Supercamouflagalistic

I can't even begin to imagine how much planning it took for Desiree Palmen to make one of these camouflage pictures. I mean, did she have to decide on a place before hand and then go home and paint some clothes to match the location exactly or did she make her subject stand in the location while she painted their clothes on the spot? Or am I just dumb and she made these pictures in Photoshop? Yeah, I just thought of that right now.
