100:00:00,000 --> 00:00:03,030as we

1
00:00:00,000 --> 00:00:03,030
as we progress through the photography
101 series we're gonna be teaching you

2
00:00:03,030 --> 00:00:07,129
all sorts of ways that you can use the
cameras in camera metering system to

3
00:00:07,129 --> 00:00:10,580
basically measure the amount of light
around you but for right now we don't

4
00:00:10,580 --> 00:00:13,450
want to get into all the technical stuff
I want you all to get out shooting with

5
00:00:13,450 --> 00:00:17,510
us and we understand what we're doing in
camera so what I want to do is teach you

6
00:00:17,510 --> 00:00:22,260
how to gauge exposure using Live View
and using the Live View histogram the

7
00:00:22,260 --> 00:00:26,640
histogram is an incredibly powerful tool
to help us to visually gauge the overall

8
00:00:26,640 --> 00:00:31,019
exposure in our images and when to use
this scene to demonstrate now what we

9
00:00:31,019 --> 00:00:34,520
have here is we have the Sun directly in
front of me right now it is behind some

10
00:00:34,520 --> 00:00:38,370
clouds so it is softened up a little bit
but it's basically right behind the

11
00:00:38,370 --> 00:00:42,129
scene that I'm shooting into this means
that the seat is going to be backlit so

12
00:00:42,129 --> 00:00:46,010
in the rocks we have very deep and dark
shadows in the water we have a very

13
00:00:46,010 --> 00:00:50,010
bright highlights where the light from
the Sun is touching this is going to be

14
00:00:50,010 --> 00:00:52,840
kind of difficult when we get to
exposing the scene correctly in the

15
00:00:52,840 --> 00:00:56,329
histogram is gonna be a powerful tool
now we don't have that necessarily when

16
00:00:56,329 --> 00:00:59,270
we're shooting with the Sun you can see
kind of behind me as we're shooting with

17
00:00:59,270 --> 00:01:03,199
the Sun everything kind of falls to a
very flat mid tone range because it's

18
00:01:03,199 --> 00:01:07,030
all being directly led to show you
exactly how this would look like in the

19
00:01:07,030 --> 00:01:10,260
history of but first let's pull apart
live you and show you exactly how you do

20
00:01:10,260 --> 00:01:15,780
it I have my Canon Rebel t2i by right
here on my tripod we have the 55 to 250

21
00:01:15,780 --> 00:01:19,310
lens on this is a standard kit lens and
we're going to is going to shoot a nice

22
00:01:19,310 --> 00:01:22,659
load composition giving us some
foreground rocks and shooting these tide

23
00:01:22,659 --> 00:01:25,780
pool rocks and getting a little bit of
water splashing on the water's coming in

24
00:01:25,780 --> 00:01:29,290
from the right side so you got a nice
shot is a water kind of comes up and

25
00:01:29,290 --> 00:01:33,740
give us a nice action shots we have this
amounted to Army photo globetrotter

26
00:01:33,740 --> 00:01:38,060
tripod it's a great tripod and expensive
for what you get is pretty awesome I'm

27
00:01:38,060 --> 00:01:41,350
gonna mounted just that everything stays
stable as we're demonstrating all these

28
00:01:41,350 --> 00:01:44,439
different things and we can see exactly
from frame to frame how it looks let's

29
00:01:44,439 --> 00:01:47,329
go ahead and hit the Live View button
right are eighty-five I here and gonna

30
00:01:47,329 --> 00:01:51,000
pull up our live you on the back of the
screen now right now I pretty much don't

31
00:01:51,000 --> 00:01:55,250
see anything okay because it's too dark
and underexposed completely so we need

32
00:01:55,250 --> 00:01:58,070
to do is that just exposure so at least
we see something on the back of the

33
00:01:58,070 --> 00:02:01,659
screen now typically here live use
prominent display something more like

34
00:02:01,659 --> 00:02:05,500
along the lines of this now to get it to
display the history and we simply hit

35
00:02:05,500 --> 00:02:09,000
info until the histogram actually
displayed now let's go ahead and adjust

36
00:02:09,000 --> 00:02:10,649
our shutter speed or aperture

37
00:02:10,649 --> 00:02:14,090
gonna go with first of all and after a
maybe a little bit lower than hold down

38
00:02:14,090 --> 00:02:17,280
the option button we're gonna go down
like maybe around eight because I do

39
00:02:17,280 --> 00:02:21,150
want a broad depth of field I want to
get around that optimal sharpness on the

40
00:02:21,150 --> 00:02:24,260
aperture as well and I now I'm gonna
slow down the shutter just so we have

41
00:02:24,260 --> 00:02:29,140
something to see on the screen now this
info so we can bring up that live you

42
00:02:29,140 --> 00:02:32,890
histogram and there it is now the
histogram looks a little bit confusing

43
00:02:32,890 --> 00:02:36,430
and it looks something like awful that
we used to hate in mathematics with

