The camera on your MacBook Pro can be used for a variety of different reasons. It is typically not used in the same way as a common camera on your phone or other devices. It would look pretty hilarious if you help up your computer for a family photo, wouldn’t it?! I suppose it would work for this, but most people use the built-in camera on their computer for other reasons than taking photos.

1. Video Calls & Chats

One of the most common uses for the built-in camera on your MacBook Pro is for video calls and chats. Well known apps such as Facetime and Skype and utilize the camera to record your image in real-time and show it to whoever you are calling with. Since the camera on your laptop is located above your screen, it is easy to adjust the angle to center it on your face or body to make these calls happen. These cameras work really well for these calls and chats.

2. Photo Booth

Although it’s not very common to use your laptop in a similar fashion as a regular camera, that doesn’t mean it can’t be done. With the Photo Booth app on your MacBook Pro, you can take fun and creative photos easily from your computer. The app operates similar to an old-school photo booth where you hit a button, hear a countdown, and then a photo or two are taken. Photo Booth can be really fun and I’ve had a bunch of laughs using the program.

3. Live Streams

Another thing you can use your built-in camera for is live streaming. You won’t have the best high-quality using your computer’s camera but you can easily live stream any talking or informative content if you have a YouTube channel or are currently a video blogger or interested in learning how to do so. Using the camera on your MacBook is an easy way to learn the basics of how to live-stream and video blog and a lot of people use it for this reason.

How to Turn Your Camera On

In order to operate your camera and utilize it for any of the above purposes or whatever other reason you might want it for, you need to turn it on. It’s actually really easy to do and pretty self-explanatory so once you learn how to turn it on, you’ll probably never forget how.

The first step to turning on your camera is to open whatever app you want to use your camera for. This could be any of the apps mentioned above including Facetime, Skype, or Photo Booth. There are other apps that use the camera feature and those can work for turning your camera on too.

When some of these apps are opened, such as Photo Booth, the camera will come on automatically. For the other apps, like Facetime and Skype, you might need to click on the video icon to turn the camera on. You’ll know that your camera is on because there will be a small green light that comes on right next to the camera lens. You’ll also see the image that the camera is capturing displayed within the window of the app you are using.

If Your Camera Doesn’t Turn On

Sometimes you might open up one of these apps and your camera will not turn on. There are a few troubleshooting tips you can use to try and fix the problem.

First, make sure that you only have one app that uses the camera open at a time. If you have two apps open and both are trying to use the camera, chances are only one will have access and the other won’t work. Close any programs that might be trying to use your camera except the one you want to use.

You can also try restarting your computer and then opening up an app that uses the camera. This usually fixes the problem if you don’t know why your camera is not turning on. If the restart doesn’t work, you might need to update your operating system or the photo/video app you are trying to use.
