Dryad and Dark Angel are in-camera multiple exposures using studio strobes and a black background, with some Photoshop post-production work. With Dryad (above), the model used the multiple exposures to intentionally form a tree-like shape. Later, in Photoshop, I added the exterior textures of branches of a tree to give the sense that the model was an exemplar of the divine spirit in a tree, or in other words, a Tree Goddess, a Dryad.
With Dark Angel (below), the wing-like effect around the model’s upper arms was creating when she moved a black, translucent fabric while making the exposures. I positioned her in the frame you can see in Photoshop.
