Two-Point Perspective Camera uses your iPhone’s gyroscope to automatically correct vertical perspective in real time. 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. Key Features -Gyroscope Auto Correction — automatically compensates for camera tilt -Real-Time Perspective Preview — see the corrected composition before shooting -Manual Correction — fine-tune vertical perspective with precise adjustment -Two-Point Perspective — keep architectural verticals parallel -High Resolution — capture detailed architectural photographs -Multiple Aspect Ratios — compose for different photographic formats -Grid & Level — precise framing for architecture and interiors

About

Hidden Layer

Features

The photos we take often hide a dozen or so layers! Let's go see what's inside. This app lets you view every layer in a photo, and it also has a few useful or fun photo tools! View Layers Pick a photo and you'll see all kinds of layers inside it — maybe a depth map, a glasses mask, and more. Every layer comes with a detailed explanation. You'll discover a lot! For example, I found out that with ProRAW, what I usually see in my photo library is just the JPG preview layer inside… Of course, you can export layers too. For example, export the Low-Processing Rendering of a ProRAW main photo — a special rendering you've probably never seen. It's closer to the raw data and great for editing! You can also export the depth map and use it in Photoshop for more accurate background blur. Photo Tools Oh, and using these hidden layers, we can also process photos. For example, add a depth map to a regular photo and it becomes a Portrait mode photo, so you can refocus and add background blur right in the Photos app! There's also Remove Sharpening and Natural Key Photo — really useful if you prefer less sharpening, or want your Live Photo key photo to keep its colors. This is just the beginning. If you have a good idea, let me know!
