Theme, theme, does every photographic work have a theme, such as a picture of a bustling street scene or a picture of a big scene, with people, cars and cars?

The theme of the picture usually comes from the center or golden line of the picture, which is the main content of the picture. Usually accounts for a large proportion of the picture and has rich details. You can highlight it by blurring the background or distinguishing colors.

If a photo is taken at sixes and sevens and people don't know where to look, it is usually lack of theme and unintelligible.

And if the most prominent theme in the photo is not what you want to express, we will say it is stealing the camera.
