Photoshop Tutorial: How to Load LUTs
Go to the Adjustments panel (Window > Adjustments). Click on the Color Lookup button.
In the Properties panel (Window > Properties), click on the dropdown menu then select "Load 3D LUT".
Adjust the opacity as needed. By default, your color lookup layer will be at 100% opacity. Our LUTs are designed to be used around 75-90%. This gives you extra headroom for increasing the effect.
