How to design the steel frame renderings of outdoor billboards?

Generally, we go to the scene to take photos of the advertising space, and then press CTRL+T in the photos taken back. When there is a change point, right click, select deformation, and adjust the size according to the advertising position. (If you only use PS for the effect, you'd better have a certain art foundation. Three-dimensional)

Then find a brightening or darkening tool in the toolbar and trim the whole picture according to the brightness of the photo taken. Generally speaking, the size and transparency of a pen are very important. Just click the right mouse button on the picture and select the brush you want. You can adjust the transparency in the line below the menu bar.

If you want to create a night effect, create a new layer, select it with an oval box on the new layer and draw a feathered one. Ha ha. You can do some feathering effects properly, but it is best to learn some basic 3D production. Good stereoscopic impression.

Beginners had better not do night special effects.
