Length is a measure of distance. In the International System of Quantities, length is a quantity with dimension distance. Length is commonly understood to mean the most extended dimension of a fixed object. However, this is not always the case and may depend on the position the object is in. Using creative photographic techniques and captured entirely in camera this project playfully visualises the seven base quantities. A base quantity is a physical quantity in a subset of a given system of quantities that is chosen by convention, where no quantity in the set can be expressed in terms of the others. The International System of Quantities (ISQ) defines seven base quantities: Electric current, Length, Luminous intensity, Mass, Amount of substance, Thermodynamic temperature and Time.
