Mode dial
Mode dial is used to change camera's mode. Most digital cameras, especially dSLR and SLR-like cameras, employ a mode dial. On point-and-shoot cameras, mode dials generally offer a range of scene types. On dSLR cameras and SLR-like cameras, mode dials usually offer access to manual settings.
Manual modes include:
- P: Program mode offers partial control over shutter speed and aperture.
- Tv or S: Shutter priority controls the shutter speed, and aperture is calculated by the camera.
- Av or A: Aperture priority controls the aperture, and the shutter is calculated by the camera.
- M: Manual mode controls shutter speed and aperture independently.
Automatic modes include:
- Auto mode gives complete control to the camera's metering system.
- Action or sport mode increases ISO and widens the aperture for a short shutter speed.
- Landscape mode shrinks the aperture for greater depth of field.
- Portrait mode widens the aperture for softer features and narrower depth of field.
- Night portrait mode takes a flash shot of the nearby subject with an extended shutter exposer to capture lights in the background.
