What are the types of camera projections?
Cameras had two main projection modes, one was an ortho-projection, and the other was a perspective projection. In an ortho projection, the distance between the object and the camera had no effect on the rendering result. No matter how far the object was from the camera, the size of the rendering would be the same. This kind of camera was usually used in two-dimensional games, also known as parallel projection. It could project all the objects in the scene onto the observation plane through parallel light rays. The effect of perspective projection was closer to the real world. The farther away the object was from the camera, the smaller it would be rendered. Perspective projection used a pyramid as the viewing cone, and the camera was located at the top of the pyramid. The pyramid was cut off by two planes to form a prism. Only the model inside the prism was visible. Its purpose was to transform the prism into a cube, thus producing the effect of near big far small.

There are several types of storage format in the camera
The storage format in the camera was commonly used, such as JPEG, TIFF, RAW, etc. It might even support the HEIF format. Different storage format had their own characteristics. For example, the JPEG format was a loss-compression format. The file took up a small space, was fast to read, and was easy to view, but the post-processing space was limited. The RAW format was a raw data format, which retained the original information of the shot and had more post-processing space. The TIFF format was a non-compressed format. The HEIF format could greatly reduce the file size while ensuring good image quality.

What are the best types of camera shots for shooting jewelry?
When shooting jewelry, a macro lens was the most suitable type of lens.

This lens can make the camera reach 0.5 times when it is not far from the subject. If conditions permit, it is better to buy a macro lens that can shoot at a 1:1 ratio. In addition, standard lenses such as 50/1.2 or 1.4 could also be used to shoot jewelry. Canon's TS-E45/2.8 or TS-E90/2.8 could also be considered.
