OrthoCam

Read full description

OrthoCam is a perspective-correction camera built for architecture and spatial photography. Shooting skyscrapers, interiors, bridges, and skylines, the last thing you want is slanted lines and perspective distortion. OrthoCam uses your device's motion sensors to align horizons and verticals in real time and automatically corrects wide-angle distortion — no post-processing needed. Level and straight, every shot. 【Key Features】 • Perspective Correction: Motion-sensing auto-aligns horizontal and vertical lines and fixes wide-angle distortion, so your shots come out level and straight. • Apple Log Workflow: Shoot in Apple Log to preserve maximum dynamic range and enjoy freer color grading in post. • 35 Pro-Grade LUTs: Built-in presets deliver professional looks straight out of camera; import your own LUTs too. • Multiple Aspect Ratios: Switch between common ratios freely for more flexible composition. • Pro Exposure: 13/24/50/100mm focal-length steps, independent exposure and spot metering for accurate results even in low light. • Grid Guides: Rule-of-thirds and golden-ratio overlays keep your composition on point. • Photos + Video: Correct perspective in stills; apply real-time LUT grading to video and export clips as Live Photos. • Fully On-Device: All processing happens locally — nothing is uploaded or collected, and your privacy never leaves the phone. From city skylines and historic eaves to interior spaces — level and straight, every shot. 【Pricing & Subscription】 Download free, with a full-featured 3-day free trial on first launch! Two subscription options to choose from: • Annual Membership (includes a 7-day free trial) Payment will be charged to your Apple Account upon confirmation. Subscriptions auto-renew; to cancel, turn off auto-renewal in your Apple Account's Subscriptions at least 24 hours before the current period ends. • Lifetime Membership — one-time purchase Unlock everything forever with a single purchase — no auto-renewal. Annual members can upgrade to Lifetime by paying the difference.

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. FREE ACCESS AND PLUMB PRO Try automatic perspective correction for free, with an allowance for saving corrected photos. Upgrade to Plumb Pro to remove that allowance and unlock iCloud Library sync. Choose a monthly or annual subscription, or a one-time lifetime purchase. Prices are shown before purchase. Monthly and annual subscriptions renew automatically and can be managed or canceled in your Apple Account settings. iCloud sync requires available iCloud storage.
