Expose for the sky (which means telling your camera to underexpose, as it'll try making the photo much brighter; in my case exposure compensating by -2.3EV), then everything on the ground turns way dark. This works out at ISO 100 in the photo above because the sun is not obstructed by any clouds. It is a direct source of light, bright and clear. It actually looked like that in real life, but my eyes were able to see the detail in those trees.
Stuff just turns dark when you do that kind of thing. It works during golden hour when the sun is low because all kinds of way long shadows are being cast everywhere on the ground. It would be harder to do in summer sunlight at noon because there's just bright light everywhere — you might be able to do it by standing in a shadow and having bright light in the background, though. But the trick is to expose for the sun and let the rest be underexposed.
