Are LUT’s Killing Creativity And ERODING Skills?

I see this all the time “which LUT should I use to get this look” or “I like that, which LUT did you use”. Don’t get me wrong, I use LUT’s and they are a very useful tool, but the now almost default reversion to adding a LUT to log and raw material is killing creativity.

In my distant past I worked in and helped run  a very well known post production facilities company. There were two high end editing and grading suites and many of the clients came to us because we could work to the highest standards of the day and from the clients description create the look they wanted with  the controls on the equipment we had. This was a digibeta tape to tape facility that also had a Matrox Digisuite and some other tools, but nothing like what can be done with the free version of DaVinci Resolve today.

But the thing is we didn’t have LUT’s. We had knobs, dials and switches. We had to understand how to use the tools that we had to get to where the client wanted to be. As a result every project would have a unique look.

Today the software available to us is incredibly powerful and a tiny fraction of the cost of the gear we had back then. What you can do in post today is almost limitless. Cameras are better than ever, so there is no excuse for not being able to create all kinds of different looks across your projects or even within a single project to create different moods for different scenes. But sadly that’s not what is happening.

You have to ask why? Why does every YouTube short look like every other one? A big part is automated workflows, for example FCPX that automatically applies a default LUT to log footage. Another is the belief that LUT’s are how you grade, and then everyone using the same few LUT’s on everything they shoot.

This creates two issues.

1: Everything looks the same – BORING!!!!

2: People are not learning how to grade and don’t understand how to work with colour and contrast – because it’s easier to “slap on a LUT”.

How many of the “slap on a LUT’ clan realise that LUT’s are camera and exposure specific, how many realise that LUT’s can introduce banding and other image artefacts into footage that might otherwise be pristine?

If LUT’s didn’t exist people would have to learn how to grade. And when I say “grade” I don’t mean a few tweaks to the contrast, brightness and colour wheels. I mean taking individual hues and tones and changing them in isolation. For example separating skin tones from the rest of the scene so they can be made to look one way while the rest of the scene is treated differently. People would need to learn how to create colour contrast as well as brightness contrast. How to make highlights roll off in a pleasing way, all those things that go into creating great looking images from log or raw footage.

Then, perhaps, because people are doing their own grading they would start to better understand colour, gamma, contrast etc, etc. Most importantly because the look created will be their look, from scratch, it would be unique. Different projects from different people would actually look different again instead of each being a clone of someone else’s work.

LUT’s are a useful tool, especially on set for an approximation of how something could look. But in post production they restrict creativity and many people have no idea of how to grade and how they can manipulate their material.

New s709 LUT For The FX9 That’s Less Green Than The Sony LUT.

Many users of the FX9 that have been shooting S-Log3 are finding that when they add the standard Sony version of the s709 LUT that their pictures have a slight green tint. I believe that this is because originally the s709 LUT was designed for the Sony Venice camera and the FX9 is very slightly different.  I recently created an experimental LUT to minimise this tint but some people found this tended to push some images slightly magenta.

So I now have a new version of the LUT which really does help combat the green tint. The difference between this LUT and Sony’s original s709 LUT is very small. The idea isn’t to create a new look, just to help get rid of the tint. So you won’t see a big difference, it’s subtle, but I think it really is better.

Click Here to download the ACs709 For FX9 LUT set.

Note: These LUTs are for S-Log3 and SGamut3.cine from the FX9. As usual I have include different versions of the LUT. There are 65x LUT’s suitable for grading as well as 33x LUT’s for monitors or grading software that doesn’t support the higher quality 65x LUTs. There are also minus1 and minus2 LUTS that have 1 and 2 stop exposure shifts for footage that has been shot brighter than the base exposure. In addition I have include the same LUTs but with Legal range input levels for use on Atomos and other recorders that record ProRes in using Legal Range.

Please feel free to share a link to this page if you wish to share these LUT’s with anyone else or anywhere else. But only share via a link to this page please.

If you find these LUT’s useful please consider buying me a coffee or other drink. To make a contribution please use the drop down menu here, there are several contribution levels to choose from.

S709 LUT (Venice Look) And 709(800) For LEGAL RANGE PRORES S-Log3 On Atomos and other Recorders.

As noted in my previous post there can be some issues with the way ProRes is recorded on many external monitors as a legal range files rather than Data Range.

Another side effect of this is that LUT’s designed for post production as well as most camera LUT’s don’t work correctly in the monitor. So even when you apply the same LUT in the camera as in the monitor the images look different.

To address this I am providing here 2 sets of LUTs for S-Log3 and SGamut3.cine designed to match the built in s709 and 709(800) Luts included in many Sony cameras. These LUTs are specifically for external recorders and should not be used in camera. When you use these LUT’s the pictures on the monitor should now match the the images in the cameras viewfinder when the built in  LUT has been applied.

You will find 3 LUTs of each type. One for the base exposure, one for footage exposed 1 stop brighter (minus1) and one for footage exposed 2 stops brighter than base (minus2).

As always (to date at least) I offer these as a free download available by clicking on the links below. Try them before you decide then pay what you feel is fair. All contributions are greatly appreciated and it really does help keep this website up and running. If you can’t afford to pay, then just download the LUT’s and enjoy using them, tell your friends and send them here. If in the future you should choose to use them on a paying project, please remember where you got them and come back and make a contribution. More contributions means more LUT offerings in the future.

If you want to share the LUT’s please do so by a link to this page. You may not sell or distribute these LUTs anywhere without my prior consent.

Experimental s709 LUT Specifically for the FX9.

I’ve had a few people comment that they feel that the PXW-FX9 is a touch green when you shoot S-Log3 and SGamut3.cine and then add the standard Sony s709 V200 LUT in post. So I have created a slightly modified version of the s709 LUT that I have tweaked specifically for the FX9. You can download it using the like below. Do let me know what you think.
