This invention relates to cameras designed for single or limited use. It more particularly relates to cameras that are intended for one use, after which they are recycled, subsequent to removal of the film for development and printing or scanning. The camera and film combinations provide exceptionally sharp images.
Claims40
A camera comprising:
- a film container;
- a color negative film contained in said film container which has a green density MTF value of above 1.25 for a spatial frequency in the range of 15 to 25 lines/mm after imagewise exposure and processing;
- a taking lens mounted on said film container to expose said film, said taking lens having a green light MTF value of less than about 0.8 at a spatial frequency of 20 lines/mm;
- said color negative film comprising a red light sensitive color record, a green light sensitive color record and a blue light sensitive color record, and having a photographic sensitivity of greater than ISO 100.

A camera comprising:
- a film container;
- a color negative film contained in said film container which has a green density MTF value of above 1.15 for a spatial frequency in the range of 10 to 30 lines per mm after imagewise exposure and processing;
- a taking lens mounted on said film container to expose said film, said taking lens having a green light MTF value of less than about 0.8 at a spatial frequency of 20 lines per mm;
- said color negative film comprising a red light sensitive color record, a green light sensitive color record and a blue light sensitive color record, and having a photographic sensitivity of greater than ISO 125 and an exposure latitude greater than 2.1 log E.
