To me, it looks like Photo 2 is taken from someone in the area where the astronaut is in Photo 1.
Math work:
In picture 2, The angle from a straight line, running through the base of the lander leg's bottom corner, to "object a" is ~ 27 degrees. From about the same spot (as well as I can draw and measure angles within gimp), the angle in picture 1 is only ~21 degrees. That leads me to believe that not only did the photographer move in, but also moved closer to the lander, which may explain the apparent change in angle
Edit: Angles to object B are also off by ~ 5 degrees
