Adjust color video app3/21/2024 Viewing LUTs are used on production sets so the crew can accurately view live shots on the monitors. Common log profiles include Sony’s sLog, Canon’s cLog, Red’s REDLogFilm, ARRI’s Log C, and Blackmagic’s Log. However, the footage appears extra flat out of the camera. Log color profiles capture footage in high dynamic range, so it lends to a more flexible color correction process. Speed LUTĪlso referred to as log normalization LUTS, speed LUTs quickly convert footage from a cinema camera’s log color profiles to more standard color spaces such as Rec. ![]() For example, if the intended viewing space is sRGB, the colorist wants their grading suite to be calibrated to that color space. That way, when colorists correct, grade, and then deliver the finished product, it is accurate and consistent with the intended viewing space. As the name suggests, they are used to calibrate or profile monitors for the correct colorspace. Calibration LUTĬalibration LUTs fall under the umbrella of technical LUTs, but are sometimes referenced separately. You may also hear this referred to as a transformation LUT. 709 footage – the standard color space for high-definition video – to DCI XYZ, which is the colorspace used for digital cinema projection. Colorists or finishers may use a technical LUT to convert Rec. Sometimes, the terminology for the different types of LUTs can change, but here is a basic breakdown of the different LUTs and their uses: Technical LUTĪ commonly used LUT in post-production, the technical LUT transfers footage from one color space to another. There’s a variety of LUTs that all achieve a different goal. More practically, LUTs act as filters that can be dropped onto images to get a desired outcome. Technically, a LUT is nothing more than a large set of numbers that remap an image’s values to change the look of the image. Everyone from the director of photography to the video editor and the colorist rely on LUTs. A LUT can be used in a variety of ways including adding an aesthetic look to an image, converting footage from one color space to another, or even to calibrate monitors on set. Some of you will go with the default monitor calibration software built into the OS.Look-up Tables, or LUTs, are a tool to use during the pre-production, production, and post-production process, although it is most commonly associated with post production. Graphics professionals will pick up serious color accuracy test tools for the job, like the Datacolor Spyder5Elite S5EL100 Monitor Calibration System. Color calibrating your monitor is important to get as close to the real thing as possible. Today, it's a lot about watching online movies, snapping digital photos, and sharing image files. Only to find out that the blue of the sky or the green of the grass doesn't resemble the one you saw through the viewfinder. ![]() Just imagine that you took a beautiful panoramic snap and downloaded it to your computer. The colors on the screen may not be the exact match of what they actually are. But its impact will be lost if you don't take the pain to carefully (and intermittently) calibrate your monitor. ![]() Why Is Display Calibration So Important?Ī good monitor is expensive. If you are either of those, you know all about monitor calibration. Pixel perfect monitor calibration is a cardinal rule for photographers and graphic artists.
