Glossary

Summary

Every acronym and feature name the user guide uses, defined in plain language. Entries cluster by feature (culling terms together) and run alphabetical-ish in between. Cross-references link to the page where each feature lives.

• Metadata standards

  EXIF, IPTC, XMP, and ExifTool. The standards and tools that move keywords, captions, GPS, and camera details between apps.

• File formats

  JPEG, WebP, AVIF, HEIC, and RAW. What the file extension on your photo means.

• Jade GT vocabulary

  Stage, Commit, Triage row, Privacy Scrub, Sync Ritual, Stock Readiness, and other terms the guide uses repeatedly.

AVIF

AV1 Image File Format. A modern image format that produces the smallest files at the same visible quality. Slower to save than WebP. Supported in every modern browser.

Commit

The final step that writes staged edits to disk. Triggered from the Review Hub. Until you commit, the original files stay untouched.

Compare / Survey

The side-by-side grid (2 to 4 photos) with synced pan and zoom, opened by pressing C when 2-4 photos are selected. Same culling tool Lightroom calls Compare (2-up) and Survey (n-up). See the Preview tab Compare and Survey section.

Direct Save

The Pro-only saving mode that writes metadata changes back to your original files in place. Needs a Chromium browser (Chrome, Edge, Brave, Arc, or Opera) and folder-write permission.

EXIF

Exchangeable Image File Format. Technical camera data embedded in a photo: model, lens, shutter speed, ISO, focal length, and GPS coordinates.

ExifTool

The open-source tool for reading and writing photo metadata. Jade GT runs it inside the browser through WebAssembly.

Export Mode

The saving mode that produces fresh copies (or a ZIP archive) of your photos with updated metadata. The default on Safari, Firefox, and mobile browsers.

File System Access API

The browser API that lets a web app read and write files on your computer with your permission. Direct Save needs it. Available in Chromium browsers; missing on Safari, Firefox, and every mobile browser.

Free tier

Jade GT's no-cost tier: up to 10 photos per batch, 20 edits per day, Export Mode only, no RAW support. See Subscriptions & Pro Features for the full list.

Geocoding

Looking up a place name (city, region, country) from GPS coordinates, or coordinates from a place name. Jade GT uses MapTiler as the main service and falls back to OpenStreetMap's Nominatim.

GPX

GPS Exchange Format. The XML file phones and handheld GPS units write for a recorded track. The Mobile GPS Logger exports one when you finish a session.

HEIC

High Efficiency Image Container. Apple's default photo format on iPhone since 2017. Smaller than JPEG at the same quality. Jade GT reads and writes it on every platform.

Hierarchical keyword

A keyword stored with its parent path, separated by vertical bars (Travel|Iceland|Reykjavik). Lightroom and Bridge keep the parent path in their dedicated keyword field. Jade GT also writes each bare keyword into the standard keyword field, so other apps still see the same words. See the Tags tab hierarchical keywords section.

IPTC

International Press Telecommunications Council standard. The descriptive metadata block: captions, keywords, copyright, creator, location, and subject codes. Stock agencies read it.

JPEG (JPG)

The most widely supported photo format. Lossy: every save loses a little detail. Jade GT can read and write JPEG everywhere, but converting to WebP or AVIF preserves more quality.

Maybe flag

The third flag state, alongside Pick and Reject. The Maybe flag is the photographer's "I don't know yet" bucket. Press M (or click the ? button in the triage row) to mark a photo Maybe; it stays out of Pick and Reject views until you re-decide. Filter for Maybes only from the library filter chip strip.

Map Studio

The Pro full-screen map workspace, opened from the small map's corner button on the Location tab. Three tabs (Search, Tracks, Library), bigger sliders, and extra overlay tools.

Match Window

The maximum allowed time gap between a photo's timestamp and a GPX track point during GPX matching. Default 30 minutes; adjustable from the Match Preview slider.

Phone Metadata

The Pro feature that sends GPS, capture time, and IPTC fields from your phone to a desktop session with a 6-character code. See Phone Metadata. Earlier docs and code comments use the old name "Metadata Bridge"; same feature.

.jadeworkspace file

A plain-JSON file with your presets, keyword groups, rename patterns, pinned locations, and default toggles. Save it from Phone Metadata → Export and import on another computer so your bench setup follows you. See the Workspace handoff section.

.jadesession file

A plain-JSON file that bundles the decisions made on a single shoot: picks, color labels, captions, and coverage state. Photos themselves are not in the file; the other computer needs the same source folder. Jade GT matches photos by filename, size, and modified date, so the two computers do not need any shared internal labels. Distinct from .jadeworkspace, which carries presets and settings. See the Session handoff section.

Live Pair

The same-network device pairing that opens a direct connection between two Jade GT tabs and pushes a workspace across without going through a file. Trigger from Phone Metadata → Live Pair or the Command Palette. See Live Pair.

Mobile GPS Logger

The Pro feature that turns your phone into a GPS track recorder for field shoots. Pair the recorded track with a GPX match on the desktop. See Mobile GPS Logger.

