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.

Verdict

The call

LUT Lab's advantage is update cadence (every 3 weeks vs every 2 months) and device support (4 vs 2). On price, rating, review sentiment and ads there is nothing between them.
