100:00:00,000 --> 00:00:03,520in th

1
00:00:00,000 --> 00:00:03,520
in this video we're gonna go over the
light meter in detail and this is why we

2
00:00:03,520 --> 00:00:06,850
know basically how to adjust our
exposure we can adjust our exposure with

3
00:00:06,850 --> 00:00:11,450
their shutter speed aperture ISO but how
do we essentially know where to start

4
00:00:11,450 --> 00:00:15,160
out with i mean how do we get that first
exposure to be roughly where we wanted

5
00:00:15,160 --> 00:00:18,580
to be so we need to do is we need to
understand how that light meter works

6
00:00:18,580 --> 00:00:22,570
and then we need to adjust according to
it and then get are correct exposure now

7
00:00:22,570 --> 00:00:25,539
let me go ahead and show you what I mean
is that of talking through it okay we're

8
00:00:25,539 --> 00:00:29,490
gonna hit the Live View button right now
so we can get our screen just a show up

9
00:00:29,490 --> 00:00:33,890
here so go ahead and hit the LabVIEW and
right now you can see the screen is

10
00:00:33,890 --> 00:00:37,980
actually extremely dark we can't really
see anything so the first thing to do is

11
00:00:37,980 --> 00:00:41,980
actually go down to an absurd that I
want for the overall scene I think for

12
00:00:41,980 --> 00:00:46,210
this scene it look really beautiful at
around f2f 2.8 that's the first thing to

13
00:00:46,210 --> 00:00:49,360
do I'm gonna just my aperture based on
the overall composition and I'm going

14
00:00:49,360 --> 00:00:54,120
for ok so let's go ahead and just gonna
have to point to point out so right now

15
00:00:54,120 --> 00:00:57,649
you can see that the exposure based on
his live view exposure preview is

16
00:00:57,649 --> 00:01:01,489
actually pretty close to where we want
to be now say that the shutter speed is

17
00:01:01,489 --> 00:01:05,280
kind of high let's say that we're at one
one thousandth of a second well that the

18
00:01:05,280 --> 00:01:08,409
camera itself is going to basically give
me a reading on that light meter you can

19
00:01:08,409 --> 00:01:11,670
see this light meter at the bottom of
the screen the light meter generally is

20
00:01:11,670 --> 00:01:14,710
going to range from negative to or
negative three stops right now we have

21
00:01:14,710 --> 00:01:17,130
negative three stops on this camera all
the way up to

22
00:01:17,130 --> 00:01:20,970
plus three stops right in the middle
where that little arrow is or where it's

23
00:01:20,970 --> 00:01:25,310
20 that is what the camera is telling
you is that technically correct exposure

24
00:01:25,310 --> 00:01:29,780
we've already gone over basically talked
about how well exposures are really

25
00:01:29,780 --> 00:01:33,710
about the artistry so different types of
exposures really just matters on the

26
00:01:33,710 --> 00:01:35,979
scene where they're going for something
bright and airy whether you going to

27
00:01:35,979 --> 00:01:38,479
something a little more dark and
dramatic it doesn't matter so long as

28
00:01:38,479 --> 00:01:42,579
you shoot the correct exposure for what
you're going to artistically so kind of

29
00:01:42,579 --> 00:01:45,659
take what it's saying what that camera
saying is that technically correct

30
00:01:45,659 --> 00:01:49,000
exposure just as a grain of salt is
telling you this is what it thinks is

31
00:01:49,000 --> 00:01:52,270
technically correct based on the
metering mode you're using we're gonna

32
00:01:52,270 --> 00:01:56,219
talk about metering modes in a follow-up
video but to the left of that little

33
00:01:56,219 --> 00:01:59,590
meter we know that it's under exposed
and to the right of that meter we know

34
00:01:59,590 --> 00:01:59,840
it

35
00:01:59,840 --> 00:02:03,590
overexposed and in the middle that's
worth telling you its second correct

36
00:02:03,590 --> 00:02:06,979
case let's go ahead and as I bring my
shutter speed up your gonna see that

