Natural framing, or using something that may be otherwise seen as an obstacle can enhance your photography. The trick is having the eye to see it, or right position to capture it.
Seeing the twists and turns of the Great Wall of China I was able to frame it through a gate window.
Meanwhile the natural frame of the twisting roots and tree trunks covered this statue in Cambodia where only the face now peeks out. From guidebooks this phenomenon is described in detail and tells you to be on the look out for it. I was disappointed when I searched high and low and couldn’t find these elusive statues covered by nature. I assumed it was now lost under layers of time as it reclaimed its space. However, I was passing by a travel guide with a small group and they stopped in what appeared to be an unusual spot, nothing to see. I happened to overhear him point out the face peering out through the tree trunk. I looked and saw nothing. I looked closer and saw this tiny little face, something I assumed to be much larger. After all the large faces at Angkor Thom where massive, but this teeny face could be easily missed. What a great coincidence nature twisted and turned and allowed only the face to be perfectly framed and visible.
The more literal window frames inside the temples in Angkor Wat twisted and turned in such detail. More like spindles of wood than stone. I enjoyed looking through them and how they framed the windows into much more than just a square opening.
