The Invention of Photography

At some point, we all have this question who and when photography was invented? Photography is a method of recording of images through light or radiation. The word photography came from two Greek words Phos (Light), Graphis (Drawing/writing) which means writing with light. Drawing with light is different than drawing with a pen, it requires a light-sensitive material, optics and a dark enclosed room. The history of photography begins with two important principles- Camera Obscura image projection and observation of the effect of light exposure on certain substances.

At the beginning of the 19th century, scientists and artists started exploring new ways to capture images and create permanent records of things. In this article, we will explore a detailed overview of the invention of photography, where photography first started, what led to the invention of photography and the key milestones that led to its development.

Pre-photography Era

While the first permanent photograph wouldn’t appear until the 19th century, the seeds of this revolutionary technology were sown thousands of years earlier.

1000 Years ago-

Arab scientist Alhazen

 

Long before we captured fleeting moments on film, a brilliant Arab scholar named Ibn al-Haytham, known in the West as Alhazen, delved into the mysteries of light and optics around 1021. His magnum opus, the 7-volume “Book of Optics”, wasn’t just a book; it was a revolutionary exploration that profoundly influenced the understanding of light for centuries to come.

Beyond Descriptions: A Life of Experimentation and Innovation

Unlike many scholars of his time who relied solely on theory, Alhazen was a true scientist at heart. He conducted meticulous experiments, meticulously documenting his observations and using logical reasoning to draw groundbreaking conclusions. This hands-on approach led him to uncover fundamental truths about light, including:

• Light travels in rays and straight lines: This seemingly simple principle overturned prevailing beliefs about light emanating from the eye, paving the way for future advancements in lenses and telescopes.
• Image magnification with lenses: Alhazen’s experiments with lenses laid the foundation for the invention of eyeglasses, forever changing the way we see the world.
• Pinhole size and image sharpness: He discovered that adjusting the size of the pinhole in a camera obscura produced sharper projected images, demonstrating his keen understanding of light intensity and focus.

The Camera Obscura: A Vision of the Future

While Alhazen may not have personally built the first camera obscura, his detailed descriptions in the “Book of Optics” were instrumental in its development. This darkened chamber with a small opening projected an inverted image of the outside world onto a screen, offering a glimpse into the potential of capturing and manipulating light.

Early Life

• Alhazen’s early life remains shrouded in some mystery, but records suggest he faced persecution for his progressive views on science and religion.
• Despite the challenges, he remained undeterred, dedicating his life to research and writing. His dedication earned him the title of “The Second Ptolemy” for his groundbreaking contributions to optics.
• The “Book of Optics” wasn’t just a technical treatise; it explored philosophical and psychological aspects of vision, demonstrating Alhazen’s holistic approach to understanding the world.

13th Centuri- The invention of Eyeglasses and Roger Bacon

Roger Bacon, the 13th-century English scholar, wasn’t just a passive conveyor of knowledge. While his book “Opus Majus” (1267) did indeed disseminate Alhazen’s groundbreaking discoveries about optics, Bacon went beyond mere translation. He actively contributed to the evolution of both eyeglasses and the camera obscura:

• Beyond Magnification: While magnifying glasses had existed before, Bacon’s detailed descriptions and experiments fueled their widespread adoption, leading to the creation of the first practical eyeglasses. These early spectacles weren’t just for correcting vision but also for scientific observation and reading, impacting various fields.
• Refining the Camera Obscura: Bacon wasn’t just content with understanding the camera obscura’s principle. He actively sought to improve its functionality, potentially contributing to the development of diaphragms to control light and refine image quality.

While history often focuses on the inventor, it’s crucial to acknowledge the role of investors who enabled these innovations to flourish. In Bacon’s case, his patrons included:

• Guy de Beauchamp, Earl of Warwick: A powerful nobleman who supported Bacon’s research and provided financial backing for his experiments.
• Pope Clement IV: Recognizing the potential of Bacon’s work, the Pope offered him access to resources and encouraged his scientific pursuits.

These patrons, along with others, played a crucial role in nurturing Bacon’s genius and ensuring his ideas found fertile ground.

• Willebrord Snellius: This Dutch mathematician and astronomer refined the understanding of lenses and contributed to improved image quality in camera obscuras.
• Johann Zahn: This German mathematician and astronomer invented a portable camera obscura with a mirror that projected the image right-side up, making it more user-friendly for artists.

17th Centuri- Light-sensitive material:

Humans have long observed the transformative power of light. From the tanning of skin under the sun to the fading of fabrics, everyday experiences hinted at light’s ability to alter materials. Yet, harnessing this power for image capture remained a distant dream.

Unveiling the Silver Lining: Angelo Sala’s Experiment (1614)

In 1614, Italian physician and chemist Angelo Sala made a crucial discovery. He observed that silver nitrate powder darkened upon prolonged exposure to sunlight. While he couldn’t capture permanent images, Sala had stumbled upon a key property: light’s ability to chemically alter a specific material.

Beyond Silver Nitrate: A Kaleidoscope of Light-Sensitive Chemicals

Sala’s discovery sparked further exploration. Scientists like Johann Heinrich Schulze (1727) and Carl Wilhelm Scheele (1777) experimented with various light-sensitive chemicals, including silver chloride and silver bromide. These investigations revealed a broader range of materials susceptible to light’s transformative power.

Paper’s Role: Capturing the Ephemeral:

Observing that paper exposed to silver nitrate alongside objects also darkened, researchers like Johann Heinrich Schulze realized paper could act as a recording medium. This marked a significant step towards capturing fleeting images.

From Curiosity to Collaboration: Building upon Each Other’s Work

The journey wasn’t linear. Many scientists contributed, building upon each other’s discoveries. For example, Thomas Wedgwood (1802) used sunlight to create silhouettes on paper coated with silver chloride, while Humphry Davy (1802) observed that light intensity influenced the degree of darkening.

The Puzzle Nears Completion: Understanding Light’s Action on Chemicals

Despite these advancements, researchers faced a crucial hurdle: the image darkened upon further exposure to light, preventing permanence. It wasn’t until Sir John Herschel (1839) discovered that sodium thiosulfate could fix the image, making it stable to further light exposure, that a crucial piece of the puzzle fell into place.

The Legacy: Setting the Stage for Photography

By the early 19th century, the understanding of light-sensitive materials was reaching a critical point. With permanent image fixation achieved, inventors like Louis Daguerre and Joseph Nicéphore Niépce were poised to usher in the era of photography.
