Cyanotype
The cyanotype process results in a blue image. This alternative process was first introduced to the photography world by Sir John Herschel. He fixed images using hyposulphite soda in 1839. He coated paper with iron salts and used it in contact printing. The paper was washed in water, resulting in the trademark white image on a deep blue background. The images appear painted on.

Polaroid Emulsion Transfer
A polaroid transfer is the process of stripping the emulsion layer from an exposed polaroid image and placing it on another object, usually water color paper, giving your image a new shape and creating interesting manipulations. This process was pioneered by Edwin Land, the original inventor of the polaroid instant photography. (Source: Impossible Project)
