How do you take HQ pics with your heads like this?

that isnt a hq pic it s just a filter u can easily do too. When u have the head do this on gimp
Filters ----> map ----> map on an object ---> change the general options from plan to sphere then change the cordinates of the head and the rotation too if u like it
this will be the result (i choose your head as example)


if u use photoshop i can t help u sorry xD
