You’ve seen it. That square bump on the back of the iPad Pro. It looks like it was ripped straight off an iPhone 11 or 12, but it feels a bit weird on a giant slab of aluminum. Why does an iPad with two cameras even exist? Most people just use their phone for photos. Honestly, if you’re at a wedding or a concert holding up a 12.9-inch screen to take a video, you’re basically a public menace.
But Apple didn't just slap a second lens on there to hike the price. The dual-camera setup—specifically on the iPad Pro models starting from 2020—was a calculated move. It’s about more than just "pretty pictures." It’s about how the device "sees" the world. If you think that extra lens is just for zoomed-in shots of your cat, you're missing the entire point of why this hardware exists.
The Reality of the Dual Camera Setup
Let’s get the specs out of the way first. On the iPad Pro models that feature this, you’re looking at a 12MP Wide camera and a 10MP Ultra Wide camera. It's not a telephoto lens. You can't zoom into the moon with it. Instead, that Ultra Wide lens is there to pull back. It gives you a 125-degree field of view.
It’s great for tight spaces. Imagine you're an interior designer or a real estate agent. You can’t exactly back through a wall to get the whole kitchen in the frame. That’s where the Ultra Wide shines. But the real magic isn't even the glass. It's the little black circle next to it: the LiDAR scanner.
LiDAR stands for Light Detection and Ranging. It’s the same tech used in self-driving cars to map surroundings. When you combine the iPad with two cameras and a LiDAR sensor, you aren't just taking a 2D image. You are capturing 3D data. The iPad pulses lasers (don't worry, they're invisible) to measure exactly how far away every object in the room is. This happens at the speed of light. It builds a depth map of your environment instantly.

Standard cameras struggle with depth. They guess. LiDAR knows. This is why AR (Augmented Reality) on an iPad Pro is miles ahead of a standard iPad Air or the base model. If you place a virtual sofa in your living room using an AR app, it doesn't "float" awkwardly over your coffee table. It sits behind the table because the iPad knows the table is closer to you.
Why the iPad Pro Has This Hardware (And the Air Doesn't)
You might wonder why the M2 or M3 iPad Air doesn't have the dual-camera vibe. Apple is very deliberate about gatekeeping features. The iPad with two cameras is a "Pro" badge.
If you're a casual user, you don't need it. You really don't. Most of us just need a decent front-facing camera for Zoom calls. That’s why Apple finally moved the front camera to the landscape edge on the newer models—a move that took way too long, frankly. But the rear dual-camera system is for a specific niche.
- Architects and Contractors: They use apps like Canvas or Polycam. They walk through a room, "paint" the walls with the camera, and five minutes later, they have a fully textured 3D CAD model. Doing that with a single camera is a nightmare. It’s glitchy. With the dual-camera and LiDAR combo, it’s precise.
- Video Creators: Having a Wide and Ultra Wide lens on a device that is also a powerful editing station (thanks to the M-series chips) simplifies the workflow. You can film a b-roll shot in 4K, drop it straight into LumaFusion or Final Cut Pro for iPad, and have a finished social media clip without ever touching a computer or an SD card.
- Education: Think about anatomy apps. Students can place a life-sized, anatomically correct human heart on a desk. They can walk around it. The dual-camera system keeps that heart anchored to the physical world so perfectly that it feels like it's actually there.
The "Dumb" Way to Use Your iPad Cameras
Look, we have to talk about the elephant in the room. Taking photos in public with an iPad. Just stop.
The sensors in the iPad with two cameras are good, but they are rarely as good as the latest iPhone. The iPhone has better image signal processing and usually a larger sensor. The iPad’s cameras are essentially there for utility. Scanning documents? Yes. The dual-camera system helps eliminate shadows and ensures the edges are crisp. Quick reference shots for a project? Perfect.
But if you’re at the Grand Canyon, put the iPad in your backpack. Use your phone. The iPad is a workstation. Treat its cameras like tools, not like a point-and-shoot.
What Most People Get Wrong About LiDAR and Depth
There’s a common misconception that the second camera is doing the heavy lifting for "Portrait Mode." It’s actually more complex. While the two lenses help with depth perception, the iPad Pro relies heavily on the LiDAR sensor to separate the subject from the background.
On an iPhone, the software does a lot of "guessing" where the hair ends and the background begins. This is why you sometimes get that weird blur around your ears. The iPad with two cameras uses the LiDAR to create a "mask." It knows exactly where you stop and the wall starts. This makes for much cleaner cutouts in apps like Procreate Dreams or when using the "Remove Background" feature in iPadOS.
It’s also a massive accessibility win. For users with visual impairments, the dual-camera and LiDAR system powers "Door Detection" in the Magnifier app. It can tell a user how far away a door is, if it's open or closed, and even read the room number or sign next to it. That's not just a "neat feature." It's life-changing tech hidden in a camera bump.

