On digital cameras there is usually a wheel at the top of the camera to select the mode on the camera.

Each camera uses different abbreviations, for example S and A on Nikon and Sony, Tv and Av on Canon and Pentax. A for Automatic, P for Program, S/Tv for Shutter Priority, M for Manual, and Scene for the mode that sets the subject to be photographed.
1. Auto Mode
In this mode, the camera analyses the subject and adjusts the camera settings. You can point and shoot immediately without having to change the camera settings. However, the photos are usually less than optimal. Auto mode is good when you're in a hurry and don't have time to set up the camera.
The new camera model comes with Intelligent Auto, which is an auto mode with additional features such as Face Detection, i-Contrast (Canon) or D-Lighting (Nikon). These features are very useful for improving your photos even when using Auto mode.
2. Scene Mode
In this mode we select the object to be photographed.
Several types of scene modes:
a. Portrait
The camera automatically makes the subject's face more prominent by narrowing the depth of field so that the background becomes blurry.
b. Landscapes
The camera sets the depth of field to be wide so that the object looks sharp. This mode highlights green and blue.
c. Macros (Close up)
If you want to take photos from close range, you can use this mode to maximize your photo results.
d. Sports
This mode is used when photographing fast moving objects. The focus on the camera will move following the movement of the object.
e. Night portrait
You can use this mode when shooting at night. The flash on the camera will turn on automatically.
f. Sunset/sunrise
Used when you want to photograph the sunrise and sunset.
g. Fireworks
This mode is used to photograph fireworks with a very slow shutter speed.
h. Beach / snow
The camera will make settings so that the photo is not too bright because it measures the settings using a white background.
