Photo plus photo parameters

When shooting different portraits, there are actually many different parameters that can be set. Different scenes are suitable for different parameters. As long as it is suitable for the current scene, it is the most suitable parameter. For me, the most important thing to take a portrait is the following two aspects for your reference.

1,? Camera parameters

The parameter setting of the camera is simpler than that of the lens. The most important thing is to ensure that the photos taken will not affect the out-of-focus portrait because of hand shaking. As long as you master the following gears skillfully, you can easily take your own satisfactory portrait photos. The following three parameters will have different effects on photos.

l？ hole

The aperture on the camera determines the speed of the shutter. If the light is insufficient, the photo will turn black or blurred. So the appropriate aperture is very important. Apertures can be divided into the following two types for reference:

1) large aperture: it can blur the edges and backgrounds of people and give people a dreamy atmosphere. It also makes the characters in the picture stand out, the main purpose is to stand out people or objects.

2) Small aperture: Compared with the large aperture, the small aperture has deeper depth of field and richer background details. Proper use can make people and backgrounds very colorful.

l？ shutter

The shutter speed can be determined according to the focal length of the lens. The smaller the focal length, the slower the shutter speed. Relatively speaking, if the telephoto uses a slow shutter, the photos taken may be blurred because of jitter. Shutters are divided into high-speed shutter and low-speed shutter.

1) high-speed shutter

Suitable for people who need to shoot fast movements such as shooting sports.

2) Low speed shutter

It can be used for creative portrait photography, such as streamer portrait and portrait with slow background.

l？ International Organization for Standardization (ISO)

Sensitivity determines the lower and upper limits of aperture and shutter. Generally speaking, the lower the ISO is, the better, but it must be adjusted according to the different situation on site. Too high iso can ensure the shutter speed and aperture size, but the noise relative to the photo will increase. If you want to get a sense of film when shooting portraits, you can actually improve iso to make a little noise.

2,? Selection of lens parameters. Lens is the parameter that directly affects the shooting effect among all parameters. The parameters of the lens are also divided into two points:

l？ The focal length of the lens

If you want to take pictures of portraits or people, you need a lens of 50~ 100MM, which can highlight the people and separate the background. Telefocus can get a stronger sense of spatial compression, less distortion compared with people, and closer to the appearance of the subject. On the contrary, if you want to take portraits with scenery, you can choose 24, 28 and 35MM. These types of lenses can accommodate more scenes besides smaller depth of field, and greater distortion can make people look different and interesting.

L the aperture of the lens.

At the same focal length and distance, the larger the aperture, the more blurred the background. For example, the aperture of f 1.4 is definitely better than f4.

As long as you can skillfully use these parameters, you can shoot people at will.
