George Eastman made the first mass-market, point-and-shoot camera, called the Kodak
Louis Daguerre invented the daguerreotype, a positive black-and-white image on a mirror-polished, silver-plated copper sheet.
Talbot made positive images by contact printing his negatives to other light sensitive sheets.
William Henry Fox Talbot created negatives by soaking sheets of paper in silver chloride and placing them inside camera obscuras
Joseph Niepce created
the oldest surviving
photograph

3. Lens
A disc of transparent glass or plastic with one or more curved surfaces, also called an element

4. Shutter
A mechanism that opens and closes the lens or camera body, allowing light to hit the film or imaging sensor

5. Daguerreotype
A one-of-a-kind positive black-and-white image on a mirror-polished, silver-plated copper sheet.

6. Autochrome
An early color transparency process on glass plates using vegetable starch grains dyed red, green, and blue to make up the image

7. Camera Obscura
Latin for ‘dark room,’ the first camera that was used for centuries as a drawing aid for artists.

8. Normal Lens
A lens that most closely matches the view of the human eye in terms of area, perspective, and proportion

9. Wide-Angle Lens
A lens that includes more of the scene and makes objects look further away than a normal lens.

10. Telephoto Lens
A lens that includes less of a scene and makes objects look extremely close-up.

11. Zoom Lens
A lens with variable focal lengths that changes from wider views to closer views, making the subject appear closer or further away.

12. Negative
A transparent photographic image where the tones or values have been reversed

13. Film Speed
This tells you how sensitive a particular film is to light

14. ISO
Stands for International Standards Organization; a standardized way to measure a film’s light sensitivity; represented as a number ( on digital format cameras)

15. Describe the differences between these two images.
The darker and lighter areas in the first image are reversed in second image.
What is the first image called?
A NEGATIVE

16. What makes a ‘CAMERA OBSCURA’ different from an actual functioning ‘CAMERA’ as we know it today?
What happened when you moved your tracing paper frame closer to the pinhole in your camera obscura? Why?
What happened when you moved your tracing paper frame further away from the pinhole in your camera obscura? Why?
Camera Obscuras alone had no way of permanently recording an image.
You could see more of the scene you were looking at.
The shorter distance between the pinhole and where light was
projected mimics the function of a wide-angle lens.
You could see less of the scene you were looking at, and appeared much closer to you.
The greater distance between the pinhole and where light was projected mimics
the function of a telephoto lens.
