Focusing
Why should you avoid using auto focus when doing videography?
- If the photo-taker relies entirely on the automatic focus features in the camera, the resulting images will vary greatly. The auto-focus system in a camera simply sharpens the focus in a selected zone of the shot, irrespective of what is appearing there. So it needs to be used with care with an idea of how it works otherwise it'll focus incorrectly to what you want to shoot. For example: If two people are placed on either side of the frame, auto-focus may sharpen on an unimportant distant object in the center of the screen and leave the subjects soft-focused. The camera operator may want to focus on someone near the camera and a distant person at the same time, but auto-focus may sharpen on one or the other-or neither.
When is using the auto-focus acceptable?
- Many video cameras / cameras are fitted with an automatic focusing feature. The auto-focusing feature is a useful device for the occasions when the camera operator is preoccupied with following the action, is not sure where the subject is going to move to next, and might get the focusing wrong in the heat of the moment.
What are the 4 steps to properly set your focus manually when shooting a static subject (such as an interview)?
- 1- Turn the focus ring until your subject sharpens.
2- Switch your camera to live view mode (where the LCD is your viewfinder).
3- Tap the magnifier button to zoom in on your subject, and use the arrows on your camera to move the area of view. (Alternatively, move your camera to frame the subject, and re-compose.)
4- Fine-tune the focus until the subject is crystal-clear.
5- Tap the magnifier tool again to exit back to normal view before capturing your photo.
What does the term "rack focus" mean?
- A rack focus in film-making and television production is the practice of changing the focus of the lens during a shot. The term can refer to small or large changes of focus. If the focus is shallow, then the technique becomes more noticeable.
