Thankfully, I’ve found a few pages that have free LUT downloads that don’t require the email signup:īuilding off of previous Python workshops, this class aims to demystify a few of the elements often used when doing advanced Python development work in TouchDesigner. Many of them require you to trade your email address for the free download but they can be worth it. You can do a web search for “free lut download” and you’ll have TONS of links to go. Thankfully, there are a wealth of free LUTs available online for download.
Getting some LUTsīefore we dive into TouchDesigner, we need a few LUTs we can use. This TOP can load LUTs as well as perform a lot more advanced colour grading. Luckily we’ve had an OpenColorIO TOP added to TouchDesigner that builds the whole framework right into our regular old TOPs. It’s similar to the new 3D file format USD but for colour management. OpenColorIO is a complete colour management framework that was developed for big studios and implemented in all the major softwares to help keep things consistent as pros are moving between different softwares. Looks cool? It is and it’s not hard to implement the same LUTs that pros use into our TouchDesigner projects to use with images or even live video using the OpenColorIO TOP. You can see the images I looked up online below for before/after comparisons of LUTs in action:
#LUT FILTER PRO#
Every pro film maker and photographer will surely have their pack of favourite LUTs or even their own created LUTs that they attribute to part of their style.
#LUT FILTER HOW TO#
It’s a giant table of numbers that tells the computer how to take an input colour value (also a number!) and transform it to a different output colour value (new numbers!). LUT (pronounced like “butt” but with an L at the beginning!) is an acronym for Lookup Table. These are the magic tools used to apply complex colour corrections and stylized effects quickly and easily and today I’ll show you how to add a LUT filter in TouchDesigner. If you’ve ever worked in the film or photography industry you’ll have heard of LUTs. Have you ever wondered how films get such beautiful colour looks? Have you tried to get Instagram-style filters in TouchDesigner? These kinds of things can be quite time intensive and difficult to do if you’re trying to manually use Level TOPs and can often end up in sprawling networks just to get what you thought was a simple effect.
