Why because he's not shooting porn ? He's just posting comparisons - actual subject matter is irrelevant for the most past.
Well, in truth, the subjects are quite bland. You could say the same of
test targets such as the one below,
but in this case, a reviewer can look at the skeins of embroidery floss and say-- wow, look at that detail, that color rendering-- or not.He can look at the vinegar bottle, and distinguish a crisp rendering from a morass of chroma noise. He can distinguish between poorly performing cameras, and cameras worth buying. But as far as showing off the creative options that a user has at his disposal, there's nothing. It's a f/8 shot, on a tripod, possibly manually focused..
So, what are you trying to do when you take the shot of the wire fence? Test the color? The detail associated with the rusty bolt and the scuff marks around it? The contrast between the bits in focus and the bits that are out of focus? The quality of the bokeh?
How about the chainsaw? What's more important? A blurry background? The weathering on the handle?
I suppose that the rose is a "classic" blurred background shot, but if I was taking it, I'd probably look to bring out the soft texture of the petals.
A DLSR allows a photographer a wide range of possibilities in taking a shot. A camera phone doesn't. Perhaps if you let the computers decide, the more recent chip will have a better grasp of what makes for a great picture. But if you let a human brain decide, the DSLR offers that brain more creative control.
