There are no strict rules for posing people, as posing can vary depending on the context and desired outcome of the photo. However, there are some general guidelines that can help you create more visually appealing and flattering poses:

Create a natural stance: Encourage your subjects to stand or sit in a relaxed, natural position. This can help create a more comfortable and authentic look.
Use angles: Angling the body slightly can create a more dynamic and flattering pose. For example, have your subject shift their weight to one leg or angle their shoulders to create an interesting pose.
Use props: Props such as chairs, stools, or even flowers can help create interesting poses and add visual interest to the photo.
Create symmetry: Symmetrical poses can create a sense of balance and harmony in the photo. For example, having both arms at the sides or having both legs crossed can create symmetry.
Use the rule of thirds: The rule of thirds is a composition guideline that suggests dividing the image into thirds both horizontally and vertically, and placing the subject at one of the intersecting points. This can create a visually pleasing and balanced composition.
Direct eye contact: Eye contact can create a connection between the subject and the viewer. Encourage your subjects to look at the camera or at each other to create this connection.

Remember, these guidelines are not strict rules and should be adjusted according to the context and desired outcome of the photo. The most important thing is to create a pose that is comfortable, authentic, and visually appealing.
