The purpose of this session is to describe and discuss the development of astronomical photometry to provide increasingly useful tests of astrophysical theories. It will focus on the achievement of precision and accuracy, and span the interval from the photovisual and photographic era to the present CCD age. Both instruments and techniques are to be discussed, and discussion will include photometric systems and transformations, absolute calibration, spectrophotometry, and polarimetry.
In this paper, the achievements and promise of improved photometric precision will include discussions of passbands, extinction, and standardization techniques in both the visual and the infrared. The infrared photometry discussion will highlight the improvements attainable by a careful choice of passbands.
In the second part of this paper, we emphasize differential photometry, especially the dual-beam instruments commonly referred to as \textit{two-star photometers} from the Princeton visual polarizing photometer, through the pioneering work by Th. Walraven in the development of precise differential photometry techniques, to the chopping, gated, pulse-counting Rapid Alternate Detection System (RAO) used at the Rothney Astrophysical Observatory.
