What does HDRI technology aim to replicate?

HDRI (High Dynamic Range Imaging) technology aims to replicate a dynamic range similar to human vision. This is essential for capturing scenes with both very bright and very dark elements, allowing for a more balanced and realistic representation of what the human eye can perceive. By combining multiple exposures of the same scene, HDRI retains detail in highlights and shadows, creating images that are more nuanced and closer to our natural perceptions.

Other options, while relevant to photography, do not accurately capture the primary goal of HDRI. For instance, although natural sunlight in portraits and a wider spectrum of visible colors are important aspects of photography, HDRI specifically addresses the range of light a camera can capture compared to the human eye. Likewise, noise reduction pertains to the clarity and quality of the image rather than the dynamic range, which is the fundamental focus of HDRI technology.
