However, before succumbing to the belief that these manipulations have drained the essence and practicality from photography, it is crucial to consider the context when evaluating photos.

While skepticism is warranted in today’s landscape, particularly with emotionally charged social media images of influencers or distressing conflicts, photos that hold personal significance—such as those from friends, family, or colleagues—are more likely to be grounded in reality. Moreover, advancements in technology are paving the way for establishing trust in crucial photos, such as those used in insurance claims or disseminated by the news media.

In this article:

Jeremy Garretson, a professional photographer based in New York, navigates the nuances of context across various photography genres, including photojournalism, event coverage, portraiture, and landscapes. For Garretson, the concept of truth in photography exists on a spectrum.

Garretson remarked, “To claim that photography should be universally trusted undermines the essence of photography and art. When viewing a portrait, some degree of truth is expected, even if retouching is involved, such as blemish removal. In photojournalism, trust is paramount, as ethical standards come into play. On the other hand, art is subjective and open to interpretation, devoid of trust.”

Photographs play a significant role in our digital existence, and after engaging with numerous experts, it is evident that their impact will endure despite the challenges surrounding trust. Embracing AI photo processing is essential, as it enhances the creative potential of photography without compromising its integrity. Therefore, acknowledging the subtleties in this era of rapid technological evolution is imperative.

Digital photography 101: From light to JPEG

First and foremost, it is essential to dispel the myth of an unprocessed photo, whether digital or film. Every photograph undergoes processing, as cameras never capture the objective truth of a scene. Each photo reflects the decisions made by engineers to optimize image quality.

To comprehend this concept, let’s delve into the intricacies of digital photo capture.

The initial moment of capture transpires when light photons reach a digital image sensor, a specialized chip tasked with converting light into pixel data. While each pixel can capture red, green, or blue information, a complete photo necessitates all three color components in each pixel. Consequently, cameras employ “demosaicking” algorithms to interpolate missing color data, such as inferring red and blue data in a pixel solely capturing green light.

Hany Farid, a professor at the University of California, Berkeley, specializing in photo authenticity, highlighted that a significant portion of pixel data is generated by devices rather than recorded. This process, known as demosaicking, has evolved over decades to handle intricate details like hair textures or fabric patterns.

Moreover, modern advancements like pixel binning technology enable cameras to group pixel patches into larger virtual pixels, enhancing detail and resolution. Notably, smartphones like the Google Pixel and Samsung Galaxy S23 Ultra employ AI algorithms to refine image quality, demonstrating the convergence of technology and photography.

Smartphone cameras, renowned for their computational photography capabilities, leverage AI to enhance image quality in real-time. Qualcomm’s imaging lead, Judd Heape, emphasized the processor’s ability to differentiate various elements within a scene, such as skin, hair, or sky, to optimize pixel adjustments dynamically.

In essence, AI revolutionizes photo processing by recognizing intricate details and refining image quality, albeit with the potential for reproducing training data biases. This technological progression underscores the transformative impact of AI on modern photography practices.

Human interpretation imbued in photographs

Color representation poses a significant challenge in automated photo processing, particularly concerning nuanced lighting scenarios. Cameras must navigate complex color interpretations, such as compensating for blue hues cast on shaded subjects or resolving color discrepancies in a scene.

Noteworthy examples include the captivating images captured by the James Webb Space Telescope, which translate infrared data into visible colors for human comprehension. Kevin Gill, a developer at NASA’s Jet Propulsion Laboratory, emphasized the interpretive nature of color adjustments in photos, especially when revealing unseen light spectrums like infrared data from Saturn’s storms.

Similarly, smartphone cameras endeavor to convey scenes authentically by employing HDR technology to merge multiple frames into a cohesive image, thereby enhancing tonal range and visual appeal. However, HDR’s widespread adoption has introduced color representation challenges, particularly in diverse skin tones. Isaac Reynolds, leading Google’s Pixel camera development, highlighted the industry’s efforts to address color biases and enhance representation accuracy, especially for darker skin tones.

The evolution of smartphone imaging underscores the delicate balance between realism and aesthetic appeal in photo processing. As smartphones refine their computational photography capabilities, users are presented with vibrant, visually appealing photos that may deviate from strict realism.
