Description

I tried with LUTCalc and I even have solarized images with 17x17x17 too. Will dig this week-end & will try Toms’ Luts too. Keno40 October 10, 2016. LUTCalc is an open source Javascript online web app I have developed to generate, analyse and visualise 1D and 3D LUTs for use with modern video cameras. It is also available as paid offline Mac OS X and Google Chrome apps from the Mac App Store and Google Web Store. Ben’s LUTCalc – 1D & 3D Cube LUT Calculator v2.1 has all sorts of goodies, such as Grading LUTs and Camera LUTs, Recorded Gamma, Output Gamma, CineEI ISO, Stop Correction, ASC-CDL, Knee Levels, Black Level / Highlight level, and you can even import your LUTs to look at and work on with the LUTCalc. I’ve used LUTCalc to create an SLog3 to LC709A LUT in the past. With the various customization features it has, it’s very simple to add a gamma tweak.

This is a collection of 20 look-up tables (LUTs) that will help you get the look of 20 acclaimed films.

LUTs are like magic brushes that paint your video or photos to give them a specific look. It’s a simple process of dragging and dropping each LUT onto your digital images, to see if you like the look that it creates. That’s it!

Here are the twenty films:
• 300
• Amélie
• The Assassination of Jesse James by the Coward Robert Ford
• Black Hawk Down
• Children of Men
• Citizen Kane
• City of God
• Deer Hunter
• Eternal Sunshine of the Spotless Mind
• The Girl with the Dragon Tattoo
• Gladiator
• The Matrix
• O Brother, Where Art Thou?
• Road To Perdition
• Saving Private Ryan
• Saw
• Schindler’s List
• Sicario
• Sin City
• Transformers

Each LUT can be used on its own, or in combination with traditional color grading tools, to further customize each look.

The product comes with an instructional video, plus additional references (YouTube videos) for those who don’t have the experience of using LUTs.

Compatible with standard video and most LOG (flat) profiles!

Famous Movies LUTs work with Rec.709 footage, which is the standard color space used by digital video and stills cameras. So if you shoot standard video, then you can directly apply the Famous Movies LUTs to your footage.

For those filming in flat profiles, the package includes additional LUTs that go straight from a flat LOG profile to the Famous Movies LUTs – eliminating the need to first convert to Rec.709.

The most popular LOG profiles are supported, namely: C-Log, D-Log, S-Log2, S-Log3, V-Log and V-Log L, as well as RAW and the Film profile of the BlackMagic Design URSA Mini 4.6K and Pro cameras.

If you use a different profile, you will just need to go to your camera manufacturer’s website to download a free LUT for converting to the standard Rec.709 color space.

Use these LUTs in-camera and on external monitors to preview the color grade!

These LUTs can be used on monitors and cameras that support LUTs, for example the Atomos Inferno; the Panasonic GH5.

Certain cameras (ex. Sony FS7) require a conversion to a compatible format. You can use the free utility LUTCalc to do this, and it’s available here.

For the Panasonic GH5 and the Atomos Inferno, our package already includes the compatible format (i.e. there is no need to use the LUTCalc utility).

Supported computer applications

To use the Famous Movies LUTs, you will need one of the following applications:

I was just involved in a discussion on creating IDTs for color grading in ACES cct in Resolve 14 when there is no built-in IDT. Or if the existing IDT isn't ideal.

Here's the process that I worked out:

When there is no IDT specified in the project and the clip, then Resolve expects the data to be in linear gamma and AP0 gamut. An input LUT can be applied before Resolve translates the clip to ACES cct color space. Thus a LUT that can translate the camera data into linear / AP0 is a proper replacement for an IDT.

This can easily be achieved in LUTCalc (https://cameramanben.github.io/LUTCalc/). To test this theory I took a clip and set the default Slog3/S-Gamut3.Cine IDT and took a screen grab for reference. I then created a custom LUT with these settings in LUTCalc. I set the clip's IDT to None and added the new LUT as the input LUT for the clip.

As seen below, the resulting image matches the reference images from the original IDT, suggesting that the two operations are equivalent.

This now opens the opportunity to make additional customizations to this input LUT to taste, or create a LUT that matches the camera specifics of unqiue cameras.

Based on this article, the other option is to create a DCTL script: http://acescentral.com/t/adding-idts-to-resolve/161/2. A DCTL script has the advantage that it's precise math rather than interpolated lookup table. The code in a DCTL script matches the math precision the built-in IDT use.

Lut Calculator

Using the Sony SLog-3 IDT and converting it to a DCTL file, which then is placed into the LUT folder and used instead of IDT or Input LUT also creates an equivalent image. In fact it creates an exact match when using a reference wipe, whereas the input LUT yields minor variations, presumably based on the less precise math or LUTCalc having slightly different input values.

Note that DCTL scripts require the studio version of Resolve.
