How to Focus a Digital Video Camera

Video Transcript

"After the end switches, there are another set of switch, which is called the focus switches. Now on every digital camera, there are three kinds of focuses. First is the auto-focus, where your camera focuses automatically. Secondly is the manual focus, where you can focus it manually using the focus ring. And thirdly is the infinity focus, where if you want to shoot a distance object which is not coming into focus, you can always shift it to infinity focus. So, in Panasonic PD173 also there are three focus switches. Now if you see here, it is switched on to manual. In manual focus, you have to focus it manually. If you push this switch up, it becomes auto focus. And if you pull this switch down, it becomes infinity focus. If you see more carefully after the focus switches, there's a small button underneath it. It is called the push auto. Push auto focus means that when you are shooting in a manual mode, and suddenly you have to focus up on a subject, you can only zoom in and push this button. It'll automatically focus a subject. And then when you release it, it will always remain in focus. After focus, in every digital camera, or any camera you use, there's another important thing, which is called the exposure, or the aperture. Every digital camera will have its own apertures settings. Here we can see it here. Now this is also called the iris button. There's a small toggle button. If you push it once, it becomes auto iris, where the camera automatically sets up its own exposure ratio. And if you toggle it again, it comes to the manual mode. Now once it comes to the manual mode, you'll see F-stop numbers on your LCD screen. After you toggle it on to the manual iris, you can see this dialing thing, which is just beside the button of the iris. Here is a positive sign and a negative sign. By switching this dial up and down, you can always set your aperture according to your needs."
