Atmosphere is the secret weapon of realism. Air exists between the camera and the subject. The farther something is, the more atmosphere it has. That means: Less contrast. Less detail. More softness. More haze. When you add atmosphere correctly, your layers glue together. It also creates mood. Fog is not just an effect. Fog is depth.

Perspective is the camera angle. If your subject is shot from low angle, the environment must match. If your background is high angle, the subject must match. When angles clash, your brain rejects the composite. So check the horizon line. Where is the viewer standing? Are we looking up, straight, or down? Match that across elements. Perspective is not complicated. It’s honesty. Keep the camera consistent, and your scene becomes believable.

More assets does not mean better art. More assets usually means more problems. Every added element adds new light to match. New scale to fix. New color to balance. So we do the opposite. We build strong with less. A great scene can be made with three images. If the logic is correct. When your foundation is strong, effects become easy. Less assets. More intention.
