Abstract
Abstract Image-enhancement is achieved by the use of instant color film. Such film has a predetermined development time, and after exposure of one print, it is developed and then development is stopped, usually before the normal development time. Another exposure is made on a second film of the same type, such as another print from the same film pack, and development is stopped after a different time. At least one of the prints is developed for a time less than the normal development time of the film. The resulting prints are of different colors, and are viewed together.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
199 words
A method of enhancing the understanding of the information provided by the image of an object such as an image displayed on an oscilloscope display comprising: (a) photographing the object with instant color photographic film containing materials which exhibit different colors upon exposure and subsequent development by developer material associated with the film, the film being fully developed after a predetermined time; (b) initiating development of said film; (c) stopping development of said film after a predetermined time following initiation of development; (d) photographing the object with a second instant color photographic film as in step (a); (e) initiating development of said second instant film; (f) stopping the development of said second film after a predetermined time following initiation of development of said second instant film, said time of development of said second instant film being different from the time of development of said first instant film sufficient to provide an observable color distinction between said two films, and at least one of said times of development being less than the full development time of said film; and (g) viewing said films to thereby obtain enhancement of the understanding of the information provided by the image of said object.
Claim 2
Independent Claim
199 words
A method of enhancing the understanding of the information provided by the image of an object such as an image displayed on an oscilloscope display comprising: (a) photographing the object with instant color photographic film containing materials which exhibit different colors upon exposure and subsequent development by developer material associated with the film, the film being fully developed after a predetermined time; (b) initiating development of said film; (c) stopping development of said film after a predetermined time following initiation of development; (d) photographing the object with a second instant color photographic film as in step (a); (e) initiating development of said second instant film; (f) stopping the development of said second film after a predetermined time following initiation of development of said second instant film, said time of development of said second instant film being different from the time of development of said first instant film sufficient to provide an observable color distinction between said two films, and at least one of said times of development being less than the full development time of said film; and (g) viewing said films to thereby obtain enhancement of the understanding of the information provided by the image of said object.
Claim 3
Dependent Claim
13 words
The method according to claim 1, comprising the photographing of an oscilloscope display.
Claim 4
Dependent Claim
12 words
The method of claim 1, comprising the photographing of an x-ray film.
Claim 5
Dependent Claim
11 words
The method of claim 1, comprising photographing a continuous tone image.
Claim 6
Dependent Claim
50 words
The method according to claim 1, and further comprising photographing the object with at least one additional photographic film as in step (a), and stopping development thereof at a different time than of the other said films, and at a time less than the full development time of said film.
Claim 7
Independent Claim
146 words
The method of enhancing the understanding of the information provided by the image of a continuous tone object comprising exposing the image onto multiple instant color photographic films which contain (a) materials responsive to different colors, and (b) means carried by a separate sheet for fully developing said materials after a predetermined period of time, and which sheet is detachable to stop development, separating a said sheet from one said exposed film of said object at a different time than a said sheet from a different exposed film of said object, said time difference being sufficient to provide an observable color distinction between said two films, at least one of said separating steps being effected in a lesser time than required for full development of said film, so that said films provide images of said continuous tone object in observably different colors, and viewing said films.
Claim 8
Independent Claim
146 words
The method of enhancing the understanding of the information provided by the image of a continuous tone object comprising exposing the image onto multiple instant color photographic films which contain (a) materials responsive to different colors, and (b) means carried by a separate sheet for fully developing said materials after a predetermined period of time, and which sheet is detachable to stop development, separating a said sheet from one said exposed film of said object at a different time than a said sheet from a different exposed film of said object, said time difference being sufficient to provide an observable color distinction between said two films, at least one of said separating steps being effected in a lesser time than required for full development of said film, so that said films provide images of said continuous tone object in observably different colors, and viewing said films.
Claim 9
Dependent Claim
14 words
The method of claim 6, and further comprising exposing an oscilloscope to said films.
Claim 10
Dependent Claim
14 words
The method of claim 6, and further comprising exposing an x-ray to said films.
Claim 11
Dependent Claim
17 words
The method of claim 6, wherein at least two said films have said image exposed onto them.
Claim 12
Dependent Claim
49 words
The method of claim 6, wherein more than two said films have said image exposed onto them, and at least two said films have the said sheet thereof separated therefrom to stop development at different times which are less than the time required for full development of said film.
