  • Joseph Niépce in the window of his upper-story workroom at his Saint-Loup-de-Varennes country house, Le Gras, he set up a camera obscura, placed within it a polished plate coated with bitumen of Judea (an asphalt derivative of petroleum, an compound dating back to the time of the Egyptians This material has the unusual property of hardening in light not blackening like silver salts but its light sensitivity is small ) and uncapped the lens. After at least a day-long exposure of eight hours, the plate was removed and the latent image of the view from the window was rendered visible by washing it with a mixture of oil of lavender and white petroleum which dissolved away the parts of the bitumen which had not been hardened by light. The result was the permanent direct positive picture  of " a view from nature. "

    1. 1. Intro to Photography
    2. 2. What is ‘photography’ • Photography is derived from the Greek words photos (light) and graphos (drawing). It is the art, science, and practice of creating lasting images by recording light. • Today we use mobile phones and digital cameras to create photographs but this wasn’t always the case...
    3. 3. HOW was the camera invented? • The camera was a technological development that started first with the discovery of a technological device called the camera obscura. This technology first created an image of a scene that dates back to ancient China! • The camera obscura literally means “dark chamber” in Latin. It is a box with a hole in it which allows light to go through and create an image onto the piece of paper. A camera obscura receives images just like the human eye—through a small opening and upside down. Our brain turns the images the right way up. In a camera, a mirror is used.
    4. 4. Leonardo da Vinci mentions natural cameras obscura that are formed by dark caves on the edge of a sunlit valley. Photographer Abelardo Morell’s camera obscura turns darkened rooms into magical landscapes (Printed in National Geographic Magazine) Central Park, New York City A hole in the cave wall will act as a pinhole camera and project an upside down image on a piece of paper. So the birth of photography was primarily concerned with developing a means to fix (make permanent) and retain (keep) the image produced by the camera obscura.
