Boulton was also an active photographer; his work is held in the permanent collection of the Museum of Modern Art in New York City.

After returning to Venezuela, Boulton's work turned toward depicting and engaging with his home country.

[6] The following quote from Boulton illustrates the connection that this documentation of ceramics has with his overall approach to Venezuelan art history: It is true that indigenous Venezuelan culture has been relatively little studied: but even so, such testimony as I have described is appropriate for my purpose, which is – as I must state at the outset – of a purely aesthetic and not an anthropological kind.

[1] He was also a friend to international artists, notably, Alexander Calder designed a piece of kinetic art for his living room.

[12] The Getty Center houses a collection of his artwork and writings (many previously from the Alberto Vollmer Foundation), a selection of which were on display in the exhibit Alfredo Boulton: Looking at Venezuela, 1928–1978.
