Photography
Drawing with light: capturing images through chemical or electronic means.
Photography is the art, application, and practice of creating images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing, business, art, film and video production, recreation, hobby, and mass communication. The word "photography" was created from Greek roots meaning "drawing with light," and its invention resulted from combining technical discoveries relating to seeing and capturing an image.

Lore & Background
The discovery of the camera obscura dates back to ancient China, with Greek mathematicians Aristotle and Euclid independently describing it in the 5th and 4th centuries BCE. The Arab physicist Ibn al-Haytham (Alhazen) invented the first true pinhole camera and gave the first correct geometrical and quantitative analysis of the camera obscura. Renaissance painters used the camera obscura to project images onto paper. The birth of photography concerned inventing means to capture and keep that image, with early steps including Albertus Magnus's discovery of silver nitrate and Johann Heinrich Schulze's use of a light-sensitive slurry to capture images of cut-out letters.

Niépce partnered with Louis Daguerre, who after Niépce's death developed the daguerreotype process using silver halides, iodine vapor, and mercury vapor, reducing exposure time to minutes.

Frequently Asked Questions
What is Photography?
Photography is the practice of producing permanent images by capturing light, either through an electronic image sensor or a chemically light-sensitive material like film. It sits at the intersection of art, science, and technology.
How does Photography actually work?
At its core, the process involves directing light onto a recording medium—either a digital sensor that converts photons into electrical signals or a film coated with light-reactive chemicals. The result is a lasting two-dimensional representation of a scene.
Where does the word 'Photography' come from?
The term was coined from Greek roots that translate to 'drawing with light,' reflecting the fundamental act of using illumination to render an image. Its invention drew on multiple technical breakthroughs related to how we perceive and record visual information.
What fields does Photography impact?
It is applied across science, manufacturing, business, fine art, film and video production, recreation, and mass communication. Essentially, any industry that needs to document, analyze, or visually communicate benefits from the technique.
What is Photography's most notable contribution?
It is primarily recognized for enabling the creation of permanent, reproducible images simply by recording light. This capability transformed how humanity documents, studies, and shares visual information across virtually every discipline.
