German subtitles for clip: File:Basics of photography – how you learn to shoot better photos.webm

1
00:00:01,000 --> 00:00:03,500
Es ist einfach, bessere Bilder zu machen

2
00:00:04,900 --> 00:00:06,900
Das sind Maria und Paul

3
00:00:07,000 --> 00:00:09,000
Sie freuen sich auf ihren Urlaub

4
00:00:09,300 --> 00:00:12,000
Aber welche Kamera sollen sie mitnehmen?

5
00:00:12,600 --> 00:00:15,900
Maria weiß, daß viele moderne Kameras so gut sind,

6
00:00:16,000 --> 00:00:19,500
daß sie in der Regel gute Fotos mit Automatik machen.

7
00:00:20,000 --> 00:00:23,400
Aber manche Fotos werden nicht gut.

8
00:00:23,600 --> 00:00:25,200
Was kann Maria besser machen?

9
00:00:26,100 --> 00:00:29,100
"Fotografie" bedeutet wörtlich "Malen mit Licht".

10
00:00:29,500 --> 00:00:33,000
Warum? Alles um uns herum reflektiert Licht

11
00:00:33,200 --> 00:00:34,700
in der Umgebung.

12
00:00:34,900 --> 00:00:37,000
A camera lens capture those rays.

13
00:00:37,200 --> 00:00:40,000
That's what form a picture in the camera.

14
00:00:41,000 --> 00:00:44,400
The light, and therefore the photo quality,

15
00:00:44,400 --> 00:00:47,000
is controlled by several determining factors.

16
00:00:47,300 --> 00:00:53,200
The most important one are aperture, exposure time and light sensivity.

17
00:00:54,700 --> 00:00:58,400
Imagine the aperture as a pair of curtains.

18
00:00:58,600 --> 00:01:01,600
It control the amount of light entering the lens

19
00:01:01,600 --> 00:01:02,400
When it's dark,

20
00:01:02,500 --> 00:01:04,800
Mary want to capture as much light as possible.

21
00:01:05,100 --> 00:01:08,000
To do that, she need to open the aperture wider.

22
00:01:09,500 --> 00:01:10,900
If it's very bright,

23
00:01:11,300 --> 00:01:14,600
Mary draw the aperture curtains closer together.

24
00:01:14,800 --> 00:01:18,000
Otherwise her pictures will be overexposed.

25
00:01:19,200 --> 00:01:22,000
The "f" number, or "focal ratio",

26
00:01:22,100 --> 00:01:25,400
specify up to how far the curtains can be opened.

27
00:01:25,700 --> 00:01:28,200
At f2, only halfway. 

28
00:01:29,100 --> 00:01:32,800
At f4, only a quarter of the way. 

29
00:01:33,400 --> 00:01:35,500
So, the lower the number, 

30
00:01:35,500 --> 00:01:38,100
the more light can pass through a particular lens. 

31
00:01:38,500 --> 00:01:41,300
But those aperture curtains don't always stay open. 

32
00:01:41,600 --> 00:01:43,400
They only open for a spit second. 

33
00:01:43,700 --> 00:01:49,000
That lenght of time is called the "exposure time" or "shutter speed". 

34
00:01:49,300 --> 00:01:50,900
The longer the exposure time, 

35
00:01:51,100 --> 00:01:52,700
the more light enter the photo. 

36
00:01:52,900 --> 00:01:57,400
That's fantastic. Mary want to take a photo at twilight for example. 

37
00:01:58,300 --> 00:02:00,700
If a car drive to the photo, 

38
00:02:01,000 --> 00:02:03,200
it will reflect the light from different positions. 

39
00:02:03,500 --> 00:02:05,400
So it just apear blurry in the picture. 

40
00:02:06,600 --> 00:02:07,900
The same thing will happen 

41
00:02:08,200 --> 00:02:11,000
if Mary move slightly while taking the photo. 

41
00:02:11,200 --> 00:02:14,100
That's why, when using long exposure time, 

42
00:02:14,400 --> 00:02:18,200
the camera should always be resting on a steady surface. 

43
00:02:18,100 --> 00:02:19,900
But when it's bright out,

44
00:02:20,100 --> 00:02:22,400
Mary only need to briefly expose her photos, 

45
00:02:22,700 --> 00:02:25,500
so the car come out nice and sharp. 

46
00:02:26,000 --> 00:02:28,000
No tripod needed. 

47
00:02:28,700 --> 00:02:30,600
Mary still isn't quite satisfied. 

48
00:02:31,000 --> 00:02:34,200
Despite using a wide open aperture and a long exposure time,

49
00:02:34,500 --> 00:02:36,900
the result is still too dark. 

50
00:02:37,200 --> 00:02:38,600
That's where "light sensivity", 

51
00:02:39,000 --> 00:02:40,900
or "ISO", come into play. 

52
00:02:41,200 --> 00:02:44,400
It's more or less the photo "skin type", 

53
00:02:44,700 --> 00:02:46,400
and determine how sensitively the 

54
00:02:46,700 --> 00:02:47,400
camera react to the light. 

55
00:02:48,700 --> 00:02:50,900
High sensivity can quickly lead to a sunburn. 

56
00:02:51,300 --> 00:02:54,400
Then, the photo as something call "noise". 

57
00:02:57,000 --> 00:02:58,700
Mary is overwhelmed. 

58
00:02:59,000 --> 00:03:01,000
Fortunately, she doesn't have to do everything manually

60
00:03:01,300 --> 00:03:03,200
to take pretty pictures. 

61
00:03:03,500 --> 00:03:06,700
In semi-automatic mode, Mary specify just one value. 

62
00:03:07,800 --> 00:03:09,500
The camera figure out the rest. 

63
00:03:10,700 --> 00:03:13,800
Even so, the perfect settings for all situations 

64
00:03:14,200 --> 00:03:16,000
just doesn't exist. 

65
00:03:16,300 --> 00:03:18,900
A good photographer react to prevail light conditions, 

66
00:03:19,800 --> 00:03:23,400
use average values, and accept a compromise now and then. 

67
00:03:25,000 --> 00:03:28,400
It's almost like a healthy relationship.
