PLUMB / USER GUIDE

Your first shot.
Straight to it.

Start with a photograph. Plumb corrects perspective on your iPhone and keeps the original intact. Here are the essentials, from shutter to saved photo.

Start here

  1. Turn correction on. Take a photo.
  2. Open it. Compare with the original.
  3. Save a copy to Photos or share it.

Button positions below refer to portrait orientation. Free allows 10 successful saves of distinct corrected photos per device per UTC calendar month; failed and repeat saves do not count again. At the limit, automatic correction turns off; original capture and existing local photos remain available.

Take your first photo

Open Plumb and allow camera access when asked.

  1. Turn on correction. Check that the top-left control reads CORRECT ON. Tap it to switch correction on or off.
  2. Frame and shoot. Choose a zoom option above the shutter, leave room around the building, then tap the white shutter button. The timer control offers Off, 3 s and 10 s.
  3. Review this shoot. Tap the thumbnail strip beneath the shutter to open Current Shoot. For your full collection, use the Library icon at bottom left.

See what changed

Tap a photo in Current Shoot or Library to open the full-screen viewer.

  1. Compare. Use the perspective-shaped Compare with Original button in the bottom toolbar. Tap again to return. It is inactive when you are already viewing the original.
  2. Choose a version. Open the top-right menu → Photo Version. Choose Original, Auto Corrected, or Edited when available. Photo Information opens the image details.

Editor · Refine your photo

  1. Open Editor

    Open a photo from Library or Current Shoot, then tap the pencil in the viewer. Editing is non-destructive: the original and automatic correction remain available.

  2. Editor controls

    The photo remains the main working area. Cancel, Undo/Redo and the full-edit Done control are at the top; tools and their adjustment controls are below. Completing a Crop or Keystone adjustment is not the same as saving the full edit.

  3. Crop

    Tap Crop. Drag the frame or its edge/corner handles; pinch to scale the photo beneath it. Choose Free, Original, 1:1, 16:9, 4:3 or 3:2. Portrait photos show the corresponding reversed ratios. The bottom Done accepts this crop; the nearby Cancel discards only the current crop adjustment.

  4. Rotate and Mirror

    Rotate turns the photo clockwise by 90° per tap. Mirror flips it horizontally. These are separate from the horizontal perspective adjustment.

  5. Keystone

    Tap Keystone and adjust horizontal perspective with the slider. Use the review-style grid to judge alignment; tap the numeric value to reset to zero. The bottom Done accepts the adjustment, while its nearby Cancel restores the state before entering Keystone.

  6. Filters

    Open Filters in the photo editor and choose a preset. Adjust its intensity and compare with the original. Use the editor’s top Done to save before exporting or sharing; choosing a filter alone does not save the edit.

  7. Undo and Redo

    Finish the active tool before stepping through edit history. While Crop or Keystone is active, either history button first cancels that uncommitted tool adjustment and closes the tool.

  8. Save or leave

    The top Done saves the full edit; wait for Saving to finish. Top Cancel exits without keeping unsaved changes and asks for confirmation when needed. Accepting a tool adjustment is not the same as saving the full edit.

  9. Use or remove the edit

    A saved edit appears under Photo Version → Edited. Select Edited before Share to share that version; saving an edit does not itself save a copy to Photos. To remove a saved edit, use the viewer menu → Revert Manual Edits. Original and Auto Corrected remain available.

Keep a useful Library

Open Library from the bottom-left camera button. Use Photos and Albums at the bottom to switch collections.

  1. Find a photo. Open the top-right funnel menu to choose Grid or Masonry, filter All / Corrected / Originals, or browse Favorites, By Time and By Location.
  2. Group a project. In a photo’s top-right menu, choose Add to Album. For several photos, tap Select at the top right of Library, select the thumbnails, then choose an available batch action.

Save or share your result

A photo in Plumb is not automatically a copy in the iPhone Photos app.

  1. Save one photo. In the viewer’s top-right menu, choose Save Original to Photos or Save Corrected to Photos. Allow Photos access when prompted.
  2. Share the version you want. Choose the intended Photo Version first, then tap Share. To share your manual adjustments, choose Edited before opening the system share sheet.

Set it up your way

Tap the gear at the bottom right of the camera. These settings are worth checking once.

  1. Framing. Choose 4:3, 16:9 or 1:1 under Aspect Ratio. Turn Grid on for a composition guide.
  2. Photos. Save Captures controls automatic saving: Off, Original, Corrected or Both. Save Albums separately chooses Plumb, Photos or Both as the album destination.
  3. Location and language. Record Location adds location when available. App Language changes the app’s language; the language switch at the top of this page changes only this guide.

A little more help

There is no corrected version yet.

Wait for processing to finish. If only the original is available, open its top-right menu and choose Correct Photo when enabled. The original stays available while correction is being prepared.

My photo is in Plumb, but not in Photos.

Check Settings → Photos → Save Captures, then try a manual save from the viewer. Read any permission or save-limit message shown in the app; local viewing and saving to Photos are different actions.

Where is iCloud sync?

Pro includes optional iCloud Sync, off by default. Open Settings → iCloud. When enabled, it stores supported photos, edits, locations and albums in your private CloudKit database managed by Apple and uses your iCloud storage. Turning it off or losing Pro does not delete previously synced records. Sync Now requests a sync. Follow the status shown there; turning sync on is not confirmation that a particular photo has finished syncing. Perspective correction itself runs on the iPhone.
