Is the non-mainstream photo style the same as the LOMO photo style? ?

Not the same.

First of all, the non-mainstream emphasizes posing, those with "awl faces", "V-shaped hands", and looking at the camera from bottom to top. In a word, non-mainstream means that when you are taking a photo, the subject knows that you are I am taking pictures of him, and I am deliberately posing in various poses; LOMO photography emphasizes a kind of casualness, which in layman's terms is a snapshot, where the subject quickly presses the shutter without the subject knowing anything about it.

Secondly, for non-mainstream photography, you need to pose properly, take a preliminary view through the viewfinder, and then press the shutter button. You can know the effect at that time. However, LOMO photography does not require a good posture. Some LOMO cameras do not even have a viewfinder. Shooting based on the photographer's feelings, LOMO plays with the uncertainty of the photos after they are released.

Nowadays, some non-mainstream people deliberately imitate the LOMO style and perform post-PS. In fact, the difference between the two can be seen in the form of photos.
