Unless you fancy yourself an expert on product photography, is it really necessary to talk down about other people on the subject?
Do you understand what the photographer is trying to do in this video-- not just "he's trying to get rid of reflections", but how each bit of foamboard improves the shot?
I don't. It looks like it requires a lot of specialized equipment, technique, and craft.
And, yet, the end result looks like it could sell the product. When I see the drill, it doesn't scream "BUY ME"-- and I don't have the artistic experience to understand what sort of improvements can bring it to that next level.
Conversely, when some photography lesson shows a portrait, I can judge the photograph-- and the technique, and the equipment. I know where to find the flaws and the artistry.
