The last few version of Photoshop (from PS 6, I think) have a powerful tool called LUT (or Look Up Tables). You can think of LUT as a way to apply a color scheme to a photo. Kinda like color grading or coloring. In fact, LUTs are often used in the video industry to create a certain look.
Applying an LUT is easy, there is an adjustment layer for that, but how do you create an LUT? Jesús Ramirez (of Photoshop training channel – PCT) shares how to apply and tweak LUTs, but more importantly he shares how to create those luty creatures.
You apply an LUT by adding an adjustment layer of the LUT type. You create an LUT table by exporting a group of adjustment layers. This is all explained in the movie below
The nice thing, once you create a lookup table, you are not restricted to using it in photoshop. You can use it in premiere, after effects speedgrade and practically anything that is made to work with Look Up Tables, including hardware devices.
One quick note for PC users, the number of LUT presets available with the Windows version of photoshop is smaller than the number of LUT presets available with MAC.
