A digital camera works basically the same way as a regular camera, and the features available on a particular camera are similar. That is, to take a picture with a digital camera, you point and shoot. Instead of film, though, the digital camera saves the image in its internal memory or on a special memory card. You can then copy the pictures from the camera’s memory or its card to your computer for editing, printing, emailing, and so on.
You can find a wide range of cameras. High-end cameras provide higher quality pictures and have extra features, such as swappable lenses, zoom features, and so on. With some cameras, you can even shoot and store a short video.
