Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
102 words
A method of viewing a positive image of a film negative to determine if a print of it should be made and for making prints of acceptable images, comprising the steps of: a) developing an image on a film with developer solution; b) delivering the developed film to a bleach solution; c) removing the film from the bleach solution after a visible image has been formed; d) electrically capturing the visual image for viewing; e) finishing processing of the film to form a negative; and f) selectively making a print of a film negative if its captured visual image is considered acceptable.
Claim 2
Independent Claim
