I’m Colin Smith from PhotoshopCAFE.com. On this 4-minute video and article, I’ll share a brand new Photoshop method I got here up with that offers you separate management over energy, coloration, and luminosity in LUTS. I name this the Cut up LUT method.
All of us love LUTs (lookup tables). They’re a fast and moveable solution to apply coloration and tonal presets throughout platforms and completely different purposes. We name these presets appears to be like. This began in video and has now change into fashionable in pictures as properly.
The issue with LUTs is the shortage of flexibility. You’ll be able to’t alter completely different parameters. You’ll be able to solely alter the opacity or energy of the LUT. Typically, the colour is ideal, however the tone is just too darkish or vibrant. Inversely, typically the tones are spot on, however the colours aren’t what we like.
That is what received my eager about a solution to separate a LUT (or cut up it) into separate tone and coloration. I’m going to point out you ways I accomplish this proper now, and it additionally works on different purposes, not simply Photoshop. That is like frequency separation, however as an alternative of splitting into coloration and texture, we’re splitting into coloration and luminosity.
The answer is definitely actually easy — so easy, most individuals wouldn’t even give it some thought. We are going to use Layer mixing modes.
With the picture in Photoshop apply a LUT utilizing a Shade Lookup Adjustment layer.
If you wish to modify it, you may solely alter the opacity. That is the place the trick is available in.
Duplicate the adjustment layer. It’s best to now have 2 adjustment layers, and the impact of the LUT is doubled on the picture, however not for lengthy.
Change the identify of the highest Layer to Tone or Luminosity. Change the Mixing mode to Luminosity.
Rename the underside adjustment layer to Shade. Change the Mix mode to Shade.
Now, for those who alter the opacity of the colour layer, you may management the colour of the LUT. If you happen to change the opacity of the tone Layer, you may alter the luminosity.
You can even use a unique LUT for tone and coloration.
I advised you it’s straightforward, but it surely’s very highly effective. Be sure you watch the quick 4-minute video above to see this in motion and seize a few further ideas.
