Which description accurately defines Depth of Field in post-processing?

Depth of Field in post-processing accurately refers to the simulation of camera lens focus properties. This technique allows certain objects within the scene to be in sharp focus while others gradually blur, mimicking how real-world cameras operate. It is commonly used to direct the viewer's attention toward specific elements in the frame, creating a more cinematic feel and enhancing the overall visual storytelling.

The concept functions by defining a focal plane, where objects are rendered crisp, while those in front of or behind this plane are blurred. This effect effectively adds a sense of depth to the scene, helping to convey distance and spatial relationships among objects. With appropriate adjustments, Depth of Field can create a more realistic perspective, enriching the player's visual experience.

The other options touch on different aspects of image processing in Unity but do not relate to Depth of Field. For instance, controlling brightness, enhancing color saturation, and adjusting contrast levels are distinct processes that involve altering the image's exposure and color properties, not the focus characteristics that Depth of Field specifically addresses.
