Liquid Glass – the tech world’s abuzz with this new term from Apple’s design playbook following their reveal of the new slew of operating systems at WWDC 2025. What is liquid glass? Well, it’s a multi-tier strategy on Apple’s part to redefine interfaces, moving away from the minimalist interfaces to introduce gorgeously refractive glass-like interfaces instead. These glass elements interact with screen elements by bending light like real glass would. Think of holding a magnifying glass to a newspaper to watch the text around the edges warp while the center stays clear. There’s speculation that this move towards glass-based interfaces was a conscious effort to further Apple’s spatial interface goals… but to be honest, we were in love with Liquid Glass back as early as 2021. What do I mean? Well, I’m talking about the NightWatch, an Apple Watch dock from 4 years ago that did exactly what Liquid Glass did, amplify the watch’s screen into a gorgeous liquid orb while your watch was charging! Designer: NightWatch Click Here to Buy Now The NightWatch, as its name so succinctly implies, is a dock for your watch while it charges overnight. Shaped like a massive orb, this dock turns your watch’s night-time charging face into a massive, magnified alarm clock that’s easier to see. Moreover, the dock amplifies the watch’s audio too (through clever design details), transforming your Watch into a makeshift alarm clock that works remarkably well. There’s no hidden components, no inner trickery – the entire NightWatch is a cleverly designed, solid piece of lucite that does three things remarkably well. First, it docks the Apple Watch and charger inside it, magnifying the watch screen so the numbers are clearly legible even from a couple of feet away. Secondly, channels located strategically under the Watch’s speaker units amplify the sound (sort of like how your voice is louder when you cup your hands around your mouth) so your alarm rings louder. Thirdly (and this might be the best feature yet), the lucite orb is touch-sensitive. Which means a mere tap on the surface causes your Watch screen to wake so you can see the time! The dock may have been designed in 2021, but its design philosophies align with Apple’s Liquid Glass push brilliantly. Liquid Glass is all about mimicking real-world materials, bringing physicality to the digital world while still maintaining a pristine aesthetic that boosts focus and highlights important elements. That’s exactly what the NightWatch does too – it takes the Watch’s flat digital interface and brings real-world physicality to it through the refraction and magnification of the clear lucite. It also helps easily highlight important elements by enlarging your watch face for clearer timekeeping. The NightWatch is compatible with all Apple Watch series (as long as your watch doesn’t have a case on it).

DJI Osmo Action 4. Adrian Kingsley-Hughes/ZDNETMultiple DJI Osmo Action 4 packages are on sale at Amazon. Both the Essential and Standard Combos have been discounted to $249, while the Adventure Combo has dropped to $349.DJI might not be the first name on people's lips when it comes to action cameras, but the company that's better known for its drones also has a really solid line of action cameras. And its latest device, the Osmo Action 4 camera, has some very impressive tricks up its sleeve.Also: One of the most versatile cameras I've used is not from Sony or Canon and it's on saleSo, what sets this action camera apart from the competition? Let's take a look. details View at Amazon First off, this is not just an action camera -- it's a pro-grade action camera.From a hardware point of view, the Osmo Action 4 features a 1/1.3-inch image sensor that can record 4K at up to 120 frames per second (fps). This sensor is combined with a wide-angle f/2.8 aperture lens that provides an ultra-wide field of view of up to 155°. And that's wide. Build quality and fit and finish are second to none. Adrian Kingsley-Hughes/ZDNETFor when the going gets rough, the Osmo Action 4 offers 360° HorizonSteady stabilization modes, including RockSteady 3.0/3.0+ for first-person video footage and HorizonBalancing/HorizonSteady modes for horizontal shots. That's pro-grade hardware right there.Also: This new AI video editor is an all-in-one production service for filmmakers - how to try itThe Osmo Action 4 also features a 10-bit D-Log M color mode. This mode allows the sensor to record over one billion colors and offers a wider dynamic range, giving you a video that