The invention is generally accomplished by providing a method of forming prints with colored borders. This is generally accomplished by exposing a color imaging substrate to colored light in a pattern at least partially encircling a central image. In a preferred form of the invention, the image is a color photographic image that is surrounded with a color image that is printed peripherally of the colored image on the same sheet of photographic paper. The colored border may suitably be a color such as gold, silver, or a color contrasting with the color print.

The invention relates to a photographic element comprising at least one absorber dye and at least one sensitizing dye wherein the peak sensitivity of said absorber dye and said sensitizing dye are similar. This provides improved perceptual red detail in regions of high red density in the negative image.

A method of setting the contrast of a color video picture generated on a screen of a video display device from a developed photographic film image to achieve a match in visual appearance between the color video picture and an illuminated reference print of the image involves the automatic and interactive development of contrast table output values for each of three different colors in shadow and highlight regions. A base contrast table, the input value and base output value of an inflection point, and default values of user selectable contrast settings for the shadow region and highlight region for each of the three colors is stored in a computer memory and used to generate initial output values of the contrast table. The stored base contrast table, and the input value and base output value of the inflection point, in conjunction with user selected new contrast settings are employed to automatically develop new contrast table output values. The contrast table output values are downloaded to respective look-up tables which modify input electrical signals to the video display device to affect the contrast of the color video picture presented on the screen of the display device. The contrast settings can be adjusted until a match in visual appearance of the video picture with an illuminated reference print is achieved. The ultimate contrast settings of this calibration operation can be used by the same equipment in a regular analyzing mode.

A technique for creating an image onto a photosensitive medium in a photoprinting process involves scanning a phototransparency for its densitometric information. Light from a lamp source is transmitted through an LCD pad onto a photosensitive medium to produce an image. The exposure of the image is regionally varied to achieve optimum results by activating individual LCD pixels to control the amount of light exposed to the photosensitive medium. A microprocessor calculates the activation pattern for the pixels based upon the densitometric information of the phototransparency.