The hardware is there. The M4 or M2 chips are screaming fast. But the software is... well, it's iPadOS.
You have this incredible iPad with two cameras, but Apple’s own Camera app is shockingly basic. You can’t control shutter speed manually. You can’t easily swap between frame rates without diving into the Settings menu. It feels like driving a Ferrari with a speed limiter set to 35 mph.
Thankfully, third-party developers have stepped in. If you actually want to use those two cameras for professional work, you need to ditch the stock app.
- Halide: This is the gold standard. It lets you see the actual depth map the LiDAR is creating. It gives you manual focus, which is crucial when the autofocus gets confused by glass or shiny surfaces.
- Filmic Pro: If you’re serious about video, this is the only way to go. It lets you lock the lenses so the iPad doesn't try to "auto-switch" between the Wide and Ultra Wide when the light gets low.
The Evolution of the Camera Bump
If you look at the history of the iPad, the camera was always an afterthought. The first iPad didn't even have one. Then we got those grainy, 0.7MP sensors that looked like they were covered in Vaseline.

The shift to an iPad with two cameras happened because Apple realized the iPad isn't a "big iPhone." It’s a spatial computer. It’s meant to interact with the room. That’s why the cameras are positioned where they are.
Interestingly, in the latest M4 iPad Pro models, Apple actually removed the Ultra Wide camera for some users, opting for a single "Pro" Wide camera and an improved LiDAR/Flash combo. Why? Because they realized most people weren't using the Ultra Wide for photos—they were using it for document scanning and AR. They optimized the hardware to be better at those specific tasks rather than trying to mimic an iPhone. It's a rare moment of Apple simplifying a "Pro" device by removing a lens, but it actually makes the remaining camera better for its intended purpose.
Actionable Steps for iPad Owners
If you have an iPad with two cameras, you’re sitting on a lot of untapped power. Here is how to actually use it:
- Stop taking 2D photos of your house: Download an app like Canvas (by Occipital). Use your camera to walk through your home. It will generate a 3D model that you can export to SketchUp or just use to measure furniture. It’s incredibly accurate.
- Scan documents properly: Don't just take a photo. Use the Files app or Notes app. The dual-lens system and the flash work together to flatten the image and remove the "fold" shadows that usually ruin scans.
- Try "Stage Manager" with an external monitor: If you're doing a video call, use your iPad’s rear cameras as your webcam. They are significantly better than almost any built-in laptop camera on the market. You'll need a mount, but the quality jump is massive.
- Check your depth: If you're a hobbyist, download Polycam. Use the LiDAR mode to scan a piece of fruit, a shoe, or a statue. You can turn it into a 3D object and drop it into a digital space or even 3D print it.
The iPad with two cameras isn't about being a better photographer. It’s about being a better "recorder" of the physical world. It’s a tool for capturing dimensions, depths, and spaces. Once you stop thinking of it as a camera and start thinking of it as a spatial sensor, the whole device makes a lot more sense.
