Take a picture of the bathroom pendant. I have a 6D Canon camera with an indoor space of 30-40 square meters. Which lens to configure is good, and the skills are also recommended. Thank you!

It doesn't matter what kind of lens you use, what matters is the lighting and post-adjustment. Judging from the picture, at least two light sources should be arranged on the picture, one is the main light from the front of the clothes rack, and the other is the side light from the position where the photographer is standing. After the background is trimmed, it is changed to this background, then PS shadows and some highlights are added to modify the defects. So it is obvious that this kind of shadow and light is against the visual habit. However, from the analysis of the distortion degree of the picture, it can be basically determined that it was shot under a 50mm standard lens.
