I find this rock fascinating. How did it break? Why is there a round rock within a round rock? Where is the missing piece? The photo was shot with the native #iPhone5 camera app and the #monochrome conversion was done with #Snapseed. The level of control that Snapseed gives is awesome. Note the detail in the shadow side of the rock, this area went completely black in some of the other apps that I tried. #discoverpressgram #texture #shadowdetail
