I claim: 1. An apparatus for determining the attributes of a digital image, comprising: a target device for inclusion in a digital image, the target device being operative to enable the discovery of attributes of the digital image, the target device including: a disc portion, the disc portion including concentric, contrasting rings; and a three-dimensional shaped portion centrally located on the disc portion. 2. The apparatus of claim 1, wherein the concentric, contrasting rings are color-coded to increase visibility of the apparatus within the digital image. 3. The apparatus of claim 2, wherein the concentric rings are color patterns which contrast with a surrounding environment and are identifiable by digital imaging software. 4. The apparatus of claim 2, wherein the disc portion further includes an outer border of colored material that contrasts with the concentric, contrasting rings such that the outer border provides a visual separation between the concentric, contrasting rings and environmental surroundings included in the digital image. 5. The apparatus of claim 4, wherein the environmental surroundings comprise at least one of a background and a subject that are captured in the image. 6. The apparatus of claim 2, wherein the concentric, contrasting rings include a ring of a neutral light color density that enables a measurement of light color and perceived temperature associated with the digital image. 7. The apparatus of claim 2, wherein the three-dimensional shaped portion enables a measurement of at least one of light direction, light diffusion, and light ambiance associated with the digital image. 8. The apparatus of claim 1, further comprising graphical patterns on the surface of at least one of the disc portion and the three-dimensional shaped portion, such that the relative size of the apparatus is determined by examining the graphical patterns. 9. The apparatus of claim 1, wherein the three-dimensional shaped portion includes at least one of a substantially spherical, elliptical, and faceted surface. 10. The apparatus of claim 1, wherein the disc is one of substantially circular, and substantially square in shape. 11. The apparatus of claim 1, further comprising a surface arranged to reflect spectral light rays. 12. The apparatus of claim 1, wherein the disc portion is symmetric from horizontal views of equal height such tat further orientation of the apparatus is avoided when the apparatus is placed on a level surface and digital images are captured from different points of reference. 13. The apparatus of claim 1, further comprising an elevating device to raise the apparatus a predetermined height. 14. A method for determining attributes of a digital image, comprising: locating a target device within the digital image, wherein the target device includes a disc portion and a three-dimensional shaped portion; measuring attributes associated with the target device; and automatically associating the attributes of the target device with the digital image such that the digital image assigned with the attributes. 15. The method of claim 14, wherein associating the attributes further comprises storing the attributes in a database in association with the digital image. 16. The method of claim 14, wherein associating the attributes further comprises embedding the attributes into the digital image. 17. The method of claim 14, wherein locating the target device further comprises scanning the digital image for a high color luminescence value emanating from the target device such that a color luminance curve may be generated, and examining the color luminance curve to determine the distance of the target device from an edge of the digital image. 18. The method of claim 14, wherein locating the target device further comprises initiating at least one of particle analysis and color space analysis to determine the position of the target device. 19. The method of claim 14, wherein locating the target device further comprises scanning the digital image for a geometric shape corresponding to the target device. 20. The method of claim 14, wherein measuring attributes associated with the target device further comprises measuring ground surface angle value associated with the target device. 21. The method of claim 14, wherein measuring attributes associated with the target device further comprises measuring the reflective illumination properties associated with the target device. 22. The method of claim 21, wherein the attributes associated with the target device comprise light direction. 23. The method of claim 21, wherein the attributes associated with the target device comprise a measure of light diffusion. 24. The method of claim 21, wherein the attributes associated with the target device comprise a measure of ambient light. 25. The method of claim 14, wherein measuring attributes associated with the target device further comprises calculating a relative dimensional scale of the digital image based on a predetermined scale of the target device. 26. The method of claim 14, wherein measuring attributes associated with the target device further comprises measuring apparent light color temperature by measuring a color hue value of the target device and comparing the color hue value to a neutral color standard. 27. The method of claim 14, wherein measuring attributes associated with the target device further comprises measuring a vanishing point perspective factor that corresponds to a ratio that results from a comparison of distance between two separate sets of points, wherein the first set of points is located at a front side of the target device and the second set of points is located at a back side of the target device. 28. A computer-readable medium having stored thereon a data structure, comprising: data stored in an image region that include digital information defining an image including a target device, wherein the target device includes a disc portion and a three-dimensional shaped portion; and an index region that includes attribute information describing attribute of the target device in the image. 29. An apparatus for indexing a digital image with visual attributes, comprising: a means for locating a target device within a digital image, wherein the target device includes a disc portion and a three-dimensional shaped portion; a means for measuring visual attributes associated wit the target device by examining at least one of the disc portion and the three-dimensional shaped portion; and a means for associating the visual attributes of the target device with the digital image, such that the digital image is indexed wit the visual attributes.
