Photoshop CS6 A little-known palette feature

So far, I have not found a few people use this function, so, today to introduce.

First of all, you have to use the extended version of the CS6, this feature lurks very very very ... Deep. Well, well, not suspense, in fact, this is an adjustment layer, so that is not a latent deep. This adjustment layer is called "Color lookup"!

Color Lookup adjustment layer can achieve advanced color changes, such as Edgyamber or bleachbypass or something.

The other reason I estimate the number of people with less is that this part is not translated in the Chinese version. So, today, I am good people to do the bottom, this part of the light effects are translated again, and are streamlined to two words within, haha, this is actually my most proud part (except the first two).

Although color lookup is not the best fine color adjustment tool, it can create multiple color versions in just a few seconds, and it's great to find a big feeling. Of course, itself is the adjustment layer, if the mask can also be more precise color palette, wow, click, try it quickly.

One for the original, and then you can try a variety of tonal effects.

Why this color lookup function looks very cooooool~, because it is the movie level color palette concept. For everyone to add

Background knowledge:

Lut

The Digital intermediate (Digital Intermediate, DI) technology came up about ten years ago and encountered a difficult question of how to make interactive color matching for different devices. This time we found the LUT mapping table. Now, Lut almost everywhere, But there are still a lot of people who don't understand it. In fact, we usually use the GIF format indexed color in the concept of a color table.

Lut means lookup table.

Can be used in the digital middle of the color of the display of the monitor to correct the colors, and simulate the final film printing effect to achieve the purpose of color, you can also in the process of rendering it directly as a filter to use.

So what is 3D LUT

* One-dimensional LUT (1D LUT) affects all channels, technically it only affects gamma.

* Two-dimensional LUT (2D LUT) are not interdependent between channels and they are handled independently. This means that you can't really deal with or forbid those colors that are not possible.

* Three-dimensional LUT (3D LUT) in each coordinate direction has an RGB channel. This allows you to map and process all the color information, whether it is a color that exists or does not exist, or a gamut that is not even visible to the film.

The future of Lut

Once the film disappears, the digital era of the film will come and we will save a lot of trouble. Today, many companies are already considering whether their films are made using all-digital processes.

The standard for display technology is difficult to unify, and many different companies have different color management standards. For example, a video playing on a projector and playing on a LCD display or playing on a CRT display will show a different color, which is a bad thing.

Therefore, we can not be separated from Lut. More importantly, LUT has become the standard and basic way of color management in many industries.
