Image Manipulation
One feature of SX-70 integral print film is its ability to be manipulated while developing, and for some days after. Because the emulsion is gelatin-based, and the Mylar covering does not allow water vapor to readily pass, the emulsion stays soft for several days, allowing artists to press and manipulate the emulsion to produce effects somewhat like impressionist paintings. An example of this technique was used on the cover of Peter Gabriel's third album, Peter Gabriel.
The 500, 600, and Spectra/Image materials do not use a gelatin-based emulsion, and cannot be manipulated this way.
Manipulation of the photograph is best done about two minutes after the picture has fully developed. It will stay soft and workable for about 5–15 minutes. Some colors will be more difficult to work on (dark green), whereas others are workable for a long time (red). If the photo is on a warm surface or slightly warmed in an oven, image manipulation is made easier.

Famous quotes containing the words image and/or manipulation:
“I know not what the younger dreams—
Some vague Utopia—and she seems,
When withered old and skeleton-gaunt,
An image of such politics.”
—William Butler Yeats (1865–1939)
“The basic tool for the manipulation of reality is the manipulation of words. If you can control the meaning of words, you can control the people who must use the words.”
—Philip K. Dick (1928–1982)
