Polaroid SX-70/Time Zero Manipulation Technique

The Polaroid SX-70 is a camera made in the 70's that uses a unique type of film called Time-Zero. The film is not a solid, but a liquid emulsion kept in place by layer of clear plastic. Since the image is made by coloring the liquid emulsion one can be moved around while it is still soft, but in heat it begins to cool. This means one can use small tools, such as toothpicks to move the emulsion around. distorting the image and it's brightness.

This is the SX-70 Alpha 1, sold in 1977, used by artist Renata Ratajczyk published on Alternative Photography

This is the Time-Zero film used for the manipulation

This photo by Renata Ratajczyk uses the technique to make the photo look painted and brings out the contours. 

One can also move the liquid to create patterns and show movement as shown in this other photo by Ratajczyk.

Cyanotype is a process of printing photos that are the same size as the negative where you coat a paper with Ferrocyanide and put the negative or some leaves, plants, ect. on top then leaving it in the sun for a few hours to expose. The Ferrocyanide will change to a deep blue color in the places where the object or black on the negative was not. Then you wash the Ferrocyanide off and it will stay that way creating a positive or white spots where the plants were.
