Morphology
The phrase combines the adjective 'orthochromatic' (sensitive to blue/green but not red) with the noun 'film', so the overall meaning is directly derivable from its parts. Although somewhat technical, the compositional structure is straightforward, so a learner who knows both constituents will understand it.
Etymology
The noun orthochromatic film comes from word parts ortho meaning 'correct' and chromatic meaning 'colour', but the easy image is a film that records blue and green light while ignoring 'red', so red things look very dark. That's why the name means film 'not sensitive to red light'.
