See some of Denver Riddle’s 70 free LUTs in action in this short promo.ġ. You can hear them chat about that in more detail in this previous post I wrote about LUTS, over on .įor further reading this explanation from Abel Cine on the difference between LUTS, Looks and Scene Files is also worth a read. This is one of the reasons colorists like Patrick and the Coloristo’s are at pains to get people to understand that you can’t ‘slap a LUT on it’ and expect great results every time, you have to do more work than that. Over many different Insights and in many different ways Dan, Patrick and I have explained LUTs, how we use them, and best practices including some that I’ll go over again in this Insight, but that info is spread out across dozens of videos and articles here on and some of those articles are from a years ago (yes, we are entering our fourth year of operation)! This Insight is about avoiding the common mistakes/pitfalls you’re likely to make with Look Up Tables.
#CINEMA GRADE ACES UPDATE#
UPDATE – Mixing Light colorist and trainer Robbie Carman has put together an even more detailed primer on LUTS in this recent Mixing Light Insight. The problem is that if you have a bright shot next to a dark shot and you slap the same LUT on them, you will have two very different looking images come out the otherside because a LUT cannot account for differences in exposure. He gives the example of the ARRI Alexa Log-C to Rec 709 LUT, which takes a flat image and expands it out to make it look ‘normal’ for us (used to, as we are the Rec.709 colour space). Patrick goes on to explain the problems can occur when we use a creative LUT as if it were a technical LUT. Ĭreative LUTS – These types of LUTs can be generated in software, allowing, for instance, completely different grading apps to share looks between them. The end goal is to have the same image look perceptually identical on two different viewing devices. Technical LUTS – These types of LUTs are designed to transform an image from one colour space / gamut to another. He broadly divides LUTS into Technical LUTS and Creative LUTS.

In this post over on Mixing you can learn a little bit about the different types of LUTS as colorist Patrick Inhofer defines them. What are the different types of LUTS for? This short video from Ground Control Color will give you a good overall understanding of the premise of a LUT and is humorous, which is a bonus. In essence, what a 3D LUT does is take an input value and generate a new output value, for each and every RGB triplet. This explanation on LUTS from Light Illusion is also well worth a read and is also helpful on explaining 3D LUTS. This allows for greater control, for example, increasing contrast without increasing saturation. Here you can create “ a set of the combination of three inputs defining the combination of R, G, and B values not of one where each input refers to one unique output”. With a 3D LUT you have more control over transforming these values separately and in combination. So if you increase contrast in your image, you will increase saturation, because the values are tied together in the simple chart, take this and make it that. With a 1D-LUT you’ve got some control, but not that much control. I’ll paraphrase it as best I understand it. This explanation over on the Fuji film site is mildly technical, but still explains things to an accessible level of detail. What’s the difference between a 1D-LUT and a 3D-LUT? For example in the red channel use LUT A to make 1 = 7 but in the blue channel use LUT B to make 1=15. This can happen to the image over all or per colour channel (RGB). If the input is 0 make the output 5 – or whatever, these numbers are arbitrary, it is just a conversion matrix – take this, make it that. If you’re an editor into saving time, you might also be interested in this post on my favourite royalty free production music sites.Ī LUT is basically a table that says if the input is 1 make the output 7.

With the proliferation of the use of Look Up Tables (LUTS) in the production and post-production process, there’s never been a better time to understand what they are and how best to use them.īut if you don’t care about that and just want to get your hands on some free LUTS – scroll down!
