Morphology

photosensitive = sensitive (transparent) = photo + sensitive

The word is a straightforward combination of 'photo-' meaning light and 'sensitive', so the meaning is directly inferable.

Etymology

Photosensitive breaks into photo- meaning 'light', as in photograph, and sensitive meaning 'easily affected'. So, photosensitive means 'easily affected by light', which is why we use it for people, film, or chemicals that change when light hits them.
