Video formats can be confusing, and some might not work in your video player of choice, especially more obscure formats like MKV. It’s often easier or even necessary to convert them to something more usable, like MP4. Luckily, that conversion is easy to do.

Your camera uses a light meter to figure out the correct exposure settings for any scene. Like most “automatic” camera features, you do have some control over how it works. Let’s look at the different metering modes and when to use them.
Foreshadow, also known as L1 Terminal Fault, is another problem with speculative execution in Intel’s processors. It lets malicious software break into secure areas that even the Spectre and Meltdown flaws couldn’t crack.
A tar file, often called a tarball, is a collection of files wrapped up in one single file for easy storage. Rather than keep track of a whole folder of files, you only need to keep track of one. Tar files are often compressed after being created, giving it the .tar.gz file extension. Technically these are TGZ files, but nearly everyone calls both .tar and .tar.gz files simple “tar files.”
Setting up a web server and hosting your own website can be a fun and challenging learning experience. But if you’re looking to do this, you should check with your ISP first; it might be a violation of their terms of service.
Burst mode, where your camera keeps taking photos as long as you hold down the shutter button, is handy when you’re trying to take action, sports, wildlife, or any other kind of photos where the subject is moving quickly. There’s a knack to doing it right, so let’s dig in.
There are few things more annoying than tourists ruining an otherwise great photo. You can painstakingly edit them out by hand but, with a bit of forethought, you can get Photoshop to do it automatically.
Software engineers have always developed new ways of fitting a lot of data into a small space. It was true when our hard drives were tiny, and the advent of the internet has just made it more critical. File compression plays a big part in connecting us, letting us send less data down the line so we can have faster downloads and fit more connections onto busy networks.
DMG files are containers for apps in macOS. You open them, drag the app to your Applications folder, and then eject them, saving you the hassle of the dreaded “Install Wizard” of most Windows apps. So if all they are is a folder for an app, why do we use them instead of just downloading the app itself?
Modern digital cameras all write the photos and videos you take to removable storage cards, but which ones do you need? Let’s look at which SD cards—and CompactFlash, CFast, or XQD cards—are right for you.
A file with the .pdf file extension is a Portable Document Format (PDF) file. PDFs are typically used to distribute read-only documents that preserve the layout of a page. They’re commonly used for documents like user manuals, eBooks, application forms, and scanned documents, to name just a few.
As a photographer, you’ll want to control your camera remotely on occasion. For example, if you’re shooting landscapes by the sea and don’t want to get your feet wet, taking a group portrait you’re also in, playing around with self-portraits, or making a timelapse, remote control is essential. Let’s explore some of the different options.
An operating system is the primary software that manages all the hardware and other software on a computer. The operating system, also known as an “OS,” interfaces with the computer’s hardware and provides services that applications can use.
A file with the .mp3 file extension is one of the most commonly distributed audio files used today. The MP3 file was created by the Moving Pictures Experts Group (MPEG) and is abbreviated from MPEG-1 or MPEG-2 Audio Layer 3.
Photoshop is the biggest name in image editing, but it has a reputation as a complicated and difficult app to use. While it’s certainly feature packed, it’s nowhere near as difficult to get the hang of as it first appears. Let’s look at how to learn Photoshop without getting stuck in the weeds.
A 503 Service Unavailable Error happens when a web server is temporarily unable to handle a request that’s been made of it. Almost always, the error is on the website itself and there’s nothing you can do about it but try again later. Still, there are a few quick things you can try on your end.
Every camera has a burst mode: it’s where you hold down the shutter button and it keeps taking photos until you lift your finger. It’s great for shooting sports, wildlife, or any other situation where you’re trying to capture a fleeting moment. The thing is, you can’t use burst mode indefinitely; after a few moments, it slows down or stops entirely. Let’s find out why, and some of the things you can do to potentially increase the length of the bursts you can shoot.
Smoke alarms are cheap and pretty basic, but they can definitely be life savers. However, there might be some things you don’t know about smoke alarms that could make you rethink the ones you have now.
A file with the .MOBI file extension is used for storing eBooks. It was originally a Mobipocket Reader format but has since been adopted by several different readers as well. Amazon purchased Mobipocket in 2005, and later discontinued the MOBI format in 2011.
It’s common knowledge that water does bad things to electronics, but there are still a few things you may not know about how exactly water can damage electronic components and what you can do if you ever accidentally take your devices for a swim.
Sometimes the best way to troubleshoot and operating system, application, or service is to consult the log file(s) that app or service generates as it goes about its business. But what is a LOG file and how do you see what’s in it?
The viewfinder is the bit you look through on your camera when you’re taking a picture. There are two main kinds: optical viewfinders and electronic viewfinders, although live view screens are also used. Let’s look at the differences between them.
A refresh rate is the number of times your monitor updates with new images each second. For example, a 60 Hz refresh rate means the display updates 60 times per second. A higher refresh rate results in a smoother picture.
Photography and videography gear is expensive. Professional equipment starts at a few hundred dollars and goes up to hundreds of thousands. You might dream of shooting with a RED EPIC camera, but you probably don’t want to pony up the $19,000+ to own one. The thing is, there’s another option: rental.
Losing your hardware is bad enough, but what happens to your personal data? Could a thief with your phone, tablet, or laptop access your apps and files? It depends on the device you lost—unfortunately, most Windows PCs aren’t encrypted.
