receiving a height of the object at a user interface physical incorporated into the platform and in communication with a processor; and adjusting, via the processor, a magnification of a top surface of said object in said digital image based on the height of said object. ### Claim 2 (depends on 1) The method of claim 1, wherein adjusting a magnification of a top surface of said object in said digital image based on a height of said object includes reducing said top surface by a magnification factor M determined by M=((hp−ho)/hp)(100%), where hp is a distance between said camera and said platform supporting said object and ho is said height of said object. ### Claim 3 (depends on 1) The method of claim 1, wherein adjusting a magnification of a top surface of said object in said digital image based on a height of said object includes resizing said image such that said top surface appears to be spaced as far away from said camera as said platform. ### Claim 4 (depends on 1) The method of claim 1, further comprising taking said digital image and selecting a magnification correction mode prior to taking said digital image. ### Claim 5 (depends on 1) The method of claim 1, further comprising correcting said digital image for lens distortion prior to adjusting said magnification. ### Claim 6 (depends on 1) The method of claim 1, further comprising receiving the height of the object at the user interface as user input. ### Claim 7 (depends on 1) The method of claim 1, further comprising receiving the height of the object automatically via the processor. ### Claim 8 (depends on 1) The method of claim 1, further comprising requesting the height from a user via the user interface. ### Claim 9 A system for adjusting digital images for parallax, comprising: a digital camera secured to a platform; a processor in communication with said digital camera; said processor programmed to: receive a digital image of an object on said platform; receive a height of the object at a user interface physically incorporated into the platform and in communication with the processor; and reduce a magnification of said digital image based on the height of the object such that a top surface of said object in said digital image appears as though said top surface is level with said platform. ### Claim 10 (depends on 9) The system of claim 9, wherein said processor programmed to reduce said magnification of said digital image includes adjusting said magnification of said top surface in said image based on a height (109) of said object by reducing said top surface by a magnification factor M determined by M=((hp−ho)/hp)(100%), where hp is a distance between said camera and said platform and ho is said height of said object. ### Claim 11 (depends on 9) The system of claim 9, wherein said processor is programmed to receive a height of said object from a user interface in communication with said processor. ### Claim 12 (depends on 9) The system of claim 9, wherein said processor is programmed to correct said digital image for lens distortion prior to resizing said digital image. ### Claim 13 (depends on 9) The system of claim 9, wherein said processor is programmed to instruct that said digital image be printed. ### Claim 14 (depends on 9) The system of claim 9, further comprising a default height repository to retrieve a height value for a default height of the object. ### Claim 15 A non-transitory computer-readable medium storing instructions executable by the computer to: instruct that a digital image of an object on a platform be taken with a camera that is spaced apart from said platform by a predetermined distance; receive said digital image; receive a height of the object at a user interface physically incorporated into the platform and in communication with the processor; and adjust said digital image with a magnification factor based on the height of said object. ### Claim 16 (depends on 15) The medium of claim 15, further comprising the instructions executable to determine said height based on an input into a user interface. ### Claim 17 (depends on 15) The medium of claim 15, further comprising the instructions executable to determine a default height in an absence of an input into a user interface. ### Claim 18 (depends on 15) The medium of claim 15, further comprising the instructions executable to correct said digital image for lens distortion prior to adjusting said digital image with said magnification factor.
