Between 1930 and 1933 the CCE dealt with matters concerning photometry. The Consultative Committee for Photometry (CCP) was set up in 1933, and its name was changed to Consultative Committee for Photometry and Radiometry in 1971.

Present activities concern measurement standards for photometric and radiometric quantities, development of absolute radiometry, and advice to the CIPM on matters concerned with radiometry and photometry.
