Pale grey tree trunks side by side - 4K 影片檔

Low angle close-up shot of smooth, pale grey tree trunks featuring natural, eye-shaped markings and knots that resemble a cluster of watchful eyes. These eye-like patterns are natural scars created through a process called self-pruning, where the tree cuts off nutrient and sap flow to lower branches that no longer receive enough sunlight. When those unneeded branches die and fall off, the remaining stub heals and seals over with new bark, leaving behind an oval, eye-shaped scar.
