His father owned a business in the cotton trade and his grandfather Cels Gomis (Reus, 1842 - Barcelona, 1915) was a civil engineer with intellectual interests.
These periods abroad enabled Gomis to produce photo series based on the architecture and urban landscapes of the places he visited.
Joaquim Gomis was well-respected in artistic circles, which were somewhat taken aback when he began photographing the work of Gaudí, an architect who was underrated at the time.
Although his first series was about a eucalyptus, some of the subjects he covered were Gaudí's Sagrada Familia church, the Cathedral of Tarragona, the works of Joan Miró, and the city of Barcelona.
Exhibitions of Joaquim Gomis' work include a show held at the IVAM in Valencia in 1997, with previously unpublished images from the period he spent in the United States from 1922 to 1923.
