LUT Lab

A LUT (Look Up Table) is a simple file that lets you change the colors, tone, and contrast of photos/videos - like a universal color preset, compatible between different apps.

LUT Lab is a handy tool that lets you visualize LUTs, use them to process any photo of your choice, and export to/from the most common LUT formats: .CUBE and HALD.

It is a nifty companion tool for photographers and videographers, featuring:

- Minimal and information dense interface

- Full, interactive 3D cube visualizer

- Before/After photo split viewer; load your own photos, export a LUT-processed version at native resolution.

- Support for .CUBE (any size on input, up to 65×65×65 export) and HALD (TIFF/PNG, any rank) formats

- Convert from .CUBE to HALD and from HALD to .CUBE; optionally resample .CUBE files for maximum compatibility with other apps

- Supports desktop class features on iPad + Mac: multiple windows, drag & drop, keyboard shortcuts, open .CUBE files into LUT Lab straight from Finder/Files, etc.

- Multiple color themes (one time in-app purchase required)

- Extremely small app size: tons of functionality packed into only a couple megabytes.

- Respects your privacy: no 3rd party libraries or tracking. Uses the latest iOS APIs so you only have to give minimal permissions for loading & saving files.
