This was from the first session in my little home studio I've been putting together. The girl is the daughter of a colleague, and they dropped by for a few minutes over the weekend - it was the girl's 4th birthday. The girl was bouncing around all over the place but just for a moment, as she was starting to get tired, she complained about a pain in her stomach and changed her expression and posture to this. I really like pose and the mood in this one - the rest were all much more smiley and bouncy!
This was shot on my trusty X100F (yes, I know, not your typical studio camera, but I love its leaf shutter...) and a collection of cheap old Yongnuo speedlights and collapsible softboxes.
