00:00:00,320 --> 00:00:05,359
have you ever noticed the little F numbers around the lens on a camera have

2
00:00:03,719 --> 00:00:08,679
you ever wondered what they might mean it's called f-stop and it's a

3
00:00:06,879 --> 00:00:12,519
measurement of the possible range of sizes for a camera's aperture which is

4
00:00:10,840 --> 00:00:16,760
the opening in a camera through which light enters the wider the aperture is

5
00:00:15,200 --> 00:00:20,640
the more light can get through onto the camera sensor which is necessary for

6
00:00:18,880 --> 00:00:25,240
properly exposing lighter or darker scenes the f-stop number or focal ratio

7
00:00:23,599 --> 00:00:29,320
indicates how much light is getting through and each marked f- stop is

8
00:00:27,039 --> 00:00:33,399
either double or half as much light but it's not very intuitive because the

9
00:00:30,759 --> 00:00:37,320
smaller numbers actually indicate wider aperture sizes now on some cameras like

10
00:00:35,640 --> 00:00:41,280
cell phone cameras the f-stop or aperture size is automatically decided

11
00:00:39,480 --> 00:00:45,079
for you but if you can adjust it manually it's worth doing if you want to

12
00:00:43,239 --> 00:00:48,239
take a better picture by adjusting the aperture not only can you change the

13
00:00:46,600 --> 00:00:52,000
brightness of an image but also the depth of field depth of field is

14
00:00:50,320 --> 00:00:55,960
basically the full extent of everything that's in focus in a picture a deeper

15
00:00:54,440 --> 00:00:59,640
depth of field means that more of the image is in focus and a shallower depth

16
00:00:57,920 --> 00:01:03,239
of field means that less of the image is in focus Focus this means that a scene

17
00:01:01,760 --> 00:01:06,840
can be photographed with the foreground and background blurred out which allows

18
00:01:05,080 --> 00:01:10,799
for the main subject of the photograph to stand out more it looks really good

19
00:01:09,040 --> 00:01:14,759
but when you widen the aperture the picture also gets brighter so you have

20
00:01:12,680 --> 00:01:18,880
to compensate for that overexposure by adjusting other camera settings like ISO

21
00:01:16,880 --> 00:01:22,680
or shutter speed some cameras like a DSLR can automatically adjust these

22
00:01:20,759 --> 00:01:26,960
settings for you when put in aperture priority mode since a blurry background

23
00:01:25,079 --> 00:01:30,560
can look really good if done correctly I used to always take pictures with the

24
00:01:28,400 --> 00:01:34,920
aperture set as wide as possible so a low F stop to give myself the shallowest

25
00:01:32,759 --> 00:01:39,000
possible depth of field however lately I've learned that this very shallow

26
00:01:36,520 --> 00:01:43,119
depth of field is not always desirable this was shot with a macro lens and the

27
00:01:40,720 --> 00:01:46,640
focus is millimeter thin making it difficult to see the whole subject it's

28
00:01:44,759 --> 00:01:50,600
up to you how much or how little depth of field you want for your pictures and

29
00:01:48,640 --> 00:01:55,159
videos and changing the aperture is a great way to control that but if you

30
00:01:52,479 --> 00:01:59,000
want more control over your facial hair I'd suggest Dollar Shave Club you might

31
00:01:57,320 --> 00:02:03,560
remember that last time I did a spot for these guys I shaved off my whole beard

32
00:02:01,520 --> 00:02:07,200
many of you cried out in protest and so I think I'll keep it this time around

33
00:02:05,479 --> 00:02:10,959
but I should probably continue to shave the neck beard and if you don't want to

34
00:02:09,160 --> 00:02:15,319
be a neck beard you should join Dollar Shave Club Dollar Shave Club shaves you

35
00:02:13,200 --> 00:02:19,080
time and shaves you money by delivering highquality razors to your door once a

36
00:02:17,160 --> 00:02:22,400
month for a few bucks a month it's like getting a little present in the mail

37

38
00:02:24,519 --> 00:02:31,200

39
00:02:28,319 --> 00:02:34,959
