The way she moves is something soooo beautiful, you can't help but let her do. Continuous light was not available at the studio (no LED lights, no sunlight) so I had to go ahead and work with flashes (which i really dislike).
often i get asked why (most photographers work with flash)... well... models then know perfectly well when you click and often go into "work mode", pose after pose after pose instead of flowing. Thanks to Erika that understands perfectly that for me images are only possible when we are constantly moving so body work and energy is not lost.
