Are you sure you know what a photo is?

as a child, I would sit on the balcony of our Dhaka apartment overlooking the pond and flip through our two family albums. After the Bangladesh Liberation War in 1971, film was scarce and our cameras broke. With nowhere to repair or buy film, we haven’t had more family photos in nearly a decade. There were no pictures of me until I was 8 years old.

Those tiny, jewel-like black-and-white prints of my parents and brother are fragments of my history that, as curator Gren Helfand puts it, “capture a fraction of a second of activity and serve as a narrative for generations to come. Provided the motivation.” These images were absorbed into my soul, stored as evidence of my pre-birth family story, and now on my child’s iPhone.

On the balcony by that pond, I knew exactly what the photo was. Later, I will learn the technical language of these images: 2D photo-registration on cellulose negative, then printed on silver halide paper. However, 25 years later, sitting in my studio surrounded by thermal cameras, lidars, 3D printers and AI software, I’m not so sure anymore.

Much of today’s photo criticism and theories are still actively debating the past, with little regard for what’s to come. For example, American artist Trevor Paglen’s 2017 exhibition “Invisible Image Research“Investigates “machine vision”—images made by machines for consumption by other machines, such as facial recognition systems. Jerry Saltz, Senior Art Critic New York magazine, announcing that the work is “conceptual zombie formalism“based on “smart pants jargon” rather than seriously engaging with the implications of his work. On the theoretical side, a large part photography theory, a 451-page book often used in teaching, focuses on indexability, the idea that taking a photo leaves a physical trace of the subject being photographed. This is problematic in analog photography, but completely absent in digital photography, unless the information is treated as a trace. Likewise, the book makes no mention of new or emerging technology and how it affects photography.

Evolving technologies affect every step of the photo-making process, and photographers are using them to question the very definition of photography itself. Is it a photo when it only captures light? Is it time for physical printing? When the image is 2D? Is it interactive? Object or Information? Or something else?

go digital

Photography – from Greece Character Photo and graphics, which means “painting with light” – began in the 19th century when capturing light reflected off objects onto chemically coated media, such as paper or polished boards. This evolved with the use of negatives, allowing multiple photos to be made. The production steps of capturing, handling and printing involve starting and stopping chemical reactions on the printing paper and negative.

Through analog photography, chemical reactions capture the physical reality directly in front of the camera. However, with digital photography, image production involves counting the number of photonic light particles hitting each sensor pixel, processing the information using a computer, and, in the case of a color sensor, performing further calculations to determine the color. Captures only digitized bits of information – surfaces that leave no physical traces. Because data is easier to process and manipulate than chemicals, digital photography allows for a greater variety and versatility of image processing possibilities. The film theorist Mary Ann Doane once said that numbers represent “a vision (or nightmare) of a medium without materiality, pure abstraction incarnated as a series of 0s and 1s, pure existence. And non-existence, code. Even light, the most transparent substance, is translated into digital form in a digital camera.”

Evolving Image Capture

Analog photo taken “Actinic light” is a narrow strip of the electromagnetic spectrum visible to the naked eye that causes photochemical reactions. Over time, photographers have expanded this beyond optics to create images using infrared, X-rays, and other parts of the spectrum, such as thermal imaging.

Irish photographer Richard Mosse uses a camera to capture the contours of heat rather than light. Traditionally used for military surveillance, the camera allows him to photograph what we can’t see – it can detect humans at night or through tents up to 18 miles away. In 2015, Moss created a work on the refugee crisis called “heatmap,” capturing what art critic Sean O’Hagan called “the white-hot affliction of the immigration crisis,” showing monochrome images with shimmering landscapes and ghostly figures. Unlike Light , the heat signature was unable to distinguish facial features, thus transforming the human figure into a faceless statistic representing how immigrants were typically treated.

Any form of information can be captured for imaging. Artists used other inputs such as acoustic signals, matter particles such as electrons, and other forms of waves. American artist Robert Dash uses electron microscopes, using matter waves rather than light waves, to create very high-magnification images of natural objects, such as pollen or seeds found on the property he lives in. He then montages these photos with life-size photographs of the same objects, creating a surreal microscopic world.the first time i saw these photos, my eyes were scanning the landscape for any signs that could help find where the image might be taken, but without success.

Evolving Image Processing

image processing, traditionally Anything done during the printing process is to create the final image, from darkening the sky in a landscape photo to using Instagram filters or editing in Adobe Photoshop.recent documentaries Black Holes | The Edge as We Know It An advanced version of digital image processing is shown. The documentary explores the process of making the first black hole photo, a process that took 250 people about a decade.

Using a novel mathematical model, the researchers constructed this image by computationally combining years of radio frequency data collected from multiple observatories around the world. This image shows the halo around the supermassive black hole at the center of the galaxy M87.It continues the tradition of photography that transcends human perception, revealing and encoding previously invisible dimensions of reality into visible knowledge, as Edward Muybridge 150 years ago, he used photography to study the groundbreaking work of the movement.

With the development of artificial intelligence, the steps of image processing can go further.For example, Paglen Generate portraits By creating a facial recognition model of his collaborator, then using a second model to generate random images using polygons to trick the first model into thinking it was a portrait. Then, as Paglen explains, “the two programs run back and forth until the image ‘evolves’ and the facial recognition model recognizes it as a representation of that particular person.” portrait.
