How to expand control in Photoshop LUTs
Right now, I’m going to show you how to have unprecedented control over color LUTs inside Photoshop.
The Split LUT effect, by Colin Smith
Here’s an image I grabbed from Adobe Stock.
In the Layers panel, choose a new Adjustment Layer and select Color Lookup.
In the Properties panel, click where it says Load 3d lut,
You’ll see the LUTs that come with Photoshop. I have some extras. At the end, I’ll show you how to get those.
You can use any LUT, but I’m using Filmic Cube, which is a LUT that I made. (How to make your own LUT in Photoshop)
Now, here’s the problem with LUTs. If you just want to change the color or the brightness, you can’t. (I’ll show you a hack in a sec) The only adjustment I have is to change the opacity to change the strength of theLUT.
What I’m looking for is a way to control the color and the tone individually. And guess what I’ve figured out. Of course, I have. This is what I’m showing you in this tutorial. So the trick is actually quite simple. I’ve come up with a sort of frequency separation for color and tone, I call it Split LUT.
Press Ctrl/Cmd+J to duplicate the adjustment layer.
Name the top layer: tone, and then the bottom one; color. Y
Change the blending mode of the tone layer to luminosity. (Click on “normal” and choose luminosity.)
Choose the color layer, and let’s change the blend mode. Once again, click on normal, go down to color.
So what I’ve done here is essentially split that LUT into two.
The 2 layers stacked in color and luminosity mode, should look the same as the single adjustment in normal mode.
Now you can change the opacity on the color layer, to just affect the color of the LUT.
Change the Opacity of the Tone layer to only affect the tone (or luminance).
So this kind of enables us to hack in and create a separate tone and color slider. Now,
that I’ve got for you there. I also said I was going to give you some free LUTs. So if you head over to PhotoshopCAFE.com/vault,
I’ve actually got a whole bag of goodies there that you can have for free. Grab free goodies here, including Photoshop brushes, actions, presets, sky images, ebooks and a whole bunch more.
