I am not really sure how to tag this other than a big #fail for the USPTO, or a huge Kudos for Amazon’s IP attorneys. In a patent simply called Studio arrangement Amazon took IP ownership on what we all call shooting against a seamless white backdrop.
The patent describes the arrangement of elements in the studio to make a product shot. it even details the F-stop, ISO value and focal length you need to use [bold text by me]:
a background comprising a white cyclorama; a front light source positioned in a longitudinal axis intersecting the background, the longitudinal axis further being substantially perpendicular to a surface of the white cyclorama; an image capture position located between the background and the front light source in the longitudinal axis, the image capture position comprising at least one image capture device equipped with an eighty-five millimeter lens, the at least one image capture device further configured with an ISO setting of about three hundred twenty and an f-stop value of about 5.6; …
Another part of the patent describes a table and some trivial lighting:
… an elevated platform positioned between the image capture position and the background in the longitudinal axis, the front light source being directed toward a subject on the elevated platform; a first rear light source aimed at the background and positioned between the elevated platform and the background in the longitudinal axis, the first rear light source positioned below a top surface of the elevated platform and oriented at an upward angle relative to a floor level; a second rear light source aimed at the background and positioned between the elevated platform and the background in the longitudinal axis, the second rear light source positioned above the top surface of the elevated platform and oriented at a downward angle relative to the floor level; a third rear light source aimed at the background and positioned in a lateral axis intersecting the elevated platform and being substantially perpendicular to the longitudinal axis, the third rear light source further positioned adjacent to a side of the elevated platform; and a fourth rear light source aimed at the background and positioned in the lateral axis adjacent to an opposing side of the elevated platform relative to the third rear light source; wherein a top surface of the elevated platform reflects light emanating from the background such that the elevated platform appears white and a rear edge of the elevated platform is substantially imperceptible to the image capture device; and the first rear light source, the second rear light source, the third rear light source, and the fourth rear light source comprise a combined intensity greater than the front light source according to about a 10:3 ratio.
If this all sounds too complex, the patent also describes the workflow in which you have to work in order to take the picture:
The patent number is 8,676,045B1 and you can read the entire boring text on USPTO, or just about any basic studio photography book.
Of course there is a reason for all that, and that is to take photos without any manipulation or green screen, as Amazon notes in the description of the patent:
Prior art solutions for achieving such a result for capturing images and/or video of objects set against a true white background include solutions that often involve some type of image retouching, post processing, “green screen” techniques, or other special effects and image and video manipulation to achieve the result of an object set against a true white background. Accordingly, as will be described herein, embodiments of the present disclosure provide a studio arrangement in which an object can be photographed and/or filmed, and the images and/or video captured by the camera achieve the effect noted above without any image manipulation due to the particular arrangements of the subject, camera, lighting and background.
Now, I am not a patent attorney, but it seems that 1. there is plenty of prior art on this and 2. there is absolutely no way to enforce it. I just hope that the lawyers at amazon are happy with their retainers.
