How to solve the virtual edge of product shooting?

When you shoot a product, you always shoot it as a virtual edge. I have tried all the apertures, but it will still be a virtual edge. The reason is not that I can't focus correctly, nor that the tripod causes the fuselage to shake, but the depth of field. Small items are regarded as the category of macro photography. Then pay great attention to the influence of equipment. First, the lens itself has a minimum focus distance, and each lens has a limit. For example, you can't be too close, you have to be 2 meters away to focus. The second is the depth of field. Such a small object, close range and depth of field have great influence. You can see that some objects in the picture are clear, but the different positions are blurred. This means that the blurred position is not in the focal plane of the camera, nor in the effective depth of field. Under the condition that the distance between the subject and the plane is constant, the smaller the aperture, the greater the depth of field, which is easy to focus and increases the chance of accurate focusing. Try to reduce the sensitivity and increase the aperture to make the contrast between the real color and the background more obvious. Therefore, small aperture shooting has an immediate effect. In addition, if you want to shoot more professionally, please use a macro lens.

For macro lens, if you put the subject too close, the aperture should be adjusted very small, because the depth of field of macro lens is very shallow. Generally, a macro lens is used to shoot such a big thing, and the aperture should be set above 1 1 to 16. Fix the camera and shoot with light. 50mm fixed focus, the edge is empty when the distance is close. If you use macro, try to narrow the aperture. If you don't want the aperture to be too small, don't put the object so close to the lens, that is, you don't need to shoot at the macro end. It is recommended to use Budweiser lens, which has stronger details and sharpness.
