Encaustic Photography involves the application of layers of an encaustic medium (a mixture of beeswax and damar resin) upon a photograph that has been adhered to a substrate (usually wood) and fused in with heat to become one unified piece. Upon the wax layer, pigments, paints, inks, thin papers, dried botanicals, encaustic paint, tinted medium and image transfers can be applied. Layer upon layer of wax and artistic techniques are built up, with each layer being fused together as the process continues. Wax can be applied in smooth, translucent layers or textured.
For me, encaustic photography is a way to take back the more tactile manner of working with photographs, as opposed to a purely digital manner. It's a technique that is highly creative and pushes the boundaries of a photographic image.
