Double Image

Been playing with this little app called Double Photo with my Android mobile.  Not much to choose from at the present moment.  Only four combinations - Screen, Multiple, Lighten & Darken.  If want more, then need to purchase a pro version. Of course, a much admirable result can be achieved if using a digital SLR camera.

After taking the pictures, I opened them up with another app - PowerCam and applied some enhancements to make them interesting.
