LUT's - lookup tables : load, or make, and use

[denzjos]

It is easy to correct or change the colours from a set of pictures with LUT's.

Can one make LUT's? Yes, with G'Mic-Qt. 
- load a picture and make a layer copy
- make a new layer and correct or change the colors in the layer copy
- use G'Mic-Qt / Colors / CLUT from After - Before Layers
- set the 'Output Mode': Save CLUT as cube or pngFile (use cube)
- fill in 'Output Folder' (make a folder where you put all your 'cube' files) 
- fill in 'Output Name'  (a name that clarified what the LUT does - better for later use)
- click on the 'OK' button
The LUT can now be used for other pictures.
- load a picture
- G'Mic-Qt / Colors / Apply External CLUT
- choose the 'HaldCLUT Filename (folder where you saved the cube file)
- done
Example (I used a LUT I made before from another corrected photo)
