menu to correspond to different colour representations.

## Intensity&#x20;

This parameter is used to control the degree of influence of the LUT on the original picture, the default value is 1, the LUT colour mixing effect reaches the strongest. Pull the control to the left to reduce the value, you can weaken the LUT colour mixing effect, the intensity value is 0, the original image will be displayed.&#x20;
