Why your webcam looks bad (it's usually not the webcam)
A webcam looks bad for one of three reasons, in this order: not enough light on your face, light coming from behind you, or the camera sitting below your eyes. The camera itself is almost never the first thing to fix. A £30 webcam with a lamp in front of you beats a £200 one in a dark room, and you can test which problem you have in two minutes without buying anything.
The two-minute test
Open your camera app and look at yourself. Now turn on every light in the room and point a desk lamp at your face from in front. If the picture is suddenly much better, your problem was light, and no camera would have fixed it. If it’s still bad, raise the camera to eye level. If it’s still bad after that, now you can talk about the camera.
Light: the usual culprit
Webcam sensors are tiny. In a dim room they boost their sensitivity, which is where grain, smeary motion and muddy colour come from. The fix is more light on your face, from the front, a little above your eyes. A desk lamp bounced off a white wall works. A window in front of you works brilliantly in the daytime and not at all at night, which is why evening calls look worse.
The opposite problem is light behind you: a window or a bright lamp in the background. The camera decides the scene is bright, darkens everything, and you become a shadow. Turn around, or close the blind.
Position: where the camera sits
A laptop on a desk puts the camera below your chin, looking up. Nobody looks good from there. Raise it to eye level and sit about an arm’s length back. If you use an external webcam, clip it to the top of your monitor rather than leaving it on the desk.
The room
A plain wall a couple of metres behind you is better than a cluttered shelf right behind your head, and a room with a bit of depth looks more natural than one where your back is against the wall. This matters less than light and position but it’s free, so do it.
Only then, the camera
Once the light is in front of you and the camera is at eye level, a better camera does make a difference: sharper, better colour, less smearing when you move. But it’s the fourth thing, not the first, and most advice online puts it first because the person giving the advice is paid when you buy one.
How Gearit works this out for you
Gearit gives your whole setup one score and breaks it into five parts: Video, Audio, Lighting, Room & Position and Workflow. A setup scoring 44 overall with Lighting at 29 and Video at 34 has a lighting problem, and the app says so before suggesting anything to buy. Its plan then lists what to change in the order that helps most, cheapest first, with real prices. The scanning happens on your iPhone and your photos and report stay there; the lookup only ever sends the words you typed.
Questions people ask
Why is my webcam so grainy?
Not enough light. A small camera sensor in a dim room turns up its sensitivity to compensate, and grain is what that looks like. Put a lamp in front of you, slightly above eye level, and the grain goes before you change anything else.
Why is my face dark on video calls?
There's a window or a light behind you. The camera exposes for the bright background and leaves you as a silhouette. Turn to face the window, or close the blind and light yourself from the front.
Will a better webcam fix it?
Only if light and position are already right. A better camera in a dark room is a sharper picture of a dark room. Gearit scores each part of a setup separately, so you can see whether Lighting or Video is actually the weak one before spending.
Where should the webcam be?
At eye level or just above, and about an arm's length away. A laptop camera on a desk looks up your nose. Put the laptop on a stack of books, or clip the webcam to a monitor at the right height.
What's the cheapest fix?
Usually a lamp you already own, moved in front of you. After that, a stack of books under the laptop. Both cost nothing. Gearit's plan lists fixes cheapest first for exactly this reason.
