Camera m file:
What is an M file:
M is a full manual mode, which requires us to adjust every parameter of the camera, including aperture, shutter, sensitivity, white balance and other parameters. It is flexible and can be adjusted to get the desired effect. Such as slow door scenery, taillight painting, etc.
Three elements of M document exposure:
Aperture: controls the amount of light entering the lens. The smaller the value, the brighter the picture.
Shutter: control the camera's light entering time. The faster the shutter, the brighter the picture.
Sensitivity: the sensitivity of a photosensitive element to light. The larger the value, the brighter the picture.
Adjust the aperture:
1, aperture affects the amount of light entering (photo brightness)
The picture darkens: the larger the aperture f value, the darker the photo;
Brighten up the picture: the smaller the aperture f value, the more light enters and the brighter the photo.
2. Aperture affects depth of field (background blur)
The picture becomes clear: the greater the aperture f value, the greater the depth of field and the clearer the picture;
Blurred picture: The smaller the aperture f value, the smaller the depth of field and the more blurred the picture.
3. The aperture affects the light source (point/light)
Turn into light: the larger the aperture f value, the longer the light, and the optical fiber gradually turns into light;
Turn into light: the smaller the aperture f value, the shorter the light, and the light gradually turns into light.
Adjust the shutter:
First, the bad environment light and shade:
1, strong light, use fast shutter;
2, dim light, use a slow shutter;
(The above premise is that the aperture and sensitivity ISO remain unchanged).
Second, the moving speed of the subject:
1. Take a stop-motion picture and use a shutter speed equal to or faster than the moving speed of the object.
2. Shoot the motion trajectory with the shutter speed equal to or slower than the moving speed of the object.
Adjust the sensitivity:
We need to adjust the ISO sensitivity according to the lighting environment. The higher the sensitivity, the brighter the photo and the worse the photo quality. The lower the sensitivity, the darker the photo and the better the picture quality.
Common aperture numerical reference:
