Camera

Capture photos and inspect detailed EXIF metadata from any available camera.

Full-screen live preview with camera picker (top-left) and flash toggle (top-right)

Overview​

The Camera tool provides a full-screen live viewfinder for every camera on your device. You can switch between lenses (wide, telephoto, ultra-wide, front, and more), toggle flash, capture a photo, and then inspect the resulting image along with its full EXIF, TIFF, and Apple Maker metadata. It supports both portrait and landscape orientations.

Table of Contents​

Controls​

When camera permission is granted, the live preview runs full-screen.

Top bar:

  • Camera picker (top-left): opens a dropdown menu to select from all available cameras.
  • Flash toggle (top-right): enable or disable flash for the next capture. The bolt icon turns yellow when flash is on.

Bottom:

  • Shutter button: large circular button to capture a photo.

Camera Picker​

Camera picker listing every available lens and camera

Tapping the camera picker opens a dropdown listing every camera discovered on the device. Available options vary by model but can include:

  • Telephoto — long-range optical zoom lens
  • Wide — standard wide-angle lens (selected by default)
  • Ultra-Wide — extended field-of-view lens
  • Dual Wide — dual wide-angle camera system
  • Front Camera — front-facing TrueDepth camera
  • Front Ultra Wide Camera — front-facing ultra-wide lens

The active camera is indicated with a checkmark.

Flash Toggle​

The flash toggle in the top-right corner switches between flash on and flash off. When enabled, the bolt icon fills yellow; when disabled, it appears as a slashed bolt in white. Flash availability depends on the selected camera — front cameras and some lenses may not support flash.

Orientation​

The camera tool adapts to landscape orientation automatically

The camera preview adapts to device orientation. The viewfinder rotates to fill the screen in both portrait and landscape, and captured photos are saved with the correct orientation metadata.

Taking A Photo​

Tap the shutter button to capture. Photos are taken at the device's maximum supported resolution. After capture, Lirum automatically navigates to the Photo Preview screen.

Photo Preview​

Photo Preview with Image Data tab showing file info and parsed camera metadata

The Photo Preview screen displays the captured image at the top and offers two tabs for metadata inspection:

  • Image Data — parsed, human-readable metadata organized into sections.
  • Raw Data — the full metadata dictionaries in their original form.

Image Data Tab​

Parsed metadata including camera model, ISO, flash status, lens model, and more

The Image Data tab organizes metadata into clear sections:

Basic file information:

  • File size (bytes)
  • Resolution (width x height)
  • Format (JPEG)

Parsed camera data:

  • Date & Time
  • Make and Model
  • Software and Host Computer
  • Focal Length (mm)
  • Aperture (f-number)
  • ISO
  • Exposure Time (formatted as fractions, e.g. 1/1258 sec)
  • Flash Used (detailed status such as "Flash did not fire, Compulsory flash mode")
  • Lens Model (includes full lens description, e.g. "iPhone 17 Pro Max back camera 6.765mm f/1.78")
  • White Balance (Auto or Manual)
  • Color Space

Additional metadata sections:

Additional metadata sections with TIFF, EXIF, and Apple Maker data
  • Other TIFF Data (resolution units, X/Y resolution)
  • Other EXIF Data (aperture value, brightness, exposure program, metering mode, scene type, shutter speed, pixel dimensions, and more)
  • Apple Maker Data
  • Other Metadata (color profiles, etc.)

Raw Data Tab​

Raw Data tab with collapsible sections for EXIF, TIFF, and Apple Maker dictionaries

The Raw Data tab presents the unprocessed metadata dictionaries in collapsible sections:

  • EXIF Data — full EXIF dictionary
  • TIFF Data — full TIFF dictionary
  • Apple Maker Data — Apple-specific proprietary metadata

Each section can be expanded or collapsed. Values are displayed in a monospaced font and are selectable for copying.

Permissions​

Camera access requires iOS permission.

  • On first launch, Lirum requests camera access through the standard iOS permission dialog.
  • If permission is denied or restricted, Lirum shows a permissions prompt with a button to open iOS Settings where you can grant access.

Notes And Limitations​

  • On visionOS, the Camera tool is unavailable.
  • Some devices have multiple rear cameras; which lenses are available may vary by device model and iOS version.
  • Photos are always captured at the device's maximum supported resolution.
  • The Camera tool does not include manual exposure, focus, or zoom controls — it focuses on capture and metadata inspection.
