In portrait photography, avoid threads piercing the waist, that is, strings or bridges passing through the subject’s head or waist.

Portrait photography highlights the characters, so it pays great attention to the matching of characters and background.

A background with obvious line shapes appears near the head, or even clearly separates the head, neck, etc. (not just lines, bridges, etc.), which will strongly interfere with the main body of the character. Simple To put it simply, it feels awkward and loses its beauty. Therefore, the composition and framing should be avoided as much as possible.

When a similar situation occurs around the waist, the visual interference will be less than when it occurs around the head, but you should also pay attention.

Generally speaking, this problem can be solved more easily by using a large aperture lens to blur the background when shooting portraits.

If the background cannot be blurred, then the photographer's observation and composition skills are very demanding, but if used well, certain shapes of the background may be able to better support the characters.
