LUT Generator is a browser-based color workflow for photographers, filmmakers, video editors, and creators who want to explore a reference-inspired look without treating an attractive preview as a finished grade. Start with an original photo or an SDR video frame, add a reference image, and compare the result on meaningful parts of the picture rather than judging only its overall mood.

Local color matching and PNG previews are free. Optional AI assistance works with reduced previews; original media stays local. Custom .cube exports use credits, so users can evaluate a look before deciding whether to export a reusable color table. The interface is useful for experiments involving contrast, tonal balance, and color relationships, not for guaranteeing that a reference image's lighting or composition will transfer.

A practical test includes natural skin tones, neutral surfaces, smooth gradients, bright highlights, and dark textures. Check more than one frame and reduce the strength when needed. Reusing a LUT also requires compatible input assumptions: this workflow is designed around SDR imagery and is not a replacement for camera-specific Log transforms, HDR tone mapping, or a properly managed color pipeline. The website offers an accessible starting point for learning, comparison, and repeatable creative checks.
