Question

Answer the following question in 3-4 complete sentences.

Who invented negative film? Explain how negative film is used in photography

Answer 1

Negative film was invented by Henry Fox Talbot. Negative film is a roll of film with a gel or lotion over it, with light-sensitive silver-nitrate crystals in the emulsion. When exposed to light, it creates a negative image. When we look at a negative image on film, all the light colors are dark and all the dark colors are light. This image can be duplicated or enlarged onto photography paper that is light-sensitive. Because the paper is light-sensitive, the image appears as a positive image.

Answer 2

Henry William Fox Talbot invented the negative film.

When negative film is exposed to light, it creates a negative image.

That negative image shows that all the light colors are dark and all the dark colors are light.

This image can then be duplicated or enlarged onto photography paper that is light-sensitive and since the paper is light-sensitive, the image appears as a positive image.