is more vivid and that offers greater detail in the highlights and shadows. This mode, combined with an advanced color temperature sensor, means that the colors have a true-to-life feel regardless of whether you're shooting outdoors, indoors, or even underwater. The DJI Osmo Action 4 ready for action. Adrian Kingsley-Hughes/ZDNETI've added some video output from the Osmo Action 4 below. There are examples in both 1080p and 4K. To test the stabilization, I attached the camera to the truck and took it on some roads, some of which are pretty rough. The Osmo Action 4 had no problem with that terrain. I also popped the camera into the sea, just because. And again, no problem.I've also captured a few time-lapses with the camera -- not because I like clouds (well, actually, I do like clouds), but pointing a camera at a sky can be a good test of how it handles changing light. Also: I recommend this action camera to beginners and professional creators. Here's whyTimelapses with action cameras can suffer from unsightly exposure changes that cause the image to pulse, a condition known as exposure pumping. This issue can also cause the white balance to change noticeably in a video, but the Osmo Action 4 handled this test well.All the footage I've shot is what I've come to expect from a DJI camera, whether it's from an action camera or drone -- crisp, clear, vivid, and also nice and stable.The Osmo Action 4 is packed with various electronic image-stabilization (EIS) tech to ensure that your footage is smooth and on the horizon. It's worth noting the limitations of EIS -- it's not supported in slow-motion and timelapse modes, and the HorizonSteady and HorizonBalancing features are only available for video recorded at 1080p (16:9) or 2.7K (16:9) with a frame rate of 60fps or below. On the durability front, I've no concerns. I've subjected the Osmo Action 4 to a hard few days of testing, and it's not let me down or complained once. It takes impacts like a champ, and being underwater or in dirt and sand is no problem at all. Also: I'm a full-time Canon photographer, but this Nikon camera made me wonder if I'm missing outYou might think that this heavy-duty testing would be hard on the camera's tiny batteries, but you'd be wrong. Remember I said the Osmo Action 4 offered hours of battery life? Well, I wasn't kidding.  The Osmo Action 4's ultra-long life batteries are incredible.  Adrian Kingsley-Hughes/ZDNETDJI says that a single battery can deliver up to 160 minutes of 1080p/24fps video recording (at room temperature, with RockSteady on, Wi-Fi off, and screen off). That's over two and a half hours of recording time. In the real world, I was blown away by how much a single battery can deliver. I shot video and timelapse, messed around with a load of camera settings, and then transferred that footage to my iPhone, and still had 16% battery left.No action camera has delivered so much for me on one battery. The two extra batteries and the multifunction case that come as part of the Adventure Combo are worth the extra $100. Adrian Kingsley-Hughes/ZDNETAnd when you're ready to recharge, a 30W USB-C charger can take a battery from zero to 80% in 18 minutes. That's also impressive.What's more, the batteries are resistant to cold, offering up to 150 minutes of 1080p/24fps recording in temperatures as low as -20°C (-4°F). This resistance also blows the competition away.Even taking into account all these strong points, the Osmo Action 4 offers even more.The camera has 2x digital zoom for better composition, Voice Prompts that let you know what the camera is doing without looking, and Voice Control that lets you operate the device without touching the screen or using the app. The Osmo Action 4 also digitally hides the selfie stick from a variety of different shots, and you can even connect the DJI Mic to the camera via the USB-C port for better audio capture.Also: Yes, an Android tablet finally made me reconsider my iPad Pro loyaltyAs for price, the Osmo Action 4 Standard Combo bundle comes in at $399, while the Osmo Action 4 Adventure Combo, which comes with two extra Osmo Action Extreme batteries, an additional mini Osmo Action quick-release adapter mount, a battery case that acts as a power bank, and a 1.5-meter selfie stick, is $499.I'm in love with the Osmo Action 4. It's hands down the best, most versatile, most powerful action camera on the market today, offering pro-grade features at a price that definitely isn't pro-grade.  Everything included in the Action Combo bundle.
