How to adjust the gray photography of mobile phone

high-flown words

Photos depend on which aspect you focus on, whether you want to make the white one as accurate as possible or the black one as accurate as possible ... Lesson 5 If you have a new textbook.

There is a very easy-to-understand explanation in Gao Fancha's class. There are 1 photo to make you understand ... For example, we shoot the model in the backlight, not only to make the facial details of the model clear, but also to make the model see more clearly.

sky

The white clouds in the room can also be seen, and we may have to measure the model's face ... this kind of measurement.

It is bound to lose the details of the white clouds in the sky, so we have to reduce the aperture of 1-2, so as to retain the details of the model's face to the maximum extent and see the white clouds in the sky. If the ratio of black and white is 50/50, you have to find a way.

main body

That's the background! If half is on the left and half is on the right, try spot metering ...)

2 ... white plus black MINUS ... generally for Gao Fancha scenes and

Pure white and

Atrus

You need to use it when shooting ... Of course, the subject will prevail when shooting, if the background is

White or black?

The subject is not, so we should consider the subject first, and then the background! Just like shooting snow and coal ... if you don't use the method of adding white and reducing black, you will always shoot 18% gray.

Just like me

For example! Shoot the face details of the model ... If you measure the light at a distance of 5 meters from the model, the camera gets the information that the model itself enters the lens with the sky.

bright

, and then multiplied by 18% ash.

expose

.. this goes against our original intention of wanting the details of the model's face. We should measure the model's face half a meter away or closer, so that we can accurately expose the details of the model's face ... Then we will write down this set of data and go back to the place where we want to take pictures ... According to this set of data, we can show the details of the model and the sky by adding white and reducing black. (The camera has a built-in exposure meter, which is more troublesome to use ... Besides, can you change the depth of field of the photo itself by increasing or decreasing the aperture value? What if the depth of field cannot be changed in some cases? How's this? There is a lot of noise in improving sensitivity ... with the adjustment of EV step level, the brightness increases or decreases less than 1 aperture value ... Besides, in the case of dim light, is it convenient for you to adjust EV step size or bring a tripod to open the aperture? )
