A digital camera has two camera modes, A and M. What's the difference?

The difference between a mode and m mode of digital camera;

Answer: In aperture priority mode, the user adjusts the aperture size and sensitivity, and then the camera automatically measures light to determine the shutter speed. This mode is easy to create different depth of field, and is often used when shooting outdoor portraits, animals and plants and products at macro.

M: In the full manual mode, the automatic metering of the camera doesn't work, and all parameters have to be manually adjusted by the user. The shooting mode with the highest degree of freedom can shoot in complex environment and get various special effects, but it requires users to have some experience and apply exposure instruments and other tools.

Other modes commonly used in digital cameras:

S: Shutter priority mode, the user adjusts the shutter speed and sensitivity, and then the camera automatically measures light to determine the aperture size. This mode is convenient to obtain different speed senses of objects, and is often used to shoot moving objects such as hot springs and cars and sports photography.

P: Program automatic mode, the user adjusts the sensitivity, and the aperture and shutter are determined by the camera automatic metering system. Less human intervention, suitable for quick snapshot.
