You're probably violating copyright laws by copying the photo and posting it here! I saw the article about the photographer a week or so ago - can't remember where (I'll look for it). If it was my photo I'd tell you to take it down immediately.
Read:
"In simple terms, copyright for photographers means owning property. With ownership, you get certain exclusive rights to that property. For photographic copyrights, the ownership rights include:
(1) to reproduce the photograph;
(2) to prepare derivative works based upon the photograph;
(3) to distribute copies of the photograph to the public by sale or other transfer of ownership, or by rental, lease, or lending;
(4) to display the photograph publicly;" (Source: Photography and Copyright Law)
By posting that photo here you are making it easier for the photographer to lose control of his/her property.
You ask a good question, but a better way to ask it is to post a link to the article where you found the photo and show some respect for the work of the photographer... It's likely the original article has details the photographers technique.
dude, did you see the first post? theres a link to the article there, if you were to read the post, you probably would have noticed that?
