BUT, can you definitively give the focal length and aperture of RLPhotos' three images?
Assuming little or no cropping, I'm guessing the dog was shot with a email@example.com or something along those lines, maybe shorter. The ratio of very large nose to tiny eyes means it was a relatively short lens to get that perspective. The apeture had to be smaller to create enough DOF to keep the nose and eyes both in focus since the dog has a long snout. It will be interesting to see what the actual setup was.
Nope all these images are shot @ f/2. The trick is proper technique to get what you want in focus.
If you can't tell between f/2.8 and f/2, bah you might as well shoot f/4 lenses because you won't be able to tell the difference either.
Then by all means educate us. Tell us how you were able to so distort the face of the dog and make such a massive nose and such small eyes so close together and yet maintain that DOF. We people you can't tell the difference and don't know proper technique want to know how to create these beady eyes and a huge nose peering thru a fog of blurred fur!
It's called a higher angle in which you tilt the camera down slight to move the plane of focus just enough to get both eyes in focus @ f/2.
Geez, do you guys actually go out and shoot? Its feels like I'm talking to some test chart shooter here.
