Morphology
photogelatin + process
The compound 'photogelatin' is not a common lexical item, but its constituents 'photo' (relating to light/photography) and 'gelatin' (a protein substance) are transparent, so a B1 learner who knows those words plus 'process' could plausibly infer this refers to a photographic/gelatin-based method. However, the exact technical sense (a specific photomechanical printing method using glass plates and image transfer) is specialized and not fully predictable from the parts, making the expression only partially transparent.
Etymology
Photogelatin process comes from how prints were made: a glass plate was covered with gelatin and put in light so the photo image became fixed in the gelatin. That treated plate was then used to 'transfer an image' onto paper, so the name now means a printing method using gelatin on glass to make pictures.