44
00:02:36,430 --> 00:02:39,510
those curves and all that but it's
really not that hard to understand and

45
00:02:39,510 --> 00:02:43,269
it's very simple when you know exactly
what I showing you all the histogram is

46
00:02:43,269 --> 00:02:46,709
doing is showing you the overall
brightness or the luminosity and you're

47
00:02:46,709 --> 00:02:50,129
seeing now what this means is that the
left of the histogram this little side

48
00:02:50,129 --> 00:02:53,590
over here on the left is going to be our
shadows in the middle we have our mid

49
00:02:53,590 --> 00:02:57,540
tone and in the right side we have our
highlights anything that's pushed into

50
00:02:57,540 --> 00:03:00,349
those areas based is gonna be
demonstrated with these peaks now

51
00:03:00,349 --> 00:03:04,959
wherever it peaks at telling you that a
lot of the tonal range in the image is

52
00:03:04,959 --> 00:03:08,159
in that area in your shopping going to
show exactly that means I'm sure that

53
00:03:08,159 --> 00:03:11,970
was very confusing to hear so right now
we're a little bit underexposed let me

54
00:03:11,970 --> 00:03:15,250
go ahead and keep under exposing and
what you're gonna see is that when I get

55
00:03:15,250 --> 00:03:19,699
up to 14 thousandth of a second at a
title 100 everything is pushed to the

56
00:03:19,699 --> 00:03:24,510
left of the histogram showing that it's
under expose everything push the left me

57
00:03:24,510 --> 00:03:28,510
that work clipping our shadow detail if
we are losing shadow detail that means

58
00:03:28,510 --> 00:03:32,040
it's gone it doesn't matter for shooting
RAW and JPEG it is gone when we get into

59
00:03:32,040 --> 00:03:35,940
post-production its gonna print as pure
black likewise it hard to bring this all

60
00:03:35,940 --> 00:03:38,639
the way to the other side so now I'm
slowing down the shutter speed going

61
00:03:38,639 --> 00:03:42,359
down to one one-hundredth of a second
now we push everything to the right side

62
00:03:42,359 --> 00:03:45,409
of the histogram so everything is pushed
against the right side are shadows come

63
00:03:45,409 --> 00:03:49,209
off the left edge so we have very little
showers in the scene and we have a lot

64
00:03:49,209 --> 00:03:52,940
of highlight that are being blown out
blown out at the same thing as flipping

65
00:03:52,940 --> 00:03:55,819
are shadows we're losing our detail in
our highlights and that means those

66
00:03:55,819 --> 00:03:59,500
highlights are going to print as pure
white the goal of the histogram is to

67
00:03:59,500 --> 00:04:03,400
get everything within the middle range
basically what we're gonna do is adjust

68
00:04:03,400 --> 00:04:08,030
my shutter speed and watch visually as
the histogram pulls into the center now

69
00:04:08,030 --> 00:04:11,840
the goal is to get our shadows up
against the left edge and the highlights

70
00:04:11,840 --> 00:04:15,229
up against the right now without blowing
out any highlights and without clipping

71
00:04:15,229 --> 00:04:16,549
any of our shadows

72
00:04:16,549 --> 00:04:21,259
and we get that right around say one to
be the second right now now we can get

73
00:04:21,259 --> 00:04:24,430
that right now because well we're not
getting two hearts of sunlight we're

74
00:04:24,430 --> 00:04:28,069
covered and cloud cover but if it were
much brighter if there were no cloud

75
00:04:28,069 --> 00:04:31,629
then we'd have to go with a much higher
shutter speed so that is a balanced

76
00:04:31,629 --> 00:04:35,879
histogram now once I have that I'm just
gonna wait for my waves and then take my

77
00:04:35,879 --> 00:04:42,409
shot now I'm noticing that I'm not one
to be the second that means that we are

78
00:04:42,409 --> 00:04:46,370
going to be showing a little bit the
action in the way that motion were not

79
00:04:46,370 --> 00:04:49,629
be fully freezing it so what I'm I want
to do is just a just might have turned

80
00:04:49,629 --> 00:04:53,509
down a little bit so I'm gonna bring my
absurd down to let's say seven point

81
00:04:53,509 --> 00:04:57,650
actually gonna 6.3 will bring the
shutter speed up to 1 500 per second so

82
00:04:57,650 --> 00:05:01,030
we can freeze that water is just a
little bit better now all going to come

83
00:05:01,030 --> 00:05:05,099
down to is waiting for that perfect wave
and capturing our shot by the way I have

84
00:05:05,099 --> 00:05:08,159
locked in my focus I just picked up a
point of focus that kind of in the

85
00:05:08,159 --> 00:05:12,389
middle of our depth and that seemed
locked out focus right there is that way

86
00:05:12,389 --> 00:05:15,590
doesn't change throughout this entire
scene I did that is by switching system
