In some higher-end DCs and all DSLRs, you can also see the options of M Av Tv P and AUTO. So what exactly do these English words represent?

M (Manual Mode)-Full manual mode: both aperture and shutter speed can be set by the user. If you need to fully control the aperture and shutter to achieve a certain purpose, such as deliberately taking over exposure or under exposure photos in an environment where the indoor light will not change much

Av (Aperture-priority Mode): the user sets the aperture value, the camera automatically calculates the appropriate shutter speed, mainly used to adjust the depth of field, this is also the most commonly used mode. This function is suitable for works with special requirements for depth of field, such as highlighting the subject and blurring the background or making the entire scene clear. In most cases, you only need to adjust the “depth of field” you want to have, but pay attention to the shutter speed to avoid the situation where the shutter is slower than the “safe speed” and jitter occurs.

Tv (Shutter-priority Mode): The user sets the shutter speed, and the camera automatically calculates the appropriate aperture value, mainly for shooting dynamic photos or night scenes. This function is suitable for works with special requirements for moving objects or people. For example, increasing the shutter speed can capture clear moving objects or people, and reducing the shutter speed can capture dynamic objects or people. Deliberately use a faster shutter to “freeze” fast objects (such as people in motion) or use a slower speed to create a sense of movement (such as expressing a moving car)

P (Programmed Mode) : the user does not care about the aperture and shutter, the camera will automatically calculate. You don’t want to worry about aperture or shutter when you need to concentrate on your composition

A (Fully automatic Mode) : equivalent to a point-and-shoot machine, everything is also controlled by the camera, including flash, aperture, shutter, ISO value, etc., just lift and shoot. If you want to learn photography, do not use this mode.
