Advantages of Using HDR Images

Realistic Lighting and Shadows

HDR Images can be used as a light source to illuminate a CG scene. These images have higher range of luminance levels, therefore they give accurate lighting and cast believable shadows.

Reflections

Metallic and glossy materials created in 3D, need something to reflect. Using panoramic HDR Images as environment map, glossy materials gets a world around them to reflect.

Fast Setup

Instead of setting up lights individually and manually, you can achieve better and realistic results by lighting the entire scene with help of a single HDR image.
