LogBloom: LUT Video Grading

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.
