In post-processing, what does it mean to "simulate physical camera properties"?

Simulating physical camera properties in post-processing refers to the practice of mimicking how real-world cameras operate in terms of image capture and rendering. This includes adjusting aspects like aperture, exposure, focal length, and depth of field, all of which affect how images are perceived visually.

By emulating these mechanics, game developers can achieve more realistic and visually appealing results. For instance, using a shallow depth of field can replicate the blurry background effect often seen in photography, drawing focus to the subject. Similarly, adjusting exposure can simulate the way cameras capture images in different lighting conditions, allowing for enhanced realism in the game’s visual presentation.

This concept is crucial in post-processing because it helps integrate the game's visuals into a cohesive and believable environment, making the experience more immersive for players.
