A vlogging camera is an electronic optical device used to take an image. At their simplest, cameras are typically sealed boxes with just a tiny hole to allow light into the camera to take a picture. The camera body is called the camera sensor. Many cameras have different mechanisms to manipulate the way the light falls on the sensor to create the image. The lens is one component that allows light to pass through the camera and send an image to the digital computer, which stores the image.
