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.

E-Log is short for Easy Log: recording in Log, made easy. Your iPhone can already record in Apple Log. E-Log is what makes it usable. Log keeps all the light and colour the sensor can see, but it looks flat and washed out until someone grades it. E-Log puts the grade on the monitor, live, while you shoot. You frame what you'll actually publish, not a grey approximation of it. WHAT YOU CAN DO • See your look live. Turn on the eye and the monitor shows the finished image. The file stays raw. • Or bake it in. One button and the clip comes out already graded, ready to publish with no edit. • Both, on the same take. Preview one look, export with another. Nothing is decided at the moment you press record. • Bring your own looks. Import any .cube LUT built for Apple Log. FULL CONTROL, ONLY WHEN YOU WANT IT Shutter, ISO and white balance in auto, manual, or any mix of the two. Shutter angle or speed. Automatic limits so auto never picks something you'd never pick. WHAT YOU NEED TO JUDGE AN EXPOSURE Waveform and histogram · zebra on highlights or midtones · focus peaking · framing guides for 9:16, 2.39 and more · horizon level. None of them is ever recorded into the file. YOUR CLIPS STAY YOURS Takes live in the app's own library, not in Photos: they are 10-bit files and the system would compress them. Export whatever you want, wherever you want, in Log or already graded. REQUIREMENTS E-Log needs an iPhone that can record in Apple Log (iPhone 15 Pro and later Pro models). The app checks your device at first launch and tells you straight away if it can't. SUBSCRIPTION E-Log is a subscription. Yearly and Monthly include exactly the same features (recording in Log, looks on the monitor, and exporting clips with the look baked in), and Yearly comes with a free trial. Cancel anytime in one tap. Downloading the .cube files themselves, to take your looks into DaVinci, Premiere or another camera, is a separate one-time purchase available to any subscriber once the free trial has ended.

Verdict

The call

The clearest difference is update cadence: E at every 2 days against LUT Lab's every 3 weeks. LUT Lab's advantage is device support (4 vs 1) and iOS requirement (15.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.
