The camera has evolved greatly over centuries from early prototypes like the camera obscura to modern digital cameras. The camera obscura provided the first means to project images but could not capture them permanently. The daguerreotype introduced in 1830 was the first true camera, using a copper plate to capture light, though exposures took 15 minutes. Advances like emulsion plates, dry plates, and flexible film made cameras more portable and practical. In the modern era, digital cameras replaced film and made photography accessible to all with instant previews and easy editing of photos. Cameras continue to evolve with new technologies.

3. According to Wikipedia:
A camera is a device that records/stores images. These images may be still photographs or
moving images such as videos or movies. The term camera comes from the camera obscura
(Latin for "dark chamber"), an early mechanism for projecting images. The modern camera
evolved from the camera obscura.
Cameras may work with the light of the visible spectrum or with other portions of the
electromagnetic spectrum. A camera generally consists of an enclosed hollow with an opening
(aperture) at one end for light to enter, and a recording or viewing surface for capturing the light
at the other end. A majority of cameras have a lens positioned in front of the camera's opening
to gather the incoming light and focus all or part of the image on the recording surface. Most
20th century cameras used photographic film as a recording surface, while modern ones use an
electronic camera sensor. The diameter of the aperture is often controlled by a diaphragm
mechanism, but some cameras have a fixed-size aperture.
The still camera takes one photo each time the user presses the shutter button. A typical movie
camera continuously takes 24 film frames per second as long as the user holds down the shutter
button, or until the shutter button is pressed a second time.
From its inception, the camera has been instrumental in the recording of still images from then-
present surroundings, and further modifications led to the development of motion picture
sequences in the late 19th century. Cameras and the exhibition of camera-captured images are
widely used in both professional and consumer settings in the 21st century for both mass and
interpersonal communication purposes.

In short,
A camera is anything that
can record/store images.

5. and
They come…

6. …in all
shapes
and
sizes.

7. If we
consider about
The
history

8. The
First Camera
Is…

9. CAMERA OBSCURA
11th century

10. CAMERA OBSCURA
11th century
How it worked:

11. CAMERA OBSCURA
11th century
How it worked: The light from an
object (A) passes
through a pinhole,
which shows up in the
camera obscura’s
other side as an
inverted image (B).

12. Actually…

13. It’s more of a
Projector
than a
camera.

14. Since it can’t
really store the
image.

15. It just
Projects
it.

16. Here is a picture of it

18. The very first
TRUE
CAMERA

19. is the
Daguerreotype
TIME: (1830)

20. Which uses
a special
copper plate
To
capture the light
from
the image.

21. But
the only problem is:

22. It takes up to
15 minutes
to fully capture the image.
of EXPOSURE

23. It makes you feel sorry for these
guys:

24. It makes you feel sorry for these
guys:
Notice the frowns on their faces.

25. Then…

26. EMULSION PLATES
were INVENTED.
TIME: (1850s+)

27. which only take
2-3 seconds
of exposure time.

28. Then…

29. DRY PLATES
were born. 1850

30. which can be stored for future use.

31. These cameras were

32. And looked like
the monster
tripods from
the
‘War of the
Worlds’
movie.

33. But…

34. The world needed

35. portable cameras
1880

36. So it was invented by…

37. John Strognofe

38. It is…

40. Then..

41. flexible roll films were
created by

42. George Eastman

43. It made
portable cameras
possible.

44. 35mm Film
Became THE
STANDARD
for cameras and is
still being used NOW.
The

45. Ur-leica
The
FIRST
35mm film
camera
1914

46. After 30 years later…

47. POLAROID
CAMERASwere born.
1948
which created…

48. INSTANT
IMAGES

50. After that…

51. SLR CAMERAS 1948
were created.

52. Which were the
first cameras
that can take images of
“what you see
is
what you get”

53. Also known as
WYSIWYG
(What You See Is What You Get)
Cameras

54. Everything was going well for
our photographers,

55. UNTIL…

56. DIGITAL CAMERAS
TIME: (1991)
Which have greatly
CHANGEDthe way cameras work.

57. Now, there’s no
NEEDto get perfect photos.

58. You can easily DELETE ugly shots
and just take another one.

59. THANKS to technology,

60. Cameras can now be found

61. Cameras can now be found
ANYWHERE

63. COMPUTERS

64. COMPUTERS

65. Cameras have EVOLVED.

66. Cameras are
