René Pauli (1935–1999) was a Swiss-American artist known for his original photographs and tri-color carbon print making process.

[1] His tri-color carbon prints of original nature photographs were sold in several U.S. photography galleries,[2] featured by an Eastman Kodak exhibition and by the Sierra Club and are included in the collections of the Metropolitan Museum of Art,[3] the Museum of Fine Arts, Houston,[4] and the Polk Museum of Art.

[5] René revived and perfected the carbon printing process independently in a small apartment in San Francisco by engineering all hand built machines, even creating his own paper mats.

His tri-color carbon prints were noted for their unmatched color, quality and detail, bas-relief effect, and archival permanence, estimated to last virtually unchanged for many hundreds of years.
