How these photos were taken: wide angle lens - 24mm, tiny aperture (f-11/f-16), a bright day, and manual focus and whatever ISO worked.
With manual focus, I was able to get the camera just inches, maybe just a couple inches, from the cats' faces, which gives kind of a big head/fun house look to my cats' cute little faces. With the tiny aperture and it being a bright day, I was able to still get sharpness - at least pretty sharp, despite the lack of focus from my lens.
This is fun to do to your own cats if they will put up with it, but don't try this on people! Their noses will look huge and they will hate you.
