Believe it or not, this shot happened during a corporate headshot session.
After we finished the more formal looks required, we ended up talking about how crazy life is, and we were just cracking up. I captured this and it's my favorite picture of the shoot, although her body position changed the effect of the light a bit but that expression is unbeatable to me.
This photo ended up in a magazine article about her rather than the originally intended formal photo :)

Shot using a Sony A7 III with 3 stripboxes.
