How to use the settings of Nikon SLR entry-level camera?

A gear (lens priority): Aperture priority selection, other functions automatically match the aperture selection. Users only need to adjust the aperture, and the program automatically determines the shutter value. Suitable for shooting landscapes, portraits and other subjects. Precautions for use: If you want to clearly understand the brightness of the subject at that time, select the aperture setting.

S mode (speed priority): Shutter priority selection, other functions automatically match the shutter selection. Users only need to adjust the shutter value, and the program automatically determines the aperture size. Suitable for shooting sports, capturing dynamics and other subjects.

SLR photography skills: First of all, you must understand the meaning of the so-called aperture, shutter, focus, color temperature, white balance and other values. Secondly, you need to understand the impact of each value on other values. For example, if the aperture is too large, you need to speed up the shutter speed appropriately to ensure that too much light is taken in, resulting in serious exposure and whitening.

Basic settings for SLR photography: choose the aperture that is the middle value of the lens you are using. Under normal lighting, choose a shutter speed of 1/60, and choose an ISO sensitivity of about 200 for daytime photography. Photos taken with an ISO that is too high will have a lot of noise. By setting these three values, you can handle most daytime scenes, and you also need to learn the correct posture to hold the phone.
