Abstract

Disclosed is a method of producing color-comparable photographs with which a prosthetic fabrication artist can determine whether photographs taken of an amputee'"'"'s extremity are color-true and whether recorded color selections, matching pre-designated areas of the extremity, were accurately chosen. A prosthetic technician, or another skilled in the art, takes color photographs of an amputee'"'"'s extremity on a duplicate copy of a colored background which has a neutral colored central area and a perimeter band of various human fleshtone or skin colors. The technician matches certain colors in the perimeter color-band to pre-designated areas of the extremity and records them on a color selection diagram. The photographs and color selection diagram are forwarded to the fabricating artist who uses them to determine the proper coloration of a prosthetic restoration by comparing the colored background shown in the photograph with a second duplicate copy of the colored background in the possession of the fabricating artist.

Claims

1. A method for producing color-comparable photographs which include the view of recorded, visually selected skin color matches of an amputee'"'"'s uninjured limb extremity for the substantial identical coloration of an anatomically correct prosthetic restoration for the amputee'"'"'s injured limb extremity in the absence of the amputee, comprising the steps of:

producing a colored photography background on a flat surface including a neutral colored central area such as gray, and a multi-colored outer band around the perimeter of the flat surface containing a variety of individually numbered human skin fleshtone colors ranging from light skin colors to dark skin colors;

producing duplicate copies of the colored photography background;

delivering a first duplicate copy of the colored photography background to at least one cooperating technician responsible for photographing the amputee'"'"'s limb extremity in a first location;

visually selecting individually numbered skin colors from the perimeter multi-colored band which closely match pre-designated areas on the amputee'"'"'s uninjured limb extremity;

recording the color selections so that each color number corresponds to the pre-designated areas on the amputee'"'"'s uninjured limb extremity;

placing the amputee'"'"'s uninjured limb extremity atop the surface of the first duplicate copy of the colored background adjacent to the perimeter band of skin colors;

photographing the uninjured limb extremity while it rests on the surface of the first duplicate copy of the colored background;

delivering the developed photographs of the limb extremity shown atop the first duplicate copy of the colored background along with the recorded color selection numbers to a fabricating artist in a second location;

comparing the photographs of the uninjured limb extremity as shown atop the first duplicate copy of the colored background to a second duplicate copy of the colored background;

comparing the recorded color selections as they appear on the second duplicate copy of the colored background to the corresponding pre-designated areas on the uninjured limb extremity shown in the photograph;

utilizing the comparison of the first duplicate copy of the colored background shown in the photograph with the second duplicate copy of the colored background as a means to determine the color and/or shade accuracy of the photographs; and

utilizing the comparison of the recorded color selections as they appear on the second duplicate copy of the colored background to the corresponding pre-designated areas on the uninjured limb extremity shown in the photographs as a means to determine the correct coloration of an anatomically correct prosthetic limb restoration device for attachment to an amputee'"'"'s injured limb extremity.

2. The method of claim 1 wherein the colored background includes a color-band with medium shades of the three basic primary colors;

red, blue and yellow.

3. The method of claim 1 wherein the colored background is printed on a surface with a matte finish.

4. The method of claim 1 further including rotating the colored background for a series of photographs with the limb extremity at rest on the neutral colored central area adjacent to different multi-colored perimeter bands of the colored background in each photograph.

5. The method of claim 1 further including the addition of colored light while taking the photograph for the purpose of altering the color of the developed photograph.

6. The method of claim 1 further including the addition of colored light while viewing the developed photograph for the purpose of adjusting the perceived color of the first duplicate copy of the colored background shown in the photograph to match the second duplicate copy of the colored background.

7. The colored photography background according to claim 1 for the purpose of producing color-comparable photographs and making a record of visually matched human skin fleshtone colors to be used in prosthetic limb extremity restoration fabrication.
