Ask for advice on how to get these two and explain them in detail. I groped for a long time on ps, but I couldn't solve it, which shows that I am very sad.

What's so special about the picture? This is a low-key photography technique: take a photo with black as the main tone in front of a dark seamless background.

In the picture, the top light and the side top light are the main lights, which makes the figure's clothing level obvious and the projection on the ground clear. At the same time, scattered light is used on the front to supplement the light on the front, so that the front details of the characters are delicate. If you turn on the backlight, you can draw the lines of the characters better.

The key to photography is the processing when shooting, and the PS in the later period only repairs the photos.

Seamless background is the arc connection between the wall and the ground, and there is no seam between the wall and the ground, which makes the background seamless, which is more common in photography studios.

Of course, the seam between the wall and the ground can be removed by PS. There are many special filters in PS, which produce chord effect, but the picture quality is unnatural.

You should read more photography magazines when playing computer PS. What you can do in the early stage can reduce the workload in the later stage.
