Could your friend be having you on? I only ask because (a) it's incredibly detailed and (b) you can get an app called Ghost Capture for the Blackberry, iphone and android as well as the ipad that does images like that and are impressive and show up clearly against any background. No offence intended and I hope you don't take that the wrong way but you can't be sure nowadays. It'll be cool if you could get other pictures with the child in different poses.

EDIT : Just read Evie's post haha I knew something was fishy about it

Very awesome picture. It does look like a little girl. She seems like she is warning him about something or letting him know that she is there. She actually looks like she is holding on to his pant leg. Wonderful picture great job
