  1. Photography: Historical Perspective

  2. Frisius Gemma's illustration of a camera obscura, 1544. Science and Society Museum/ Universal Images Group • Camera Obscura • Aristotle wrote about light that allows an upside down view of the world through a pin hole in one wall of a dark chamber, 1000 years before the camera

  3. Device is a room or box with a hole in one side. Light from an external scene passes through the hole and strikes a surface inside, where it is reproduced, upside-down; color and perspective are preserved. • Can be projected onto paper, and then traced to produce an accurate representation • Painters used it to trace sketches of scenes on paper to be filled in later with paint Camera Obscura

  4. Joseph Niepce 1826 - Heliography First permanent photograph that can still be viewed The One and Only Heliograph: View from the Window at Le Gras –An 8-Hour Exposure • Niepce combined the camera obscura with photosensitive paper and named the process Heliography

  5. Louis Daguerre 1839: Daguerreotype A Daguerreotype of Louis Daguerre 1839 Daguerreotype: First Image of a Person • Daguerre built on work of Niepce – First practical photographic process using the Camera Obscura • Images on silver-plated copper, coated with silver iodide and "developed" with warmed mercury

  6. Daguerreotype set up

  7. Daguerreotype: Are We Done Yet? Subjects Looked miserable because it wasn’t fun to be photographed sitting still in the same pose for a long period of time

  8. Henry Fox Talbot • 1839: Calotype • Introduced Negative/Positive Images images using paper soaked in silver chloride and fixed with salt solution. • Positive images by contact printing onto another sheet of paper • Patented the process in 1841 under the name Calotype. • Not as clear as Daguerreotypes but was first use of "positive" and "negative”. Calotype by Henry Fox Talbot

  9. Frederick Archer 1851: Wet Collodion Archer improved photographic resolution with Wet Collodion photography Less Expensive than daguerreotypes Negative/positive process permitted unlimited reproductions Process was published but not patented so he didn’t profit Mathew Brady used the Wet-Collodion Process

  10. Wet-Collodion, Frederick Archer, 1851 • Before and After Battle Scenes Civil War Photographs Used the Wet Collodian Process Shutter Speeds Were Still Too Long to Capture Action
