A picture released by North Korea's official Korean Central News Agency (KCNA) on March 26, 2013 appears to show evidence of digital manipulation, specifically the cloning of at least two hovercraft, to make it appear as if more vehicles were involved in a recent military exercise. The original caption: This picture released by North Korea's official Korean Central News Agency on March 26, 2013 and taken on March 25, 2013 shows the landing and anti-landing drills of KPA Large Combined Units 324 and 287 and KPA Navy Combined Unit 597 at an undisclosed location on North Korea's east coast. #

The hovercraft depicted inside the boxes in this image released by KCNA appear to be digital clones of each other, most evident in the blue boxes, where the leftmost hovercraft has apparently been copied, pasted and touched up to become a separate hovercraft at right. The leftmost vehicle, circled, does not appear to be a clone of any other craft in this photo, but its soft edges, lack of a visible wake, and color oddities make the image suspect. #

A three-step animation sequence, showing how the image of the hovercraft at left appeared to be manipulated digitally. 1) The section is selected, and copied. 2) The selection is moved toward the new placement. 3) Once placed, the image is sized up to simulate perspective shift, then the hard edges are softly erased, so it will blend in. #

A second photo released by KCNA reportedly at the same location, on the same day. No manipulation is apparent, this image is just for reference, as it's the only other photograph I could locate that was taken at the same time.
