Many digital cameras have a mode selection dial where you can select a shooting mode of P, Tv, Av or M. When you select one of these modes, it tells the camera to make specific settings as far as shutter speed and aperture. The differences between the four basic modes are:

· Program (P): Use this mode when you want the camera to select both the shutter speed and aperture for you. The camera will make a "best guess" selection on shutter speed and aperture based on the information coming into the camera.

· Shutter Priority (Tv): Use this mode when you are trying to control motion. You select the shutter speed and the camera selects the aperture.

· Aperture Priority (Av): Use this mode when you want to control depth-of-field. You select the aperture and the camera selects the shutter speed.

· Manual (M): Use this mode when you want to control both motion and depth-of-field. You select both shutter speed and aperture.

Using these modes lets you flex your creative side from none in Program mode to the maximum in Manual mode and everything in-between.

Assignment:

1. Select a subject. Meter the subject using the Program mode first and note the shutter speed and aperture settings.

2. Now shoot the picture. Use other shutter speed and aperture settings when shooting in the three other modes. Study how each mode changed the way the image looks as far as how motion or depth-of-field was depicted.

Using this photo tip and assignment as a guide, in the future, ask yourself first which mode would be the best to use for a particular shot.
