The surface of leather shoes is too smooth, which belongs to reflector. When shooting this kind of object, you can make a "box" with sulfuric acid paper (that kind of translucent hard paper) and dig a hole with no bottom on the side facing the lens, so as to avoid stray light reflected from the surface of leather shoes. The hole doesn't need to be too big, and the lens can be taken completely. As shown in the figure. This smooth and reflective object can do this, and the effect is very good.

You can get the correct exposure without an exposure meter, but you need to try more and have a concept of exposure value.

Two lamps are used to shoot portraits, probably large flat lamps. The camera can set the focus mode in advance and change to multi-point focus, and the color difference will be automatically considered when the camera is exposed. In the case of poor grasp, underexposure is better than overexposure, leaving room for later repair.
