Can someone with some method patent experience tell me how this would be enforceable? Unless someone was in your studio, and saw/videoed/photographed your setup, how could Amazon claim that their “method” was infringed upon?
“You’ve got no shadows! …you must have used our patented methodology.”
IMHO, if you are a studio shooter and you can’t suss out how to effectively remove shadows from your background, you may want to consider a new vocation. So, what am I missing here? Granted, I do not live in the US, but I am a tad concerned that this madness could “leak out”.
Or is this just because North America has too many lawyers and this is simply job creation?

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
