How to take a close-up shot with SLR?

SLR close-up can rotate the focal section to a wide angle and set a small aperture of more than 8 to ensure a clear background. If possible, try to preview the depth of field, or visually observe the depth of field effect through screen capture. Don't stand too close to the subject and don't pull the lens too close to the subject.

Single-lens reflex is the most popular viewfinder system, which is used by most 35mm cameras. In this system, the unique design of the mirror and prism enables the photographer to directly observe the image passing through the lens from the viewfinder. Therefore, you can accurately see the same image that the film is about to "see".
