Or take photos with automatic file _ set M file tutorial.

I'm still taking pictures with automatic gear. The following is a tutorial on setting up an M file.

What is the M file of the camera? The M file of the camera allows the photographer to adjust the shutter speed and aperture size according to the shooting scene and environment, as well as the needs of the photo, so as to obtain the best exposure effect. Step 1: Turn the turntable at the top of the camera to M position. Step 2: Adjust in the camera parameter interface.

How to adjust exposure correctly: exposure is what we often call "photo brightness", which can be adjusted by shutter, aperture and sensitivity. Normal exposure means that the brightness of the photo reaches the internal calculation standard of the camera. Adjust the aperture: open the aperture and the exposure value will decrease; Close the aperture and the exposure value will increase. Adjust the shutter speed: increasing the shutter speed will reduce the exposure value; Lower the shutter speed and the exposure value will increase. Adjust ISO sensitivity: increase ISO sensitivity and exposure value will increase; If the ISO sensitivity is lowered, the exposure value will be lowered.

Three Elements Exposed by Moving Files

1. What is the shutter?

Shutter is a device that controls the time when light enters the camera. By controlling the opening and closing time, the time when light enters the camera is controlled, and then the exposure is controlled. The larger the shutter value, the slower the speed, the more light entering and the brighter the photo. The smaller the shutter value, the faster the speed, the less light entering and the darker the photo. It should be noted that according to the speed of the shutter, it can be divided into slow shutter and fast shutter. The slow shutter can be used to shoot trajectory effects, and the high shutter can be used to capture and shoot moving objects.

2. What is an aperture?

The device for controlling the amount of light entering the lens can control the amount of light entering by adjusting the numerical value. In cameras, f is usually used to indicate the aperture. The smaller the f value of the aperture, the more light enters, and the larger the aperture, the better the blur effect. The larger the f value of the aperture, the less the amount of light entering, and the smaller the aperture, the worse the blur effect. Note: the size of the aperture will affect the depth of field of the photo. The larger the aperture, the smaller the depth of field, and the smaller the aperture, the greater the depth of field.

3. What is sensitivity?

Sensitivity is used to indicate the sensitivity of the camera sensor to light, which is expressed by ISo on the camera, such as Is 100, 15200, etc. The greater the sensitivity, the more sensitive the sensor is to light, the more exposures, the smaller the sensitivity, the less sensitive the sensor is to light and the less exposures. Note that the greater the sensitivity, the better. Too high sensitivity will affect the image quality. For daily shooting, it is recommended to adjust the sensitivity to 100.
