You can use adjustment layers to quickly create / export LUT (color lookup table) files but all kinds of layers and modifications can be used before you use the export functionality. The key thing is that you have a layer

You can add two or three of the same adjustment layers (and why not) and you can also mix in opacity via the layers panel and also different blending modes (such as hard mix or hard light or difference) as well as other modifications to the layer (it is a layer in exactly the same way as a normal layer and can have all kinds of extra twists such as gradient overlays and satin to change the adjustment).

You can also use layer effects and layers to create a table to be exported. Create a new layer and then fill with white and use the layer menu and layer style commands to add a gradient overlay, set to a linear gradient say and then file and export via the color lookup table command. You can then apply it again via the adjustments command 'color lookup'

 

You also do the same with the layer styles and 'pattern overlays' as well as fill pattern layers etc Create a pattern fill layer via the layer menu and new fill content and set a pattern and scaling and then export that via the menu command. You can, of course, create multiple pattern layers and then combine them all and use the layer menu and merge the result and export as a table

 

Another interesting way to create a color lookup table is to add the color direct to the layer via multiple applications of gradients and the actual resulting table depends on the underlying image and mapping. Using a combinations of gradients to a layer (and that is the key thing) though the actual result can definitely depend on the underlying image and how everything maps out. You can use any number of gradients and combine them in 1000s of ways using blending modes in Photoshop and as long as you apply them to a layer and that can be exported via the menu command, that can be re-imported via the image and adjustments command

 

You can also just use an image for a source for a color lookup table. The image can be one that you have opened or an image created perhaps using brush strokes. The key thing is that there is a layer so duplicate that as a layer (the key thing is that is a layer) and use the export command for the tables. The results can certainly be interesting.

 

To use the generated files, simply go to the image menu and adjustments and color lookup or use the adjustment layers
