The adverb is formed regularly from the technical adjective 'photometric', but the underlying scientific term is not highly accessible to typical learners.
Etymology
Photometrically comes from photo- meaning 'light' and -metric meaning 'measure', the same parts you see in photograph and in a meter that measures things. So, to do something photometrically is to 'measure it by light'.
