ABSTRACT:

FIELD OF THE INVENTION
This invention relates to photography and in particular to a filter for modifying color rendition.
BACKGROUND OF THE INVENTION
It is usual to put filters in front of camera lenses to modify color rendition. The Patents FR 2 205 210 and FR 2 441 186 describe systems for holding filters in front of camera lenses. However, cameras using such filters are single lens reflex cameras.
It is the object of the invention to provide this technique to users of less cumbersome cameras available for the general public Such as single use cameras that are factory loaded.
SUMMARY OF THE INVENTION
This object of the invention is achieved with an adaptable special effects filter for cameras with a body fitted with a separate lens and viewfinder, which is characterized by a transparent support sliding on the camera body, between at least two positions, the filter being fitted with at least one zone capable of covering the lens and the viewfinder of the camera, when it is in at least one of the positions thereof, so that similar light transmission characteristics are arranged opposite the camera's lens and viewfinder.
These and other aspects, objects, features and advantages of the present invention will be more clearly understood and appreciated from a review of the following detailed description of the preferred embodiments and appended claims and by reference to the accompanying drawings.
