Used Photoshop CS5 Extended (no negative comments please)
My opinion and few of my friends is that the change makes it look cooler as if the picture was made like that.
How to do this effect (Note: does NOT work on every picture!)
1. Open up the picture you would like to edit
2. Roughly outline the object (leave some space away from the body, will explain why in the next few steps)
3. Press SHIFT + F5
4. For "Use" select Content-Aware
5. for Blending select Mode - Screen and Opacity 100% press OK
6. Once loaded, you will see the weird looking patches of light around the guy (there is a reason why I told you to leave some space)
7. Click the "Spot Healing Brush Tool" and carefully try to highlight those spots (If does not work, select the Lasso tool and do "Content-Aware" and for mode "Normal")
8. Finalize the picture, save as and you have your own "Cloak-Style" photoshop!
Feel free to make a video tutorial! (Link me if you do!)
