What are the lighting layout and SLR camera parameter settings of these two pictures? Want to shoot this effect, thank you for your help!

This effect is very common, and a lamp with a reflector can cause this effect. A single lamp with a large soft cover is better, and the light coming out is softer. The role of the reflector is to control the light ratio and make the shadow transition more natural. For cameras, the aperture can be as small as 5.6-8. If double lights are used, follow the second instruction: clothes are hung on the wall, the main light is placed on the left and the auxiliary light is placed on the right, and the light ratio is controlled.

Key points: main light and auxiliary light. The light must be soft and control the appropriate light ratio.
