During the Colombian period, he stated that each of his works were inspired by a poem of Fernando Pessoa, whom he considers the "poeta del desasosiego" (poet of disquiet).[4]
His one-month solo ultrarealist art exhibition, "Parejas" ("Couples"), at the Beatrice Brunner Gallery in Bern in 2006, displayed seven diptych paintings depicting seminude individuals in pairs but separated deconstructively by whitespace, staring at the viewers.[5][6] One half of one of the diptychs was stolen prior to the exhibition. Inspired by Fischer's study of the historical artistic representation of relationships in society and painted over the course of five years, the enigmatic paintings emphasize the necessity of individuality in all relationships;[7] the relationship between the couples is left unstated.[5] Fischer explained, "It was intended that the couple needs a space and that that space contains a distance between the two individuals, and that that space is important."[7]
Paintings in the photorealist series include Carolina and Juan (2004), in which Juan, on the edge of the painting, appears indecisive about remaining in the image or abandoning the common space; Lauren and Dean; Maria and Deuxchevs (2006); Ralph (2003); and Sarah and Michael.[2][5][7] They were painted according to photos taken of the model couples early in the morning, shortly after waking, to obtain intimate portraits. The whitespace was inspired by Wanderer above the Sea of Fog, by Caspar David Friedrich,[5] while the distance between each couple was inspired by royal portraiture such as Francisco Goya's painting The Family of Charles IV. Curator Beatrice Brunner stated that reception was "magnificent": patrons included Berner Zeitung journalist and critic Konrad Tobler, and painter and philosopher Angelica Baum.[7]
These paintings were re-exhibited when Fischer, and three older Colombian artists who had immigrated to Switzerland since 1972, participated in a joint exhibit commemorating the centennial of the Colombian-Swiss peace treaty of March 14, 1908.[2][8] Colombian ambassador Claudia Jimínez sponsored the exhibit,[8] and critic Tobler stated that Fischer's art focuses much more on the psychological aspect than the photographic, in the photorealist tradition.[3]
