100:00:00,000 --> 00:00:06,150high-

1
00:00:00,000 --> 00:00:06,150
high-speed think versus neutral density
filters which is the best method for

2
00:00:06,150 --> 00:00:10,130
synchronizing flash and you know it
before you can talk about which is the

3
00:00:10,130 --> 00:00:14,500
best method in the pros and cons of each
what the heck is flash synchronization

4
00:00:14,500 --> 00:00:16,699
let's talk about that

5
00:00:16,699 --> 00:00:21,109
well basically when you fire your your
camera we talked about before when you

6
00:00:21,109 --> 00:00:25,019
press the shutter release your front
door opened and the rear curtain trails

7
00:00:25,019 --> 00:00:28,660
and the amount of time it between those
two things happening is your shutter

8
00:00:28,660 --> 00:00:35,489
speed if your shutter speed is set to a
you know fairly slow speed then it's

9
00:00:35,489 --> 00:00:40,300
very easy for that flashed a power up
and fire within the amount of time it

10
00:00:40,300 --> 00:00:43,510
has because it's kind of slow so there's
enough time and therefore that flash to

11
00:00:43,510 --> 00:00:49,360
power up and fire but if the shutter
speed is too quick what ends up

12
00:00:49,360 --> 00:00:52,890
happening is the front curtain opens in
the record closes before the flashes a

13
00:00:52,890 --> 00:00:58,160
chance to power up and fire off this is
what we refer to as flash

14
00:00:58,160 --> 00:01:03,280
synchronization and the general kind of
limit for speed on flash synchronization

15
00:01:03,280 --> 00:01:08,530
is 1 200 of a second sometimes to be
safe haven keep it around 11 60 the

16
00:01:08,530 --> 00:01:14,070
second but in general you can go to one
202nd and the flash can still fire off

17
00:01:14,070 --> 00:01:18,580
at whatever power said he wanted to
within a period of the shutter speed

18
00:01:18,580 --> 00:01:24,110
anything above that and you run into
flash synchronization problems and what

19
00:01:24,110 --> 00:01:27,520
basically happened is let's say for
example using a pocket wizard on the

20
00:01:27,520 --> 00:01:31,869
camera unit itself and then using an
off-camera flash and I go at 1 400 of

21
00:01:31,869 --> 00:01:36,439
the second shutter speed when I fire I'm
gonna end up with a black bar in the

22
00:01:36,439 --> 00:01:40,820
frame where basically part of the flash
was able to fire before the rear curtain

23
00:01:40,820 --> 00:01:44,140
closed and then what we're seeing with
that black bar is actually the rear

24
00:01:44,140 --> 00:01:47,899
curtain so the record is closing before
the flash had a chance to completely

25
00:01:47,899 --> 00:01:52,630
fire so you'll see a bar going across
the image where / hit a certain portion

26
00:01:52,630 --> 00:01:57,840
and where missed another portion that
synchronization now generally when

27
00:01:57,840 --> 00:02:02,290
you're using a full-feature flash on
your hot shoe it's not going to allow

28
00:02:02,290 --> 00:02:06,530
you to go above 1 200 of a second
without turning on

29
00:02:06,530 --> 00:02:10,459
high-speed sync so automatically it
limits you their wares with a pocket is

30
00:02:10,459 --> 00:02:13,530
that it doesn't limit you can actually
take the the shutter speed up too high

31
00:02:13,530 --> 00:02:18,569
and run into the problem with a flash
with Apple TV flash it just limits your

32
00:02:18,569 --> 00:02:22,050
camera to actually not being able to go
about 12 seconds of you ever wonder why

33
00:02:22,050 --> 00:02:26,959
why is my camera not going about 100
seconds get your flashes on and you

34
00:02:26,959 --> 00:02:32,340
haven't turned on high-speed sync so we
have two options

35
00:02:32,340 --> 00:02:39,470
well if you're working outdoors in
midday Sun and you want to get your

36
00:02:39,470 --> 00:02:44,630
shutter speed slow enough for your flash
to fire you yourselves be below 12 in

37
00:02:44,630 --> 00:02:50,019
the second that means you're using an
aperture of say F 11 F fourteen to get

38
00:02:50,019 --> 00:02:54,400
that shutter speed slow enough to
synchronize your flash with that's a

39
00:02:54,400 --> 00:02:58,209
great if if you're working with a
background it's beautiful and you want

40
00:02:58,209 --> 00:03:01,540
the field anyone or show this entire
landscape and you want to highlight a

41
00:03:01,540 --> 00:03:04,730
subject in his background in everything
you want to be in focus that's fine

42
00:03:04,730 --> 00:03:05,920
that's great

43
00:03:05,920 --> 00:03:09,620
the problem is if you're working at
midday situation and you want to blur

44
00:03:09,620 --> 00:03:13,780
the background if you want to create
depth of field and separation there and

45
00:03:13,780 --> 00:03:17,620
you lower the after you open up the
absurd I guess they have to wait an F

46
00:03:17,620 --> 00:03:22,760
for well your shutter speed now climbs
up so you're such as PDF to have to wait

47
00:03:22,760 --> 00:03:27,230
is going to be around 12 thousandth of a
second one for dozens of a second and

