In some higher-level DCs and all DSLRs, you can see the options of M/A/S/P Mode and AUTO Mode. So what exactly do these words represent?

M (Manual Mode)- Full Manual Mode: aperture and shutter speed are set by the user

A (Aperture-priority Mode)- Aperture Priority Mode: The user sets the aperture value and the camera automatically calculates the appropriate shutter speed, which is mainly used to adjust the depth of field. This is also the most commonly used mode.

S (Shutter-Priority Mode)- Shutter Priority Mode: The user sets the shutter speed and the camera automatically calculates the appropriate aperture value, which is mainly used to take dynamic photos or night scenes.

P (Programmed Auto)- Program Mode: The user does not need to set the aperture and shutter speed, the camera will adjust them automatically.

Auto – Fully Automatic Mode: Everything is controlled by the camera, including the flash, aperture, shutter, ISO value, and more! Just lift the camera and shoot!

Use of Each Mode

M– You need to fully control the aperture and shutter, such as deliberately taking over exposure or under exposure photos in an environment where there is not much change in indoor light.

A– In most cases, you only need to adjust the “depth of field” you want, but pay attention to the shutter speed to avoid the situation where the shutter is slower than the “safe speed” and the camera shake occurs.

S– Deliberately use faster shutters to “freeze” fast objects (such as people in motion), or use slower speeds to create dynamics (such as expressing a moving car).

P– When the photographer wants to focus on composition without needing to set the aperture or shutter.

Auto– If you want to be proficient in photography, try not to use this mode.