NewsCodes

Standardised 8-digit IPTC subject codes that stock agencies and news organisations use to classify photos by topic.

Near-duplicate grouping

Jade GT's burst-frame culling tool. Jade GT builds a small fingerprint for each photo, then groups photos with similar fingerprints. Runs in your browser, no AI. See the Find near-duplicates section.

No AI Training flag

The metadata tag Jade GT writes that tells other apps a photo is off limits for AI training. On by default. Turn it on or off from the Photos column header or the Command Palette. See the Review Hub no AI training flag section.

Plus Code

Google's open location code. A short string like 84QV+CW that points to a 14m by 14m square anywhere on Earth. Useful for places without a street address. The Location tab accepts Plus Codes in the paste field.

Privacy Scrub

The full-metadata purge in EXIF Info. Removes GPS, camera identity, timestamps, IPTC and XMP fields, and embedded thumbnails in one staged operation.

Pro tier

Jade GT's paid tier ($9.99/month or $89.99/year). Unlimited batches, unlimited daily edits, Direct Save, RAW with XMP sidecars, Map Studio, batch Stock Readiness, project persistence, and the Mobile GPS Logger. See Subscriptions & Pro Features.

RAW

The unprocessed sensor data your camera writes. Each manufacturer has its own format (.CR2, .CR3, .ARW, .NEF, .ORF, .DNG, and 500+ more). Jade GT reads RAW on the Pro tier and writes metadata into an XMP sidecar.

Stage

Holding an edit for the next commit. Jade GT never writes to disk as you type; every edit stages first. A pulsing dot on the tab marks staged work.

Cull Mode

The full-screen single-focus culling workspace. Active photo fills the screen, top bar shows live progress, bottom strip shows the active frame's burst. Open it from the Command Palette (Cmd+K then Open Cull Mode). See Cull Mode.

Candidate-reject hint

The soft red dotted ring Jade GT puts on the other frames of a stack when you reject one frame inside it. It is not a rejection. It flags the rest of the burst for a second look. Press X on a hinted frame to confirm or U to clear. The hint clears on its own when you change the original frame's flag away from Reject. See Photo Stacks.

Stack

A group of burst-shot photos collapsed into a single card. Two photos belong in the same stack when they were captured within three seconds of each other AND share a visual fingerprint. The earliest frame is the keeper. Pressing P, M, X, or U on a collapsed keeper applies to every frame in the stack. See Photo Stacks.

Segment (coverage)

A contiguous slice of a shoot. Jade GT splits by capture-time gaps of ten minutes or longer. The Coverage panel in Cull Mode shows picks and rejects per segment so the photographer can spot under-coverage before they leave the venue. Default labels are Segment 1, Segment 2, and so on. Click a label to rename ("Getting Ready", "Ceremony", "Reception").

Coverage checklist

A free-form shot list per project. Type a shot to track ("cake cut", "first dance"); the item auto-ticks when a pick lands with a matching keyword, description, or headline. Lives in Cull Mode and persists across reloads.

Soft (auto-flag)

Jade GT's "soft focus" badge. A sharpness score on a small grayscale copy of the photo. The bottom 10% of each stack gets the badge. Points your eye only. Pick or reject is still your call. See the Cull Mode auto-flag badges section.

Bright / Dark (auto-flag)

Jade GT's exposure badges. Bright triggers when 25% or more of the pixels sit at pure white. Dark triggers when 25% or more sit at pure black. Useful for silhouettes and accidental flashes, less useful as a verdict.

Burst N (auto-flag)

Jade GT's "big stack" badge. Triggers on any stack with 8 or more frames. The badge invites you to open the stack in Cull Mode or Compare and thin it.

Stock Readiness

Jade GT's live score for how complete your photo's metadata is against the active stock-agency profile (Adobe Stock, Shutterstock, Getty, or General). See the Stock Readiness dashboard.

Sync Photo

The single photograph you take of the Mobile GPS Logger's UTC clock with your camera. Jade GT compares its EXIF time against the visible UTC pixels to find your camera's clock error.

Sync Ritual

The end-to-end workflow of photographing the Mobile Logger's UTC clock, recording your track, and finding the camera's clock error for a clean GPX match. See Mobile GPS Logger.

Triage row

The flag, color label, and star-rating control at the top of the Preview and Tags tabs. Catalog values only; never written to EXIF.

WebAssembly (WASM)

A way to run code from other languages (like ExifTool's Perl engine) inside a browser at near-full speed. Jade GT uses WebAssembly so metadata writing runs on your device without a server.

WebP

A modern image format that lands between JPEG and AVIF. Files are nearly as small as AVIF, but save several times faster. The safe default for most batches.

XMP

Adobe's Extensible Metadata Platform. A modern wrapper around IPTC and EXIF data, used inside files and in sidecar .xmp files.

XMP Sidecar

A separate .xmp file stored next to a RAW image, holding the metadata Lightroom and Capture One read. Protects the original RAW from being modified.
