I shoot a lot of theatrical performances and sometimes my favorite shots come from the rehearsals. It's a lot of long days to put together a show.
The stage isn't set, there are no costumes and the actors deep in the process of preparation.
Downtime between your turn to rehearse can be hours. And during those times I see the best images.
Here's another image from my Girlfriends series and it will always be one of my personal favorites.
