How do i do that? using what apps
You need the thinest sting you can find.A fishing line can do it.Tie it to both his legs and arms, and balance.
Hmm...The more I look at it the more photoshoped it looks like he had a green screen setup behind these figures.I got it.
1- He got sting and wire it up to the figures.
2-He put a green screen behind the figures.
3-He Photoshoped the Stings out of the picture.
4-He Applyed a background of a ring.(Ring= boxing ring)
5-Gave everthing a slight blur.
You can turn green screen into something else with After Effects.Here's a tutorial: http/nofilmschool.com/2013/01/4-tutorials-improve-green-screen-skills
