The problem of white space on the top of photography

The picture composition should be coordinated, and it should not be too full. If it is too full, it will give people a sense of oppression. At this time, it is necessary to leave blank space, which can be the sky, the blurred scenery or the clean ground. In short, the blank space should be clean and concise, and it should not mislead readers' sight. It is natural to guide readers to focus on the subject.
