Well, professionals who take these types of photos care, outsiders don't care. Maybe you should at least skim through all the patent claims before saying it's just a camera in front of a white sheet.
I wasn't responding directly to the details of this patent application; rather, the notion that such a thing can be patented (and yes, I did read the claims). Presumably, if one can patent the white sheet with a specific lighting pattern, then previously one would have been able to patent just the white sheet, and that is ridiculous.
Consider it another way: I am a photographer using a white sheet as a backdrop. As I take a series of photos, thanks to digital photography I can immediately look at the results and move my lights around to remove shadows. At some point I happen to hit Amazon's patented light configuration, and I am now violating their patent. Dumb. Maybe they should also patent looking at the digital output and adjusting lighting? After all, that is part of the process for which they applied for the patent currently in question.
