What is the use of professional photography in mobile phone photography?

Taking photos with mobile phones has become very convenient in daily life, and many people can't work without mobile phone licenses. With the emergence of smart phones, taking photos is not limited to using digital cameras and professional SLR cameras. Tourist attractions, beaches, amusement parks, etc., people with mobile phones can be seen everywhere. The camera function of mobile phones is also constantly improving. Smart cameras of mobile phones make more and more people like to take pictures, and friends circle is full of various photo shows and beauty shows.

Today, let's talk about some unusual functions of our mobile phone camera. In addition to automatic mode and various preset modes, mainstream flagship smartphones also have a very powerful professional mode, but some friends have been buying mobile phones for a long time and have never understood what several terms of this professional mode are for, or have never used them at all. Let me introduce you. Memorize these five nouns and understand their relationship, and your photos will be different.

The picture below shows my mobile phone in the frame of the camera. If you hold down the border, a focus frame and a light measuring frame will appear, and you can drag the light measuring frame to select the position of the light source at will. The metering frame of some mobile phones is automatic and does not support manual operation.

The following is a picture comparison of the metering frame in different positions.

All on the same object, belonging to the default mode.

Select different objects in the metering box, and the light will be different according to different objects.

Common mobile phone manual mode (or professional mode) is generally divided into five modules: metering mode, sensitivity, shutter speed, exposure compensation, shutter speed, manual focusing and white balance. (The following order is from left to right, and different mobile phones have different locations. )

My mobile phone is called professional photo taking.

white balance

White balance is actually an abstract term. In order to make you understand better, let me make an analogy.

For example, a piece of white paper under a candle, what color is it? What color are the white paper at dusk and the white paper in the morning?

Because our visual system will automatically adjust according to the light conditions, no matter what light we look at, a piece of white paper will always be white, but the camera is different. The camera will only faithfully record the color in front of us, so in the warm light, the white paper you shoot is yellowish; In the cold light, the white paper you shot is blue. If you don't believe me, you can try now.

Adjusting white balance is the process of adjusting white objects. As long as the white object accurately restores the white on the screen, other objects will accurately restore its original color.

In the professional mode of general mobile phones, in addition to the automatic white balance, a variety of white balance adjustments are preset, usually: cloudy days, fluorescent lights, sunshine, etc. , sunny day.

Simply put, these white balance modes are that you can manually select the preset white balance when you feel that the color temperature of automatic white balance shooting is inaccurate.
