1848 A. Claudet in London, Edinb., & Dublin Philos. Mag. 33 331 I have called it a photographometer, because it indicates the combined results of the photographic operation.

1853 R. Hunt Man. Photogr. (ed. 3) 149 M. Claudet turned his attention to contrive an apparatus by which he could test at the same time the sensitiveness of the daguerreotype plate and the intensity of light. This instrument he called a Photographometer.

1868–9 Proc. Royal Soc. 17 p. lxxxvi His dynactinometer, his photographometer..and other results of his experimental researches are familiar to most photographers.

2. A rotating camera in which the image is focused by a prism on to a horizontal glass plate, producing an image which accurately represents the angular position of surrounding objects relative to the camera. rare.
