## What is LogBloom?

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.


## Version history (last 3 releases)

### 1.2 — 2026-08-20

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.

### 1.1 — 2026-07-04

This update focuses on speed, reliability, and polish.

Editor & Looks
  • Look previews are now rendered on your actual footage — the shelf and Library show each Look applied to your current frame instead of a generic icon.
  • Imports from Photos now show the clip's shoot date (or camera model) instead of a generic "Video" title.

Performance
  • Much faster LUT imports — .cube files now parse in a fraction of the time.
  • Smoother scrolling and lower memory use, with imports and thumbnails moved off the main thread.
  • Starter pack thumbnails are pre-generated on first launch, so the Library is ready right away.

Exports
  • The screen stays awake during exports, so auto-lock can't interrupt a long render.
  • Batch exports now survive being interrupted — reopen the app and pick up where you left off with Resume Batch.

Reliability
  • Fixed iCloud sync issues where renames, rule edits, and deletions could fail to sync between devices.
  • If a save ever fails, you'll now see an alert instead of silently losing the change.
  • Onboarding no longer replays when you install on a second device.

Also
  • New Help section in Settings: what LUTs are, where to find .cube files, and troubleshooting tips, plus quick links to support.
  • Accessibility improvements: VoiceOver support for the intensity slider and the before/after comparison divider.

### 1.0 — 2026-07-01
