LUT Lab vs Lutter

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.

Give your videos a cinematic look. Lutter brings creative filters, LUTs, and precise color controls together in one video color grading workspace. Grade video on iPhone and iPad. Start with an everyday clip, a travel video, or your next short film. Shape the mood, compare your edits, and carry a consistent look across your videos. Import, grade, and export without a watermark. MORE ROOM TO CREATE On iPad, a larger preview and dedicated landscape controls give color wheels, curves and LUT browsing room to breathe. Add warm halation and soft bloom to highlights. Temporal noise reduction is available on supported devices with iOS/iPadOS 26 or later and compatible footage. BUILD YOUR LOOK • Apply built-in looks or import your own .cube LUTs. • Stack LUTs and independent color adjustments in the order you want. Adjust color before or after a look, change its strength, or bypass a stage to compare. • Refine exposure, contrast, saturation, vibrance, white balance, and tint. Use color wheels and tone curves for finer control, then add film grain. • Get a starting point with Auto Exposure, Auto White Balance, and a white-balance picker. COMPARE AND REUSE COLOR • Save a video frame as a reference, or import a reference photo from Photos or Files. Compare while you grade, including HDR references. • Reapply color settings from saved video references to other clips. Imported photos provide a visual reference for your own adjustments. • Copy and paste color settings between projects, or apply a look to multiple clips for a consistent shoot. SEE WHAT YOU ARE CHANGING • Compare the original and graded image with a split preview, or work in full screen. • Check exposure and color with a live histogram, floating waveform, vectorscope, and false color. • View HDR previews using the extra brightness of supported displays. FINISH YOUR VIDEO • Trim the start and end, crop, rotate, flip, straighten, and choose an aspect ratio. • Reduce handheld shake with stabilization. Use Skin Tone Fix to reduce unwanted magenta in skin. • Export up to 4K with H.264, HEVC, or ProRes 422 options. Control resolution, frame rate, and bitrate. • Export Rec.2020 HLG or PQ HDR with compatible 10-bit HEVC or ProRes settings. • Export supported color adjustments as a .cube LUT to reuse in other grading tools.
