orthochromatic

adjective ˌɔːθəʊkrəˈmatɪkˌɔrθoʊkrəˈmædɪk

Often contrasted with panchromatic
Example sentencesExamples
- Orthochromatic photography refers to an emulsion that is sensitive to only blue and green light, and thus can be processed with a red safelight.
- As plates and films became more sensitive (orthochromatic emulsions are sensitive to green as well as blue light), ruby safelight filters became necessary, but the old manipulation techniques could still be utilized.
- I use traditional panchromatic films for the interpositive and an orthochromatic film for the final enlarged negative.
