Some higher-resolution cameras have what's called AI autofocus, which combines autofocus with digital zoom to center the frame around your face as you move around within the camera's field of view. This is obviously preferable, since you don't have to worry about being just the right distance away. More expensive webcams typically have autofocus, which means their lenses will adjust to make sure you're clear at any distance from the camera. They work fine if you're just sitting directly in front of the camera a few feet away, but it's easy to get out of that sweet spot of focus and become blurry (especially if you want to show something up close). This means their lenses don't move to adjust the picture, and are simply set to capture you within a wide enough range of distance that you'll show up clearly. A webcam's field of view will typically range between 65 and 90 degrees, with 78 degrees as a common middle ground. If you want to record an entire conference room, you want a wide field of view. If you want to capture only your face and cut out your messy bedroom, you want a narrow field of view (or a high-enough resolution that you can crop the frame). The lens also determines the camera's field of view, and that's important when considering framing. Webcams don't often advertise their aperture sizes, but they generally range from f/2.0 to f/2.8. This is known as the aperture size, and is measured as f/(number) for most types of cameras, with the lower the number the wider the aperture and the more light that gets in. The lens determines how much light reaches the camera sensor, which affects how you'll look if you don't have good lighting. The lens on a webcam is just as important as the sensor, and generally bigger is better. A 60fps webcam will give you a much more realistic and natural video feed than a 30fps webcam will, so be sure to pay close attention to the specs before buying. 1080p is a fairly standard resolution for a decent webcam, but if you really want to up your picture quality (or be able to crop your frame and keep it sharp), you want a 4K webcam.įrame rate also affects how smooth your video looks. A webcam can only get as sharp as its sensor can resolve pixels. Here's what you need to know when shopping for a webcam, along with some models worth considering. It's a worthwhile investment if you're planning to spend a lot of time on calls, recording vlogs, or doing anything else with video. A good dedicated webcam will solve those problems, and give you the flexibility to aim it wherever you want without wrestling with your laptop. Small lenses, skewed colors, awkward exposure, and grainy indoor video are just some of the problems with might experience with cheap, built-in webcams. It probably isn't a very good one, though. If you have a laptop, you already have a webcam. You still want to look your best in a video meeting, and that goes beyond showering and getting dressed. Everyone is teleconferencing, and many companies are completely rethinking their stances on working from home.
