I bought a background support and some black muslin recently. I have played with this set up at home, but this was my first opportunity to use it with live models. We were in a large studio as the group had planned to rehearse after the photoshoot so there was plenty of room and plenty of light. I used a couple of the studio's built-in spotlights as continuous light sources rather than use my speedlights.
What have I learned?
These dancers all had poses worked out in advance and in view of the purpose of the photographs, they are highly stylised. However, I still think their individual personalities shine through.
I had to darken the background in Photoshop so, in future I need to try and underexpose the background at the time of capture. In some instances, a bit of back/rim lighting would have been useful to lift the subjects from the background.
