Morphology
emulsion = emulsify (opaque) = emuls + ion
Although formed from 'emulsify' + '-ion', the photographic technical sense is specialized and not easily inferred by average learners.
Etymology
Emulsion comes from the Latin root emulgere, which means 'to milk'. Think of a thin, 'milky' coating on film where tiny particles that are 'sensitive to light' sit in a clear jelly, like fat droplets in milk. So a photographic emulsion is the thin layer that holds and records the image.
