What is KBr?

KBr Barcelona Photo Center
KBr is the chemical symbol for potassium bromide, a salt used in the analogue photography development process. Its main function is to slow down or delay the action of the developing agent, to prevent the formation of what is called a chemical veil, which allows obtaining a greater purity of the whites of an image.

KBr expresses the continuity of our exhibition project as well as our commitment to collaborating with other Catalan institutions focusing on photography, to being involved in training future generations in the understanding of the photographic language and to contribute, from the fascinating life witness that photography represents, to the international projection of Barcelona’s creativity and energy.

«This new project expresses the interest of Fundación MAPFRE in reinforcing its contribution to the energy and projection of Barcelona through artistic photography».
