How does Nikon D5 turn off the back screen and keep it on?

There are many preset modes for digital cameras to choose from. These preset programs allow you to choose the appropriate shutter speed and aperture value to shoot. For a novice, these patterns are very useful. Moreover, in order to capture some quick shots, some professional photographers also choose the preset mode. You need to know and skillfully use the various modes in the camera, but remember that the preset modes of different cameras may be slightly different. The following are some of the most common:

1. Automatic

Shutter: 1/64s aperture: f/5.6 sensitivity: 1 flash: Off

Automatic exposure The camera chooses the best shutter speed, aperture value, sensitivity and flash setting, all you need to do is aim at the subject and press the shutter. If you don't know anything about photography but have to take pictures quickly, that's good. Under the condition of sufficient light during the day, you can take photos with very accurate exposure. But when the light is not uniform, the camera may turn on the flash unnecessarily.

second, portrait mode

shutter: 1/2s aperture: f/4 sensitivity: 2 flash: turning on

portrait mode will "think" that the subject it is going to shoot is in the foreground of the picture, and choose a shallow depth of field to ensure that the focus is on the person and the background is blurred. If the camera thinks the scene is dark, it may force the flash. Forced flashing is very useful when the sun is strong and casts a deep shadow. Portrait mode usually performs better when there is enough light.

macro mode

shutter: 1/2s aperture: f/3.2 sensitivity: 1 flash: on

macro mode is very useful if you want to shoot something smaller than your hand. Macro mode can't help you take big close-ups unless you use a macro lens. Macro mode is suitable for use in bright environment. It will set a shallow depth of field and focus on the object. Therefore, a tripod should be used when the light is dark. You need to focus very carefully and accurately, because macro mode usually has a very shallow depth of field and can tolerate less errors.

iv. Scenery mode

Scenery mode usually sets a smaller aperture (a larger number of apertures) so that the picture can be clearly imaged from the foreground to infinity (on old cameras, "infinity" is represented by the symbol "∞"). The scenery mode is more suitable for wide-angle lenses and is also suitable for use when there is sufficient light. The camera will turn on the flash when it thinks the foreground is dark, but you can turn it off manually.

shutter: 1/1s aperture: f/16 sensitivity: 1 flash: not turned on

v. sports mode

shutter: 1/75s aperture: f/9.5 sensitivity: 2 flash: not turned on

sports is a fast-paced activity, so sports mode will choose a higher shutter speed. Higher shutter speed can freeze the instantaneous motion, which means there is no need to turn on the flash-this mode is also suitable for daytime. Sport mode is suitable for fast continuous shooting mode-you can capture a series of images of people in mid-air.

VI. Night portrait mode

Shutter: 1/5s aperture: f/4 sensitivity: 32 flash: On

In night portrait mode, the camera will try to balance the relationship between the dark background and the exposure required by the foreground subject. In order to shoot a clear background, the aperture needs to be opened large enough to get enough light. But at the same time, it is also necessary to turn on the flash to illuminate the face of the person to avoid blurring caused by the low-speed shutter. Some night portrait modes can flash twice to create an unusual double exposure effect.

VII. Advanced mode

Most digital SLR cameras also have several modes represented by letters-manual (M), aperture priority (Av), shutter priority (Tv or S) and program (P). Manual mode allows the photographer to manually set any parameters of the camera; In aperture priority mode, the photographer determines the aperture value, and the camera automatically sets the shutter speed; In shutter priority mode, the photographer sets the shutter speed (for example, when shooting a moving object), and then the camera automatically sets the aperture. The program exposure mode is similar to the automatic mode-the aperture and shutter are set by the camera, but the photographer can adjust the shooting and image-recording functions (? ）。

Summary

Some people think that only non-professionals will use the preset mode. In fact, sometimes if we are in a hurry to shoot, it is too late to manually adjust the parameters. Using different modes can teach you how to make the best settings in different situations. If you are in doubt, you can also use the automatic mode first, and then adjust it manually. Automatic mode is for use, try to understand and be familiar with each setting.
