Photography Stack Exchange is a question and answer site for professional, enthusiast and amateur photographers. It's 100% free, no registration required.

Amazon has just been granted a patent on the method for using:

  • A white seamless background
  • An elevated platform
  • Rear-facing lights

...in order to make the entire background and platform disappear without the use of green-screen techniques.

That's a fine approach, but it certainly does not look patent-worthy to me. If we can find examples of this technique being used before November 2011 ("prior art"), then we can help invalidate the patent, and possibly prevent photographers from being sued.

I have various links regarding the patent:

I think this issue is worth the attention of the Photo Stack Exchange community.

As any answers should be posted on Ask Patents, I reckon this question could be closed but not deleted here (until the Ask Patents question gets an accepted answer, at the very least) - I obviously don't want to wave my moderator stick, if the wider community doesn't agree with me, which is why this comment exists :) –  Rowland Shaw May 7 at 9:44

I think its relevant. How many of the people on this site have any reason to peruse the Ask Patents site? If anything having this posted here makes them even more aware of the issue so that they could go there and provide their input. While being specific and probably non-enforceable, i think this is a very important issue for photographers. –  ecathell May 8 at 20:45

@ecathell: That's exactly why I posted it here. And if nothing else, we'll get a bit of photography history. –  Craig Walker May 8 at 22:08

I can't say when it was first used, but I do have a book here from 1985 that describes how to get a completely white background (give it 2 stops more light than the subject). –  Bart van Ingen Schenau Jun 18 at 14:02
