Who can help me calculate the dimming parameters of photography?

Accessories needed for shooting: tripod, polarizer, hood.

But there are some specific problems in your shooting requirements that are unreasonable.

There are some problems with your request:

1. Strong texture

First of all, the texture of the building is the same as other light absorbers, and there is no difference. As long as the exposure is accurate, the texture is not a problem, or there are more specific special requirements, such as the texture at night or in strong sunlight. Otherwise, there is no special need to shoot.

2. No depth of field relationship?

Photograph shooting must have a certain depth of field, either a large depth of field or a small depth of field. The larger the aperture, the smaller the depth of field, and vice versa.

The depth of field depends on the aperture, so the question in this requirement is to fix the aperture? You can ask the teacher again.

3. Good granular type?

First of all, the particles produced by photos are mostly affected by underexposure. Unless there are special artistic effects, photographers generally pay more attention to the control of particles. If the film grain is better, the digital grain is really ugly.

4. Does the picture take the subject as the exposure point?

Explain that the requirement is point exposure, so this requirement can only be understood as an investigation of students' exposure subjects, but the contrast between buildings is real and huge, so it can only be compared with the sky, depending on the color of the building.
