Name for a standard laboratory test film usually incorporating a face and a greyscale; used for printer line-up and for colour standardisation in still image photography.
Chinagirls are used to adjust electronic analysers and printers.
They are on negative and positive material and provide subjective and objective colour and gray scale patches. These patches can be read on densitometers to confirm the process.
