THE PRINCIPLE

Architecture is drawn with intention.
Photograph it the same way.

A small tilt of an iPhone can make parallel lines collapse inward. Plumb records the camera geometry at the instant of capture, then uses that evidence to form an upright image—without hiding the source frame.

TILT / DISTORTION / MANUAL CORRECTIONTHE PROBLEM

The familiar frustration

Less time adjusting perspective. More time observing architecture.

Point a camera upward and the building starts to fall away. Vertical lines converge, façades lean, and careful compositions lose their balance. For architects and architectural photographers, the image no longer reflects the building they designed—or the one standing in front of them.

01

Capture

Plumb uses shutter-time camera and motion evidence to create a natural, upright architectural photograph.

Live correction preview

Up to 48MP capture
Choose high-resolution capture on supported devices and lenses. Actual output varies with capture conditions and crop.

02

Refine

Fine-tune crop, rotation, mirror and horizontal perspective with the non-destructive editor. Keep the original intact.

Choose a filter preset in the photo editor and adjust its intensity. Refine colour and mood without replacing the original; save the edit before exporting or sharing.

03

Organize

Keep projects together with Current Shoot and albums. Browse your Library in Grid or Masonry.

One capture. Two honest versions.

Corrected, never overwritten.

Questions, squared away

FAQ

What does Plumb correct?+

Plumb corrects converging verticals and architectural perspective caused by tilting the phone, while preserving a natural-looking composition.

Does Plumb replace my original photo?+

No. Plumb retains the original camera resource and writes the corrected image as a separate version.

Are my photos uploaded?+

Perspective correction happens on your iPhone. Pro offers optional iCloud Sync, off by default, using your private CloudKit database managed by Apple. Plumb does not upload photos to a developer-operated server for correction.

Which iPhones are supported?+

Plumb supports iOS 18 and later, with iPhone 13 or newer recommended. Available capture features adapt to each device.

Free & Pro at launch

Free

Free access includes 10 successful saves of distinct corrected photos per device, per UTC calendar month. Failed saves and repeat saves of an already-counted photo do not use another allowance. At the limit, automatic correction turns off; original capture and existing local photos remain available.

Plumb Pro

Pro removes the corrected-photo save allowance and includes optional iCloud library sync. Choose monthly, annual or a one-time Lifetime purchase. Local price, currency and billing period are shown by Apple at purchase.

Sync is optional and off by default, uses your iCloud storage, and depends on Apple service availability.
