Morphology
photometry = photo + metr + y
The meaning is built from the scientific combining form photo- and the measurement root metr-, but the technical morphology is not fully transparent to average learners.
Etymology
Photometry comes from Greek parts photo- 'light' and -metry 'measure', where photo- is the same start as photo or photograph and -metry is like in thermometer or a water meter. So photometry literally means 'measuring light', which is why it is the science of measuring the brightness and amount of light.
