For this shooting I use two sources.
To get maximum accutance for a beautiful contrast with enough softness to the skin, I chose to use a key-light beauty bowl large diameter and depth: the bowl "Mola Setti" accompanied by a diffusion canvas.
To highlight the structure of the blouse, I use a snoot.
In order to keep rendering homogeneous and fill-light to the hair, I use a V-Flat (can be replaced by a large reflector). All on a foldable black background.
No retouching smoothing is applied to the skin of the face of Theia, the result on the rendering and texture of her skin is a direct result of the shooting, only a slight imperfection was corrected.
I use Elinchrom generators (Ranger Quadra RX or the choice of mobility system and power output) for this setup I advise pretty powerful flash (400 or 500 joules may agree).The snoot at a fairly low return and demand significant power.
