01 · Workflow

Three steps. Any editor. A real 3D LUT.

A HALD is an image that holds every color of a 3D LUT. Whatever your photo editor does to it, LUT Generator reads back and writes as a LUT you can drop on any clip.

A neutral HALD image: a grid of every color, from black to white
Step 1

Generate a HALD

One click, choose a destination folder. LUT Generator writes a neutral HALD image ready to be graded.

Step 2

Grade it anywhere

Apply a Lightroom preset, a Capture One style, Camera Raw or your own curves. Save as PNG, TIFF or JPG, without compression.

Step 3

Convert to LUT

Select your graded HALDs, pick a format and a size. You get a 3D LUT that reproduces the look on photos and video.

Convert HALD to LUT window listing two input files, output format .CUBE or .3DL and LUT sizes 17 to 65
02 · Convert

Every setting in one window, every file checked.

Drop in as many HALDs as you like, choose the output once, and let the batch run.

Files checked before conversion

Each HALD is validated as you add it. A warning flags files that may give a degraded LUT, such as compressed JPGs, before you waste a render.

Five sizes: 17, 32, 33, 64, 65

33³ is the everyday standard, 65³ for maximum precision, 17³ for monitors and cameras, 32³ and 64³ for apps that ask for them.

.CUBE or .3DL

The two formats read by virtually every editing, grading and compositing app.

Progress you can follow, and stop

Pick a destination folder, watch each file go through, cancel at any moment.

A LUT only maps colors. Effects that depend on position or texture would corrupt it.

Questions

Is it really free?

Yes. Enter $0 on Sellfy and download. Paying any amount you like supports the developer :-)

Which apps can grade the HALD?

Any app that opens and exports PNG, TIFF or JPG: Lightroom, Photoshop, Capture One, Affinity Photo, Pixelmator and more.

Why a warning on my JPG?

Compression alters the HALD's colors and can introduce artifacts in the LUT. Export PNG or 16-bit TIFF for the cleanest result.

Which LUT size should I choose?

33³ fits nearly every app. Choose 65³ for maximum precision and 17³ for monitors or cameras that need small LUTs.

How do I check my LUT?

Open it in LUTs Previewer to see it on your own footage with scopes, and repair it if needed.
