Morphology
photometer = photo + meter
The sense is compositional as 'photo-' refers to light and 'meter' to a measuring device, but both are learned combining forms rather than everyday words.
Etymology
Photometer comes from the parts photo- 'light', the same root as in photo or photograph, and -meter 'measure', the same idea as in thermometer. So a photometer is a tool that measures how bright or strong light is.
