Photogram is the word in Lyra's world for "photograph".
Lord Asriel would insert a slide into the frame of the Projecting lantern, a photogram appears on the linen screen. A photogram is the picture that was taken. One photogram was taken with a standard silver nitrate emulsion. A photogram that shows Dust was taken with a special emulsion. A photogram of the Aurora, also known as Northern Lights taken with the special emulsion showed a city in another world
Quotation In The Book
| "That photogram was taken with a standard silver nitrate emulsion," Lord Asriel said. "I'd like you to look at another one, taken from the same spot only a minute later, with a new specially prepared emulsion."
- "He lifted out the first slide and dropped another into the frame. This was much darker; it was as if the moonlight had been filtered out." - "It registered as light on the plate because particles of Dust affect this emulsion as photons effect silver nitrate emulsion." | |||