48
00:03:27,230 --> 00:03:33,860
that's far too quick for standard
synchronization speed so what are two

49
00:03:33,860 --> 00:03:34,540
options

50
00:03:34,540 --> 00:03:38,790
well the two options basically either
use high-speed sync which is a feature

51
00:03:38,790 --> 00:03:44,390
built into full feature flashes that
allows the flash of fire even at higher

52
00:03:44,390 --> 00:03:49,660
shutter speeds than 12 in the second or
we use a neutral density filter which

53
00:03:49,660 --> 00:03:53,579
would have to buy separately this for
example is that neutral density filter

54
00:03:53,579 --> 00:03:57,350
this is a five stop singing a filter
that this is the filter that we prefer

55
00:03:57,350 --> 00:04:01,530
using cuz it's very nice and quality it
is rather expensive so we have some

56
00:04:01,530 --> 00:04:04,440
other suggestions that will be talking
about when it comes to any filters that

57
00:04:04,440 --> 00:04:10,250
are in different price ranges but what
the heck why would I recommend buying a

58
00:04:10,250 --> 00:04:13,670
neutral density filter why would I even
use a neutral density filter if I have a

59
00:04:13,670 --> 00:04:15,860
job that's built into my flash

60
00:04:15,860 --> 00:04:19,769
let's talk in detail of Ages first I
have my photo features plus which is

61
00:04:19,769 --> 00:04:24,810
a full-featured / right here and to get
to ages as I simply hit HSS on the back

62
00:04:24,810 --> 00:04:30,240
of the unit and I get to HSS now I could
carry my shutter speed up higher than 12

63
00:04:30,240 --> 00:04:34,180
under the second and the flash can fire
and synchronize between that shutter

64
00:04:34,180 --> 00:04:39,550
speed so that sounds pretty fantastic
right but here's what's actually

65
00:04:39,550 --> 00:04:45,789
happening once you go into HSS your
flash is no longer firing once when the

66
00:04:45,789 --> 00:04:49,759
shutter opens what's actually happening
and it looks like it's firing ones but

67
00:04:49,759 --> 00:04:54,599
what actually is happening is the
flashes pulsing so the flash within that

68
00:04:54,599 --> 00:04:58,690
shattered that it opened up with enough
speed let's say 1 500 second one one

69
00:04:58,690 --> 00:05:03,949
thousandth of a second the flashes gonna
fire multiple times as fast as it

70
00:05:03,949 --> 00:05:10,659
possibly can to make sure that it
basically fits in there a flash ok so it

71
00:05:10,659 --> 00:05:18,169
might / 20 times at within that 1 501
1,000 per 1,000 part of a second fired

72
00:05:18,169 --> 00:05:22,030
multiple times and it looks like one
class what's happened so fast but

73
00:05:22,030 --> 00:05:25,620
actually post to make sure that one of
those with able to get into that

74
00:05:25,620 --> 00:05:33,580
synchronization speed now as you can
imagine if it's firing 5 10 20 50 times

75
00:05:33,580 --> 00:05:36,750
within that fraction of a second

76
00:05:36,750 --> 00:05:40,960
well you're probably losing flash power
right because they can't fire at full

77
00:05:40,960 --> 00:05:47,110
power that many times in that little
shorter period has to be cycle so we

78
00:05:47,110 --> 00:05:51,240
have tremendous amount of light loss how
much like loss in general when you're

79
00:05:51,240 --> 00:05:55,560
using high-speed sync you're gonna be
shooting at around four to five stops

80
00:05:55,560 --> 00:05:58,110
below full power

81
00:05:58,110 --> 00:06:03,449
ok so we're only getting like say three
to five percent of our total flash

82
00:06:03,449 --> 00:06:09,580
output when we're in high-speed sync
modes now it still is usable but the

83
00:06:09,580 --> 00:06:12,580
thing there is that you have a lot of
compromise that you have to make when

84
00:06:12,580 --> 00:06:16,080
you're using high-speed saying let's say
for example with this image right here

85
00:06:16,080 --> 00:06:22,289
this was shot at 14 under the second
half to an ISO 50 so to get down to one

86
00:06:22,289 --> 00:06:26,849
four hundred a second even the drama is
so than 250 which on the 5d Mark III is

87
00:06:26,849 --> 00:06:30,250
not a native ISO some actually
compromising a little bit of dynamic

88
00:06:30,250 --> 00:06:30,630

34
00:02:26959——> 00:02:32340

00:04:10250——> 00:04:13670
中性密度滤光片为什么我甚至
使用中性密度滤光片如果我有一个

67
00:04:49759——> 00:04:54599
那确实发生的事情是
闪烁脉冲在这

68
00:04:54599——> 00:04:58690
破碎，它开辟了足够的
速度让我们说1 500秒一一

00:04:58690——> 00:05:03949
第一千秒闪烁会
火多倍

70
00:05:03949——> 00:05:10659
可能可以确保它

71
00:05:10659——> 00:05:18169
可能/ 20次在1 501
1000每1000部分的第二发射

00:05:18169——> 00:05:22030
多次，它看起来像一个
班什么的发生得如此之快，但

73
00:05:22030——> 00:05:25620
其实后确保一个
