What does Canon EOS 50D camera S P L M mean?

(1)Auto As the name suggests, this is a fully automatic gear. In traditional cameras, Auto will set a shutter and an aperture based on the built-in light meter. It’s that simple. All you need to do is press the shutter button. That's it. In DC, the camera has to do one more step, which is white balance. Of course, in the default mode, it is also auto white balance.

(2)A The so-called A mode refers to the aperture priority mode. Aperture priority, in this setting all you can adjust is the aperture, and the camera will give an appropriate shutter speed based on the built-in light meter to ensure the correct exposure. Of course, you can also manually control white balance, exposure compensation, and metering mode, which Auto cannot. Then let’s call it semi-automatic. Aperture priority can control the depth of field very well. If you understand the principle of reciprocity, you can also easily control the shutter speed with aperture (the larger the aperture, the faster the shutter and vice versa). So this gear allows you to complete basically all your shooting work. Of course, be careful about shutter overflow (the shutter speed is too fast at a large aperture and exceeds the rated speed of the camera. At this time, the camera will prompt).

(3) S S mode is just the opposite of A mode. It is a shutter speed priority mode. In this mode, what you can adjust is not the aperture, but the speed. Of course, you can also adjust things like white balance, exposure compensation, metering mode, etc. The camera will give you a suitable aperture based on the speed you selected. , this mode is generally used for sports photography, or fixed-speed photography. For example, if you want to shoot water, you need to fix the shutter speed to 1/4. At this time, it is best to use S mode. However, please note that S mode will cause aperture overflow (exceeding the maximum aperture at high shutter speeds, or exceeding the minimum aperture at slow shutter speeds). You can also adjust the aperture via speed according to the reciprocity law.

(4)P The p file is a program file, program exposure. In fact, to put it bluntly, it is a combination of A file and S file. In this file, you can adjust the white balance, exposure compensation, and metering mode. The camera will give you a set of reasonable aperture-shutter combinations based on the built-in light meter. You only need to use the dial to select a suitable one from the middle. In this mode, you don't have to worry about overflow. Others are the same as A/S.

(5) M The M mode is a fully manual mode. In this mode, most cameras will turn off the built-in light meter. Although the aperture speed can be adjusted, if you are inexperienced and do not have an external light meter, this mode It is easy to be underexposed or overexposed, so use M mode only in some extreme situations.
