1. 0:00what is shutter speed well it may seem
2. 0:03like the answer is obvious there's more
3. 0:05to shutter speed than meets the eye
4. 0:06let's take a closer look shutter speed
5. 0:09is one of the three pillars of
6. 0:10Photography the other two being ISO and
7. 0:13aperture also known as exposure time
8. 0:16shutter speed is defined as the length
9. 0:18of time the image sensor in a camera is
10. 0:20exposed to incoming light before we go
11. 0:23more in depth however let's take a look
12. 0:25at the different parts of the camera
13. 0:27that contribute to taking a photo in a
14. 0:30standard DSLR when you press the shutter
15. 0:32button a mirror flips up allowing light
16. 0:34to pass into the camera instead of the
17. 0:36viewfinder once the mirror is flipped
18. 0:38upwards a small door will move from top
19. 0:41to bottom exposing the sensor beneath
20. 0:43after that another door will fall down
21. 0:46covering up the entire sensor after the
22. 0:48second door closes your mirror will fall
23. 0:50back into place the doors will then
24. 0:52reset to their original positions
25. 0:54underneath the longer the shutter is
26. 0:56kept open the more light will enter the
27. 0:58camera in auto mode cameras will meter
28. 1:01the scene and determine an adequate
29. 1:03shutter speed to keep the picture from
30. 1:04becoming either over or underexposed you
31. 1:07can manually change the shutter speed by
32. 1:10either putting the camera in shutter
33. 1:12priority mode which will let you change
34. 1:14shutter speed letting the camera
35. 1:16calculate ISO and aperture or full
36. 1:18manual mode which gives you full control
37. 1:21over all your camera settings shutter
38. 1:23speeds are measured in fractions of a
39. 1:25second when under 1 second for example 1
40. 1:28over4 displayed on the camera means the
41. 1:30shutter speed is 1/4 a second whereas 1
42. 1:33over 250 means the shutter speed is 1
43. 1:36250th of a second most cameras can
44. 1:39handle shutter speeds as fast as 1/
45. 1:4114,000 of a second or sometimes even as
46. 1:44high as 1 18,000 of a second and shutter
47. 1:47speeds as long as 30 seconds longer
48. 1:50shutter speeds can be achieved using a
49. 1:51function known as bulb mode where the
50. 1:54shutter speed is determined by the
51. 1:55length of time the shutter button is
52. 1:57activated either manually or through a
53. 1:59remote trigger it's good to know what
54. 2:01effects different shutter speeds have as
55. 2:03it can affect the type of picture
56. 2:05produced short shutter speeds often
57. 2:08quicker than 1 1,000th of a second are
58. 2:10fast enough to capture the fast movement
59. 2:12of Wildlife and sports and freeze water
60. 2:15droplets and small particles for
61. 2:18everyday photography shutter speeds
62. 2:20around 1/1 100th of a second are fast
63. 2:23enough to keep subjects from blurring if
64. 2:25you're shooting handheld longer shutter
65. 2:27speeds may also cause your shaky hand to
66. 2:30blur the photo newer lenses from most
67. 2:32manufacturers have attempted to solve
68. 2:34this problem by introducing vibration
69. 2:37reduction technology and the lenses to
70. 2:39correct for minor shakes night
71. 2:41photography will often utilize longer
72. 2:43shutter speeds to capture as much light
73. 2:46as possible shutter speeds as long as 20
74. 2:48or 30 seconds may even be used to take
75. 2:51pictures of the Milky Way knowing the
76. 2:53principles of shutter speed will allow
77. 2:54you to make better decisions about how
78. 2:56you want your picture to look whether
79. 2:58you're freezing the action creating a
80. 3:00Time Warp effect letting in little light
81. 3:03or as much as you can though it's a very
82. 3:05basic concept of Photography it is no
83. 3:08less important than making a fantastic
