What is the history of photography?

When was photography invented?

The history of photography began long before the first successful image. Ancient scholars, including Mozi in China and Aristotle in Greece, understood the principles of the camera obscura, a darkened room where light passing through a small hole projects an inverted image of the outside world onto a wall. However, these projections could not be captured permanently until the 19th century.

In 1826, French inventor Joseph Nicéphore Niépce produced the first permanent photograph, View from the Window at Le Gras. He coated a pewter plate with bitumen of Judea, a light-sensitive asphalt, and exposed it for eight hours. While the image was blurry and required a long exposure, it proved that light could physically alter a surface to record a scene.

Following Niépce’s death, his partner Louis Daguerre refined the process. In 1839, he introduced the daguerreotype, which used silver-plated copper sheets treated with iodine vapor. This method reduced exposure times to minutes and produced incredibly sharp, detailed images. The French government purchased the patent and released it to the world, sparking a global obsession with portraiture and documentation.

How did film photography evolve?

As the daguerreotype gained popularity, inventors sought ways to make photography more accessible and reproducible. In 1841, William Henry Fox Talbot patented the calotype process, which used paper negatives to create multiple positive prints. This shifted the medium from a single unique object to a process of mass production, laying the foundation for modern printing.

By the 1870s, the "wet plate" collodion process dominated, requiring photographers to coat, expose, and develop glass plates before they dried. This was cumbersome, as it required portable darkrooms. The invention of the "dry plate" in the 1870s changed everything, allowing plates to be prepared in advance and stored. This innovation paved the way for George Eastman to introduce flexible roll film in 1888.

1. The Kodak camera was released in 1888, pre-loaded with enough film for 100 photos.
2. Users would mail the entire camera back to the factory for development.
3. The factory returned the developed prints and the reloaded camera to the customer.
4. This "You press the button, we do the rest" slogan democratized photography for the general public.

What are the basics of manual photography?

Understanding the history of photography requires grasping the "exposure triangle," the three settings that control the light entering a camera. These principles remain the foundation for both film and digital photography today. Mastering these allows a photographer to dictate how a scene is rendered, rather than relying on automatic settings.

• Aperture: The size of the lens opening, measured in f-stops. A low number (e.g., f/1.8) creates a shallow depth of field, blurring the background.
• Shutter Speed: The duration the sensor or film is exposed to light. Fast speeds freeze motion, while slow speeds create motion blur.
• ISO: The sensitivity of the medium to light. Lower ISOs produce cleaner images, while higher ISOs allow for shooting in darker conditions but introduce "noise" or grain.

Common mistakes when learning manual photography:

1. Ignoring the light meter, which tells you if your image will be too bright or dark.
2. Using a shutter speed that is too slow while holding the camera, leading to blurry, shaky images.
3. Over-relying on high ISO settings, which degrades image quality unnecessarily in well-lit environments.

Why do photos fade over time?

The longevity of a photograph depends on its chemical composition and storage environment. Early daguerreotypes were delicate and prone to oxidation, while paper prints from the 19th and 20th centuries often suffered from improper chemical washing. Residual chemicals, such as fixer, can slowly eat away at the silver particles that form the image, causing yellowing or fading.

Environmental factors are the primary enemies of physical photographs. UV light, high humidity, and fluctuating temperatures accelerate the breakdown of dyes and paper fibers. To preserve historical photographs, archivists use acid-free sleeves, archival boxes, and climate-controlled storage. By minimizing exposure to light and oxygen, collectors can ensure that images survive for generations without significant degradation.

If you are storing old family photos, follow these practical steps:

• Avoid using magnetic "sticky" albums, as the adhesives are acidic and will damage photos.
• Store prints in a cool, dry place, such as an interior closet, rather than an attic or basement.
• Use white cotton gloves when handling original negatives or prints to prevent oils from skin transferring to the surface.

How to start with film photography today?

Starting with film photography offers a tactile experience that teaches patience and precision. Unlike digital cameras, film requires you to be deliberate with every shot because each frame has a financial cost. This constraint often forces beginners to slow down, compose more carefully, and truly understand the relationship between light and the subject.

To begin, purchase a reliable, fully mechanical 35mm camera, such as a Canon AE-1 or a Pentax K1000. These cameras are robust and feature built-in light meters that simplify the learning process. Pair the camera with a standard 50mm lens, which mimics the field of view of the human eye. Always keep a notebook to record your settings for each roll, as this helps you identify which techniques work best in different lighting conditions.

Common mistakes when starting with film:

• Loading the film incorrectly, which can lead to the film not advancing and resulting in blank rolls.
• Opening the camera back before the film is fully rewound, which exposes and ruins the entire roll.
• Using expired film without adjusting your exposure settings to compensate for the loss of sensitivity over time.
