![]() ![]() Regarding devices and digital files, their color space helps us understand the range of colors they can record, or reproduce. For example, in the RGB color space, each individual color is represented by a value for red, green, and blue. The term color space describes a way of organizing colors. When the camera crew reviews footage on set, they process it with a viewing LUT from a log color space to a standard color space such as Rec709 so its appearance on a viewing monitor will be closer to the post-editing footage. These low-contrast images with muted colors result from a log footage color space, such as S-Log or Log C. ![]() Viewing: Camera footage can appear flat, depending on the device. LUTs can also quickly treat footage when it is imported, to make it more viewable on a certain device, such as a control monitor. As the name implies, all a lookup table does is find all instances of one color value and transform them into a predefined color space.įilmmakers use color grading as part of the creative process, for example, to convey emotion, apply color psychology, achieve a style or atmosphere, and establish a carefully designed color palette. This process of color correction, therefore, needs to come before you can effectively color grade using a LUT. You’d also ensure that your color values stay consistent throughout your footage and don’t vary wildly between frames or scenes. You want the color red to appear where things are actually red, otherwise, everything with a red tinge will likewise undergo the LUT enhancement. To achieve a satisfying result, you’d first have to review your footage to make sure that all the colors appear as they should. A preset solution like this saves you a lot of time in post-production: instead of having to do the changes manually, the Lookup table processes the colors for you. The LUT you would apply to your project would plug in all the color values of your footage and subdue them, but enhance the values for all defined shades of red. Let’s say that whenever the specific color red appears in your film, you want it to be bright and stand out, and all the other colors should appear faded and muted in comparison. In layman’s terms, think of a LUT as a preset you can apply to alter the color palette and give your film a specific look, from emulating old footage or a certain show to a cinematic look. Lookup tables are a way to speed up the process of color-grading footage. In this guide to color grading, we’ll go into the details of color grading with LUTs and talk about how filmmakers use LUTs with examples, a workflow overview, and resources for your film projects. Color grading can stylize the color scheme to achieve the desired effect or look, or move from one color space to another. ![]() In filmmaking, it is part of post-production and a filmmaker or colorist will color grade a film with a lookup table, or LUT for short. Color grading is a process of treating footage for technical or artistic reasons. ![]()
