As you tilt your phone up or down, the live view is continuously adjusted, allowing you to compose the corrected image before you press the shutter. No need to fix converging verticals afterward. For situations where sensor-based correction needs a little refinement, Manual Correction gives you precise control to fine-tune the perspective while you shoot.

About

Plumb

Read full description

Plumb is an iPhone camera with real-time perspective-correction preview, built for architecture, interiors and urban spaces. See corrected framing as you compose, then capture a separate corrected photo while keeping the original. LIVE PERSPECTIVE CORRECTION, BEFORE THE SHUTTER Turn on live correction preview to see how vertical lines and framing change as you move your phone. Compose building façades, interiors and street scenes before capture, then compare the original and corrected photos. Results depend on capture conditions; when a safe correction cannot be made, the original is preserved. RAW CAPTURE AND CORRECTED DNG EXPORT Capture 12MP/48MP RAW on supported devices and lenses. With correction on, export a corrected Linear DNG; with correction off, export the camera RAW for editing in compatible software. Editing inside Plumb applies to the non-RAW copy. FIND YOUR COLOR AS YOU SHOOT Swipe through live filters to preview the look before capture. Explore built-in styles including Classic, Morandi and Cool Tone, or create your own with curves, HSL and color grading. Try random color generation for inspiration, import compatible LUT files, and pin your favorites for easy access. EDIT FREELY. PRESERVE THE ORIGINAL. Crop, adjust perspective and color, or change filters after shooting. Edits are saved separately without overwriting the original photo or its capture information. Compare the original and edited result, view shooting parameters and edit details, and choose which original, corrected or edited version to save or share. ONE VISIT, ONE ALBUM Use Current Shoot to organize a session, create an album or add photos to an existing one. Browse your Library in a grid or masonry layout, and sort albums by recent updates or creation time. Exported photos automatically use filenames containing the capture time for easier archiving and sharing. LOCAL PROCESSING. YOUR CHOICE. Photos and correction processing stay on your iPhone. Your Library is stored locally by default; choose to save to Apple Photos, share, or enable iCloud Library sync with Plumb Pro. No Plumb account required, no ads and no cross-app tracking.
