Sigrid Viir (b. 1979) works and lives in Tallinn. Viir studied cultural theory at Estonian Humanitarian Institute, after which she acquired BA (2009) and an MA (2017) degrees in Photography at the Estonian Academy of Arts. During her studies she also completed a Media Arts exchange program at Staatliche Hochschule für Gestaltung Karlsruhe (Prof. Elger Esser).

Viir's practice - both solo and as a member of Visible Solutions LCC with Karel Koplimets and Taaniel Raudsepp - is situated between photography, installation and performance practices. Through their mostly performative practice, Visible Solutions explore the relationship between art and economy questioning the methods on which the art world operates as well as their own roles within that. Viir’s solo practice evolves around a more private sphere: family and domestic objects. The artist describes her interest to be focused on “behavioural habits and functioning models”, which she documents, questions and rearranges in her work. Viir's photo series, depicting people and objects in unexpected arrangements, often deal with functionality and structure of social models. Sigrid Viir is interested in the daily aspects of human existence and the related tangle of social agreements, the borderline between the totality of work and personal time of rest as well as the themes of visual language.​
