LuttieAI Color Grading Is Here — And It Exports a .cube LUT
Luttie's new AI Grade feature lets you describe a cinematic look in plain text and get three ready-to-export .cube LUTs in seconds. Here's how it works and why it matters.
Color grading has always required a specific kind of fluency — the ability to translate a visual feeling into slider positions, curve shapes, and color wheel offsets. Most people have a sense of what they want ("something cinematic, a bit warm, with teal in the shadows") but bridging that feeling and the technical execution takes practice.
AI Grade closes that gap.
What AI Grade Actually Does
When you open the AI Grade panel in Luttie, you type a description. Something like:
"warm cinematic with teal shadows"
The AI returns three distinct color grading variants — not filter thumbnails, not mood board suggestions. Real grading parameters: temperature values, contrast adjustments, color wheel settings for shadows, midtones, and highlights, and RGB curve shapes.
Each one is immediately exportable as a .cube LUT. You can also apply any look to your canvas and every parameter loads into the normal sliders — curves, color wheels, basic correction — so you can push or pull anything manually.
It Sees Your Image
This is the part that makes it genuinely useful rather than just a novelty.
Before generating grades, the AI reads your actual image. It analyses your existing tones, exposure level, and color cast. If your shot is already warm, it won't add more warmth. If your shadows are already deep, it won't crush them further. It grades from where you are, not from a blank starting point.
This is important. A lot of AI grading tools ignore the source material and apply a generic look regardless of what's actually in the frame. That's fine for Instagram filters. It's not useful for LUT creation, where the goal is a grade that works with your specific footage.
Three Interpretations, Not Three Variations
Each prompt returns three meaningfully different looks, not three versions of the same grade.
For "warm cinematic with teal shadows", you might get:
- One with a strong orange-teal split, lifted blacks, and a subtle S-curve
- One with warmer midtones, a softer shadow hue shift, and more contrast
- One that leans into the faded film direction — lifted blacks, reduced saturation, cooler teal
The point is that "warm cinematic with teal shadows" is an intention, not a specification. Different colorists would execute it differently. AI Grade gives you three executions to choose from.
The Workflow
- Upload your image or video frame
- Open the AI Grade panel
- Type your look description (or pick one of the suggestions)
- Get three looks in about 5–10 seconds
- Apply any of them to your canvas, or download directly as
.cube
If you apply a look and want to adjust it, all the parameters are live in the editor. You're not locked into anything. The AI sets the foundation; you finish it.
Who This Is For
Photographers who want to turn a color feeling into an exportable LUT for batch editing in Lightroom or Capture One. Describe the mood of your portfolio and get a consistent grade to apply across a shoot.
Video editors who need to build a look quickly — especially when working on commercial or social content where speed matters more than obsessive manual precision. Type your reference look, apply it, export the LUT, drop it in DaVinci Resolve.
Beginners who know what a cinematic look should feel like but don't yet have the technical vocabulary to build it from scratch. AI Grade is a way to learn — apply a generated look and study what it actually did.
Anyone who uses reference images — AI Grade works especially well when you describe something specific: a film, a photographer's work, a particular era. "Kodachrome summer film grain", "1970s Wim Wenders palette", "cold northern European documentary". The AI has broad visual and cinematic knowledge.
What It Isn't
AI Grade is not a colour matching tool. If you want to match an exact reference image, Luttie's Color Match feature is the right tool — it analyses the statistical color distribution of a reference photo and builds a LUT specific to that relationship.
AI Grade is for direction. When you have a feeling but not a reference. When you want exploration. When you want three different answers to the same question.
