How to learn to pose?
There are no rules or secrets.
All you need is to be yourself and do whatever you want.
I give you a plot, an idea, and suggest what to do but how will you do it depends on you.
Imagine you are alone and there is no one else. Abstract of everything, do not pay attention to anything. You are living your life. My task is to take photos while you are living the life.
Not everyone came up as an actor and able to become an actor. But it is important to develop these skills for your own history, for your own photos. Try to be different on each photo. Do not be the same. Do not strike the same poses, do not use the same plots, and do not make the same facial expressions. And you will see your acting abilities, and your imagination and individuality will wake up.
