Morphology

quarter + plate

The compound is compositionally interpretable—'quarter' suggests a one-fourth size and 'plate' is a flat sheet—so a learner can infer it denotes a plate of reduced size. However, the exact photographic sense (a specific historical plate format and its precise dimensions) is domain-specific and not fully predictable from the parts, making the expression only partially transparent to a B1 learner.

Etymology

Quarter plate comes from early photography. A plate was a thin glass sheet put inside a camera and quarter shows it is about one quarter of a full plate, so the phrase means 'a small photographic plate'.
