In photography, the focal length of a camera divided by the diameter of its aperture. Knowing the f/stop, a light meter can measure the light on the subject, and calculate the exposure time.
narrative painting
A painting or sculpture whose composition, colors, and subject are selected to tell a story.
Example: Trajan's Column, Rome, Italy, 113
nave
The part of a church between the entrance and the choir. It is usually in the western end of the building. Generally it is where seats are placed for worshippers.
Example: Notre Dame Cathedral, Paris, France, begun 1163
non figurative
An aspect of modern art in which pieces of art contain no recognizable figures or objects, as opposed to figurative art.

non-photo
A very pale blue that is invisible to a camera or photocopier. A non-photo pen or pencil may be used to make notes on an original: paper may be printed with a non-photo blue grid to allow for easy line-up. In either case, as copiers become more sensitive, you should advise your customer to test these products first.
