Morphology

photographic + emulsion

The phrase is fully compositional: 'photographic' (relating to photography) modifies 'emulsion' (a light-sensitive coating), so the combined meaning — the light-sensitive coating used in photography — is directly derivable from the constituents. Although somewhat technical, the logic is transparent and mirrors equivalent constructions in other languages, so a B1 learner who knows both words will readily understand it.

Etymology

The compound noun photographic emulsion comes from the word emulsion, which means a smooth, jelly-like mix. Photographers spread a thin layer of this jelly with tiny silver particles onto film or paper so it would 'catch' light, so photographic emulsion means the 'light-sensitive' coating used to make photos.
