Computational photography is responsible for most of the amazing strides our smartphone cameras have taken in the last decade. Here’s how it works, and how it makes our photos so much better. The Magic of Computational Photography Computational photography uses digital software to enhance the photos taken by a camera. It’s most prominently used in smartphones. In fact, computational photography does the heavy lifting to create the great-looking images you see in your smartphone photo gallery. The rapid improvement in smartphone cameras over the last few years can largely be attributed to improving software, rather than changes to the physical camera sensor. Some smartphone manufacturers, like Apple and Google, continuously improve the photo-taking capabilities of their devices year after year without ever drastically changing the physical camera sensors. Why Does Computational Photography Matter? How a camera digitally captures a photo can be roughly divided into two … [Read more...] about What Is Computational Photography?

You might not realize it, but every time you purchase a new desktop CPU, you also get a ticket for a giveaway called the “silicon lottery.” Two CPUs of the same model can perform differently when pushed to their limits thanks to something called “CPU binning.” What Is Binning? Binning is a sorting process in which top-performing chips are sorted from lower-performing chips. It can be used for CPUs, GPUs (graphics cards), and RAM. Say you want to manufacture and sell two different models of CPU: one that’s fast and expensive, and another that’s slower at a bargain price Do you design two different models of CPU and manufacture them separately? Why bother when you could just use “binning?” The manufacturing process is never perfect, especially given the incredible precision necessary to produce CPUs. When you’re manufacturing those speedy, expensive CPUs, you’ll end up with some that just can’t run at the top-end speeds. You can then tweak these to run at slower speeds and … [Read more...] about What Is “Binning” for Computer Components?
When it comes to smartphone cameras, it’s not all about the hardware anymore. Modern smartphones automatically use “computational photography” techniques to improve every single photo you take. Using Software to Improve Your Smartphone Camera Computational photography is a broad term for loads of different techniques that use software to enhance or extend the capabilities of a digital camera . Crucially, computational photography starts with a photo and ends with something that still looks like a photo (even if it could never be taken with a regular camera.) How Traditional Photography Works Before going any deeper, let’s quickly go over what happens when you take a photo with an old film camera. Something like the SLR you (or your parents) used back in the ’80s. When you click the shutter-release button, the shutter opens for a fraction of a second and lets light hit the film. All the light is focused by a physical lens that determines how everything in the photo will … [Read more...] about How Computational Photography Improves Smartphone Photos
All Windows 10 PCs have “Game Mode” enabled by default. Microsoft once touted this feature, but it’s now faded into the background. Bizarrely, some people report that disabling Game Mode boosts the performance of certain PC games! What Does “Game Mode” Do on Windows 10? First introduced in Windows 10’s Creators Update , which was released back in April 2017, “ Game Mode ” promises to boost the performance of many PC games. Here’s the official description: Microsoft says that Game Mode “helps achieve a more stable frame rate depending on the specific game and system.” Technically, it works by detecting games and giving them priority access to your computer’s resources. The game you’re focused on playing gets more CPU and GPU resources, while other applications and background processes get fewer resources. This only works if Windows 10 detects that you’re playing a game. Microsoft’s limited explanation of Game Mode also says that, in Game Mode, Windows Update won’t … [Read more...] about Did You Know? Windows 10 PCs Have “Game Mode” on by Default
Thanks to Developer Mode on the Xbox Series X and S, you can install emulators like RetroArch . Turn your Xbox Series X or S into a retro gaming powerhouse and emulate the PS2, GameCube, Dreamcast, and more, all without impacting your ability to play retail games. First, Activate Developer Mode The first thing you have to do is activate Developer Mode on your Xbox . To do so, you’ll need a paid Microsoft Partner developer account. This requires a one-time fee of $19 (pricing is different in other regions). Once you’ve activated your account, you can add your Xbox as a developer console. RELATED: How to Put Your Xbox Series X or S into Developer Mode With a valid developer account, you can download the Xbox Dev Mode app, activate your console in Partner Center, and then reboot in Developer Mode. From there, it’s just a matter of configuring your network connection, and then accessing the Xbox Developer Mode web interface via a browser. For this guide, we’ll … [Read more...] about How to Install the RetroArch Emulator on Xbox Series X or S
