What to inspect
Nature scenes hide errors inside complex texture. Look past dramatic color and inspect branching patterns, water physics, repeated rocks, horizon geometry, cloud lighting, and fine vegetation.
01
Check whether reflections, ripples, waterfalls, and shorelines obey consistent water physics.
02
Look for copied clusters of leaves, rocks, flowers, or clouds and branches that merge unnaturally.
03
Compare the direction of sunlight across the sky, terrain, shadows, and reflected surfaces.
