Center of the image is zoomed in while edges and corners are zoomed out. How to apply this effect? Which application to use?

    The "application" is an understanding of perspective and how it is influenced by camera subject distance. – Michael C Aug 19 '16 at 05:28

    Why do you think the center of the image is zoomed in? It is not. This is a wide-angle photo taken with a fisheye lens. This is what allows such a wide angle to be captured. – osullic Aug 19 '16 at 08:59
  • "fisheye lens" what I was looking for. I will select it if you post it as an answer – Ned Aug 19 '16 at 15:27

    Please use a descriptive title. Can you imagine how many did questions could share this one? – mattdm Aug 19 '16 at 22:07

There is no special effect or filter recognizable.

The human eye has about f = 45-50 mm; wide-angle lenses (f < 45 mm) have the result that objects very near to the camera look unproportionally larger than they look to the naked eye; the smaller f gets, the more obvious the distortion. Note that tele lenses (f > 50 mm) have the opposite result; everything seems to be about equally distant, 'flattened out'.

This shot is probably done with a 22 or 18 mm, and if you go even further down, you get such a strong and obvious distortion that it has its own name, 'fisheye'.
