Private photography 18

1 ... If you take photos of Gao Fancha, it depends on which aspect you focus on, whether you want to shoot the white one as accurately as possible or the black one as accurately as possible ... If you have a new photo textbook, Gao Fancha Lesson 5 has a very easy-to-understand explanation, and there are 1 photos for you to understand ... For example, when we shoot models in backlight, we also want to. We may need to measure the model's face ... and such measurement will inevitably lose the details of the white clouds in the sky, so we have to narrow the aperture of 1-2, so as to preserve 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 to be both the subject and the background! If half is on the left and half is on the right, try spot metering ...)

2 ... white plus black minus ... usually used in Gao Fancha scenes and pure white and pure black shooting ... Of course, the subject is the subject when shooting. If the background is white or black and the subject is not, consider the subject first, 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.

3 .. cameras are stupid ... they don't know how to measure light. You know how to measure light. They are just tools. Just like the example I gave! Shooting the details of the model's face ... If the light is measured at a distance of 5 meters from the model, the information obtained by the camera is that the model itself adds the light from the sky to the lens, and then multiplies it by the exposure of 18% gray level ... 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? )
