LogBloom: LUT Video Grading
Cinematic LUT color grading
Free · Designed for iPad. Not verified for macOS.
Turn flat Apple Log and DJI D-Log footage into finished cinematic color on your iPhone—no desktop, no subscription. Stack LUTs, fine-tune, export to Photos.
LogBloom turns flat log footage into finished, cinematic color — entirely on your iPhone or iPad. Shoot Apple Log on iPhone or D-Log on a drone, drop the clip in, and get graded video back into Photos without ever opening a desktop editor.
No subscription. No cloud upload. Your footage never leaves your device.
GRADE WITH LUTs
• Apply .cube LUTs to any video or photo
• Stack multiple LUTs into a chain, each with its own intensity
• Reorder, blend, undo and redo — see every change live on your actual frame
• Save any combination as a reusable "Look"
BUILT FOR LOG
• Built-in Apple Log → Rec.709 and DJI D-Log → Rec.709 conversion, computed from the published color science — not guesswork
• LogBloom always applies the log conversion before your creative look, so colors stay correct no matter the order
• HDR/HLG clips are tone-mapped to SDR, and the app tells you when that happens
FINE-TUNE
• Post-grade adjustments: exposure, contrast, saturation, temperature, tint, and vibrance
• Hold to compare against the original, or use the split-screen wipe
• Built-in histogram scope
• Save any frame as a graded HEIC still
SMART SUGGESTIONS
• LogBloom reads your clip's camera and color profile and surfaces the right conversion LUT first
• Works for photos too, using EXIF camera data
EXPORT THAT KEEPS YOUR METADATA
• Export to Photos or Files as MOV or MP4, HEVC or H.264, up to 4K
• Original creation date and GPS location are preserved on the exported clip
• Size estimate before you export
• Batch mode: grade up to 50 clips, or apply one grade to a whole batch at once
PHOTOS TOO
• The same LUT pipeline and adjustments work on still photos, with EXIF and GPS preserved
YOURS, EVERYWHERE
• Your LUTs and Looks sync privately across your devices via iCloud
• Share a Look as a single .logbloomlook file — it carries the LUTs inside it
• No account, no server, no tracking of your creative work
LogBloom is the fastest way to take iPhone and drone log footage from flat to finished, right where you shot it.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
This update adds pro exposure tools, support for more cameras, and a much stronger batch workflow.
Cameras & Log Formats
• Sony S-Log3 and Fujifilm F-Log2 are now detected automatically, with matching conversion LUTs added to your library.
• Looks without their own camera rules are now suggested based on the LUTs inside them.
Exposure Tools
• The histogram is now live — it updates during playback and reflects exactly what's on screen.
• New false color and zebra overlays for judging exposure at a glance. Both are preview-only and never affect your export.
• A metadata row above the video shows color profile, resolution, frame rate, and codec.
Library
• Favorite your LUTs and Looks, and organize them with tags — new filter chips narrow the Library instantly.
• Thumbnails now show each LUT applied to real footage instead of a color chart.
• Open .cube files and shared Looks directly from Files, Safari, or AirDrop.
• Deleting a LUT or Look now shows you where it's used first.
Batch Grading
• Copy and paste grades between clips in the queue, or apply one grade to everything remaining.
• Export All replays each clip's own saved grade.
• Optionally delete originals after a verified export — with a confirmation first, and a summary of what was deleted or kept.
Exports
• HEVC exports are now 10-bit by default for cleaner gradients and less banding, with a Compatible mode if you need the previous behavior.
• A Format & Quality section collects codec, resolution, and a bitrate override.
Editor & Onboarding
• Exposure, temperature, and tint now apply before the LUT, so highlights hold detail instead of clipping.
• Onboarding can open a bundled sample clip, so you can try a grade before importing anything.
• Cleaner editor chrome, a centered layout on iPad, and plainer wording throughout.
Reliability
• Fixed a playback issue where a clip could refuse to play after switching back and forth between videos.
• Fixed a false "Export failed" message and a stuck share screen when LogBloom only had permission to add photos.
• Recents now clears itself when a video is deleted from Photos — and keeps your grade if the video was only hidden or is still recoverable.
• Imports show progress, can be cancelled, and download iCloud placeholder files automatically.
Also
• Accessibility and VoiceOver improvements throughout, plus keyboard shortcuts listed in Settings › Help.
