This is the Apollo 11 photo designated AS11-40-5925, a popular photo with moon landing deniers.
The camera is facing generally north-north-west. The sun is low in the sky, about 10º-15º above the horizon on the east. The silver pole in the upper right of the photograph is pretty much straight up, casting shadow in the expected direction. The landing leg in the upper center is tilted away from the sun angle somewhat, not enough to significantly change the direction of the shadow. This is all really straightforward.
The confusing part is the probe in the right foreground. These probes hang down from the footpads of the lander and illuminate a light in the cabin when the lander is about 2 meters above the surface. When the pad comes down to the surface, the probes are bent away in unpredictable directions depending on which way the LM is drifting at touchdown.
In this image, the probe is bent backwards, generally toward east-north-east. The probe extends out of frame to the right; it's about twice as long as the diameter of the footpad. Since it's mostly pointing towards the sun, the shadow is severely foreshortened -- the shadow is cast nearly down the length of the probe.
