![]() Technical are specific to a manufacturers own equipment and will look bad applied to any other. It should be noted though there are two types of LUT, technical and creative, the former being more applied to what is said above about standardised software, cameras, or monitors to change that pixel's value to 76,218,216 (teal). The popular post-processing tool ReShade, which many Game Guru developers (including myself) employ, supports LUTs. I first noticed this a couple of years back with Cities: Skyline, where mods began to appear that applied LUTs to the game to reduce the saturated, cartoony default visuals of the game and turn them into something more natural. LUTs have recently begun seeping into the world of gaming as a method of post-processing. The advantage of a LUT file is that it compressed lots of complicated post-processing effects like contrast, brightness, saturation, hue shift, selective colour grading, luminance, gamma, curves into one file. and transform the output into stylised, colour graded imagery such as this. Combined, these tools allow you to shoot an extremely flat image that doesn't over or underexpose the image. LUTs have been commonplace in the film industry for about 15 years but have, in the last 5 or so, exploded into the prosumer videography market thanks to the advent of free powerful colour correction software like DaVinci Resolve, and the development of prosumer video cameras and DSLRs that shoot flat, Log colour space video. For example, if the source image has a pixel that has the RGB value 76,150,218 (pale blueish), the LUT can tell your software, camera, or monitor to change that pixel's value to 76,218,216 (teal). Essentially, a LUT is a table of values that can be read to change one pixel's value to another. It comes from my homeland, the film industry, and was developed as a method for standardising the grading and colour correction of multiple shots in a scene, sequence, or entire film. Quote: "What are they and what do they do?"Ī LUT or Look- Up Table is a method of image post processing that applies precise mathematics to achieve changes to brightness, colour saturation, hue, and contrast. Will need to take a look into that in GG. Here's a couple examples of it working, I can blend two LUT's using it in 'another' engine. It isn't a magic button and creating a good table for a scene takes work but when it works its pretty awesome. It can be a bit hit and miss even for specifically made LUT's and one can make a scene look awsome and the same one look bad in a different scene so you dont want it to be applied across levels etc, exposure plays a huge part in how it will affect. Thanks for the info, in the past I have been faking LUT colour correction in fpsc and GG with a really hack method where I would take a screenshot of a level and bring it into Photoshop, changing contrast,brightness,saturation etc and then saving actions to batch apply to entity textures in scene it's a crazy method which works up to a point and wont affect atmospherics obviously.Įasy way to create your own LUT's is to paste a default LUT image into a captured screenshot and make all the necessary image changes to get the look you want then crop the LUT out of it and apply as full screen effect.
