ABSTRACT:

FIELD OF THE INVENTION
The invention relates to photography and to electronic-film cameras and more particularly relates to a verifying camera having a demonstration mode and a related method.
BACKGROUND OF THE INVENTION
It has been a common practice in selling cameras to let potential customers handle the cameras. This has sometimes included “dry-firing” the cameras, that is, shooting pictures without film. Verifying cameras are a type of hybrid film-electronic camera in which the user has an opportunity to check captured film images immediately after capture using a concurrently recorded electronic image.
It would thus be desirable to provide an improved verifying camera and method in which features of the camera can be demonstrated without film.
SUMMARY OF THE INVENTION
The invention is defined by the claims. The invention, in its broader aspects, provides a method for demonstrating a film-unloaded verifying camera in response to shutter button actuation. In the method, an electronic image is captured and the electronic image is shown to the user along with an indicator that film is not loaded. The film shutter can optionally be fired to provide a more complete experience of camera use. A camera provides these features.
It is an advantageous effect of at least some of the embodiments of the invention that an improved verifying camera and method in which features of the camera can be demonstrated without film.
