I made the background using 2 King sized white sheets and glued 10 lbs. of Polyfil to them.
Lighting: Behind the backdrop: 2 Godox AD 200 with blue gels. On model: 1 Godox AD200 with a 24″ Magbox Octa double diffused with a FocusDiffuser and regular diffuser on top placed camera right, almost 90 degrees from the model. I also shot in Underwater color temp mode for the overall blue effect.
