A headshot is a close up of your head and upper torso. You could take some different shots, but close ups help others connect and are the ones that most media outlets will request. Think of people who resonate with you and have a look at their headshots for inspiration. Standing at 6'2", I have presence, I am very confident when it comes to knowing who I am and I like to make work fun but I'm also an introvert, a thinker and can be very serious when I'm focused so I opted for poses that reflected these aspects of myself. Think about what you value and which poses would best reflect that: laughter, leaning in to the camera, power poses etc and do your research. If it doubt, take some at home beforehand and test them out!
