How do you get a soft drop shadow on the sky, if not Photoshop? How do you get a perfectly squared billboard in a photo taken from the ground? Perspective is a thing.
There may be a real billboard like this out there somewhere, but this picture is BS.
But the pixeling should be the same throughout the entire image. That has to do with the image resolution, not the depth of field. The soft edges of the out-of-focus crowd should still have pixelized edges, even with the blurred edges.
Gregory (Scotland Yard detective): “Is there any other point to which you would wish to draw my attention?”
Sherlock Holmes: “To the curious incident of the dog in the night-time.”
Gregory: “The dog did nothing in the night-time.”
Sherlock Holmes: “That was the curious incident.”
Now that right there is thinkin’ outside the box.
