  4. How can I change the strength/opacity of the 3D LUTs in Adobe Photoshop?

3D LUTs in Photoshop are applied in adjustment layers. Therefore, changing their properties is just like changing any layer’s properties.

In order to reduce the strength of a 3D LUT, you should reduce the opacity of the Color Lookup adjustment layer.

1. Make sure your Layers panel is visible
Make sure your Layers panel is visible by going to Window > Layers. If there’s a check mark next to Layers, go to step 2. If not, click on Layers to make the Layers panel visible.

Window Layer

2. Highlight the Color Lookup adjustment layer
In the Layers panel, highlight the Color Lookup adjustment layer.

3. Reduce the Color Lookup adjustment layer opacity
Under Opacity, reduce the opacity of the Color Lookup adjustment layer until desired.

Reduce Opacity

There are several ways to increase the strength of a 3D LUT. We’ll cover the following two:

1. Duplicating the Color Lookup adjustment layer
2. Changing the Color Lookup adjustment layer blending mode

Duplicating the Color Lookup adjustment layer

1. Make sure your Layers panel is visible
Make sure your Layers panel is visible by going to Window > Layers. If there’s a check mark next to Layers, go to step 2. If not, click on Layers to make the Layers panel visible.

Changing the Color Lookup adjustment layer blending mode
