Nature Science+Photography Volume 1: Image Creation, Depth, Size

Volume 1 of the series Nature Science+Photography addresses fundamental questions regarding visual perception and photographic image formation:

How does our sense of sight function in the interplay between eye and brain?
How are photographic images created?
Why do we perceive our environment in three dimensions?
What factors must we take into account to convey spatial depth in our photographs?
What governs our perception of object sizes—and their subsequent depiction?
The volume concludes with a physiologically grounded set of recommendations on what we should do in photography to capture visually compelling images.

This volume serves as an entry point to the series, laying a physiological and scientific foundation for advanced photographic mastery.

Chapter 1 delves into the brain's remarkable processing of visual information, tracing the journey from photons striking the retina to the construction of coherent perceived images. It reveals that the “reality” we see is not a direct replica of the world but an elaborate mental model assembled by neural circuits, influenced by context, expectations, and evolution adaptations.

Chapter 2 draws parallels between image formation in traditional analog photography (film emulsions and chemical development) and modern digital systems (sensor arrays and algorithmic processing), highlighting shared principles like light sensitivity and dynamic range.

Chapters 3 and 4 shift focus to the perception and photographic representation of spatial depth. They explain how our binocular vision and monocular cues enable us to infer three-dimensionality from flat, twodimensional projections, and detail practical photographic strategies— such as lens focal length, perspective distortion, and layering—to amplifythe illusion of depth.

Chapters 5 and 6 investigate how we perceive and depict object sizes, addressing scale illusions, relative proportions, and the role of context in size constancy.
