Photo Delivery QA Utility

ShooterSync

Review multi-camera deliveries on one timeline.

ShooterSync is a macOS utility for photo delivery QA. It merges JPEGs from multiple cameras by EXIF capture time, then surfaces gaps, camera-level imbalance, and images missing usable timestamps.

Problem

Delivered photo files cannot be verified by appearance alone.

Multiple cameras, multiple folders, and multiple photographers.
Simply opening folders does not tell you whether the entire event was fully covered.

  • Critical time windows left uncaptured
  • Specific cameras stopped shooting
  • Images missing EXIF timestamps
  • Deliveries containing fragmented timelines

Timeline Integration

Review the entire event as a single chronological timeline.

ShooterSync merges photo files from multiple cameras into a single chronological timeline, allowing you to review the entire event at once.

Camera clock offsets can be corrected by selecting two images captured at the same moment.
If needed, you can copy and rename the photos in chronological order to a new delivery folder.

Delivery QA

QA features to verify delivery quality.

Gap Detection

Automatically detects capture-time gaps beyond a set threshold. Each gap is listed, so you can jump straight to the images before and after.

  • 11:42 – 11:58 16 min 03 sec
  • 14:07 – 14:29 22 min 14 sec
  • 17:31 – 17:45 13 min 51 sec

Camera Statistics

See each camera's shooting patterns at a glance: image count, first and last capture times, total duration, average interval, and longest gap.

Camera A 2,341 imgs
Camera B 1,893 imgs
Camera C 718 imgs
Max Gap 22 min

Unsupported Images

Images without a DateTimeOriginal tag are kept out of the timeline, flagged as Unsupported Images, and recorded in the QA Report.

  • screenshot_001.jpg

Keep a lasting record of delivery quality. Export your review as a QA Report in Markdown or TXT.

Contact Sheet

Contact sheets matching your delivery file numbers.

The printed numbers on the PDF contact sheet match your renamed files exactly. Referring to "Image No. 001" points everyone to the exact same file.

You can also regenerate the contact sheet alone using an existing delivery folder.

DEMO VIEW

Correct, inspect, and export — all in one unified view.

Correct camera time offsets and review photos merged by capture time. In the QA Summary, check gaps, images without EXIF timestamps, and camera statistics.

After reviewing the contents, run a chronological copy-and-rename with the corrected times.

Safety

Source files are never modified.

ShooterSync only creates new copies. Input files are never moved, overwritten, recompressed, or altered. EXIF metadata is never rewritten.

All processing happens locally, within the folders you select.

About the Maker

Why I made ShooterSync.

Takashi Kajihara ↗
Photographer / Filmmaker

Photos captured with multiple cameras may be in shooting order within each camera, but they do not form a single timeline across the delivery.

After shooting, developing, and selecting, the final step is to merge JPEGs from multiple cameras into a single continuous timeline and organize them into a numbered sequence for delivery. I made ShooterSync so that this final step could be handled as a tool rather than repeated manual work.

What matters is not which camera took each image, but that the recipient can handle the entire event as a single continuous timeline.

Who It's For

Was the event fully covered?

ShooterSync is designed for inspecting multi-camera coverage in professional event photography.

  • Event Production Companies

    Verify multi-photographer deliveries by timeline and shooting patterns for large-scale events.

  • Wedding / Bridal Companies

    Inspect full wedding and reception coverage to ensure no critical gaps exist.

  • School Photography Agencies

    Maintain delivered photo files across schools and schedules using precise file numbering.

  • Editorial Photo Desks

    Quickly verify the chronological order and coverage of editorial shoots before delivery.

  • Sports Tournament Operations

    Review a full day of shots from photographers in multiple positions without missing details.

  • Photography Studios

    Generate QA reports to document inspection details and prove delivery quality before sending files to clients.

Merge multiple cameras into one timeline — so gaps and clock offsets can be caught on the receiving end, too.

Scope

What ShooterSync does not do.

ShooterSync is a specialized utility and does not include the following features.

  • RAW processing / editing
  • Photo culling / selection
  • Rating / flagging
  • Digital Asset Management (DAM)
  • Lightroom alternative
  • Photo library manager alternative
  • AI image correction
  • Automatic image quality evaluation

ShooterSync is a dedicated QA utility for verifying the timeline and quality of delivered photos.

ShooterSync is for

Built for verifying, not organizing, delivered photo files.

  • Verifying delivery quality
  • Chronological timeline integration
  • Saving QA review records

Delivery Complexity

Delivery QA is more than one check.

Delivery data from multiple cameras and folders cannot be verified by looking at images one at a time. It requires comparing across cameras and running several checks across the whole set.

  • Camera clock offsets
  • Timeline consistency from start to finish
  • Capture-time gaps
  • Differences in capture volume between cameras
  • Images missing EXIF capture timestamps

Pricing

Getting delivery-ready — that's ShooterSync.

Free lets you review delivery data. Pro preserves the inspection as evidence and turns that review into delivery-ready output.
