Brought to our attention by Photography Bay, Amazon has patented a most ingenious invention: a completely revolutionary way to get a "true white" background on an image in-camera, without any post processing. We didn't understand how it was done, but now the US Patent Office has helped us all by posting this granted patent complete with plenty of diagrams supplied by Amazon's brilliant inventors.
In addition to the image above, we have been given a very precise and important order of operations, if you will, that must be followed to achieve this "true white" background, as shown in Figure 3. If you can't follow along, send a note and we'll see if a writer here can help you step-by-step:
First, however, to set up the lights, background, and object being photographed, one is to follow these diagrams:
While some photographers have been claiming to photograph objects using similar setups to create a "true white" background in camera, no one has yet patented this precise method, whereby one is to position the image capture device between the front light source and the object being photographed, use a table with a depth of four feet precisely elevated at 21 inches, and place the background approximately nine feet away from the object being photographed. Likewise, one can use similar ratios to place the object in any position within the studio or in relation to the background, so long as the object is positioned at a distance of about 4.5-5.5 times the height of the elevated table itself. One can even use both translucent and reflective pieces of Poly(methyl methacrylate), sometimes called "Plexiglass" by normal, non-patent-claiming people.
We haven't tried using these ratios before, nor have we used this amazing translucent and/or reflective material, Poly(methyl methacrylate). Truly amazing stuff.
Ok seriously though: this happened. Amazon owns this.
@strobist With the precedent now established by Amazon, I intend to file a patent on the technique for shooting at golden hour.
