Well, not really a trick. But the setting sun does some very selective lighting, and picking out this curve of branch seemed rather peculiar. Another shot, I think, where scale is a bit ambiguous. The lights and darks are even more vivid on the screen than they were in “real life,” and I love the golden loop backed up against the gray above and the reddish bark chips below. Feels almost like it’s about to burst into flame — like the sunset.
Everything is ambiguous about the shot. Quite nice.
The palette really appeals to me. It can be difficult to capture that special cast that the sunset has, but you have done it here. The golden loop looks rather glyph-like — so you!