37
00:02:06,979 --> 00:02:10,929
little meters gonna keep pulling to the
left now won four thousand the second

38
00:02:10,929 --> 00:02:14,160
that's actually the shutter limitation
on this camera we're always negative

39
00:02:14,160 --> 00:02:18,860
three stops now if I go in I raised the
aperture it can't really go down any

40
00:02:18,860 --> 00:02:22,400
further so what you see is a little tiny
arrow that points to the left of three

41
00:02:22,400 --> 00:02:25,989
stops some cameras only go to negative
two stops on the bus to you and the

42
00:02:25,989 --> 00:02:29,660
negative to side if you see that arrow
that kind of saying its way off to the

43
00:02:29,660 --> 00:02:33,110
side will you need to make some
adjustments before your meter is going

44
00:02:33,110 --> 00:02:36,680
to appear within that little light
metering range so we're gonna do it just

45
00:02:36,680 --> 00:02:39,700
make that adjustment real quick to get
our meter back and then go back to F two

46
00:02:39,700 --> 00:02:44,540
we're gonna go ahead and slow down the
shutter and if I just halfway to press

47
00:02:44,540 --> 00:02:47,819
the shutter release button our little
light meter pasa backup on the display

48
00:02:47,819 --> 00:02:51,650
and I can see it again so right now I'm
at negative to stop so I know that if I

49
00:02:51,650 --> 00:02:56,040
want to add just be my shutter speed
while min ago one-stop up where no one

50
00:02:56,040 --> 00:03:03,420
1001 stop underexposed and I go to 1 501
502 second and a half to and iso 100

51
00:03:03,420 --> 00:03:07,549
this is where the cameras tell me this
is a technically correct exposure for

52
00:03:07,549 --> 00:03:11,400
the scene but I still need to judge for
myself and that's where I really am

53
00:03:11,400 --> 00:03:15,100
going to use things like my histogram we
can see from this view right here that

54
00:03:15,100 --> 00:03:19,109
the histogram is a little bit pulled to
the shadow side so I might do is click

55
00:03:19,109 --> 00:03:23,790
down I will go to one four hundred
second this is where I'm gonna say is my

56
00:03:23,790 --> 00:03:27,680
correct exposure brighter tone is going
to yield a better picture is going to be

57
00:03:27,680 --> 00:03:31,319
a more flattering skin tones so so as
not blowing everything out I'm getting

58
00:03:31,319 --> 00:03:35,260
what I want I want to err on the side of
brighter for this type of a scene

59
00:03:35,260 --> 00:03:39,200
all right quick general tips cuz you
nope I just mentioned a very important

60
00:03:39,200 --> 00:03:44,669
note that I want to briefly emphasized
he said so long as you aren't blowing

61
00:03:44,669 --> 00:03:49,180
anything out you want to err on the
brighter site so this technique is known

62
00:03:49,180 --> 00:03:54,010
as et TR or exposing to the right

63
00:03:54,010 --> 00:03:59,269
histogram now this doesn't mean that you
blow out your highlights but rather that

64
00:03:59,269 --> 00:04:04,700
you will get a cleaner image if you
exposed to highlights then ETTL or

65
00:04:04,700 --> 00:04:09,680
exposed to the left which would make the
image darker so rule of thumb when you

66
00:04:09,680 --> 00:04:15,580
want to maximize tonal range in a shot
and maximize image quality ETR

67
00:04:15,580 --> 00:04:19,560
exposed to that you're peter is pushed
as far to the right without actually

68
00:04:19,560 --> 00:04:24,270
blowing out any highlights and without
clicking any shadows ok so back to the

69
00:04:24,270 --> 00:04:28,180
video before right now this looks great
when I'm gonna do is drop the camera off

70
00:04:28,180 --> 00:04:31,310
and we're going to take our shot the one
thing I'm gonna do here though is I am

71
00:04:31,310 --> 00:04:34,320
gonna add a little bit of a feel like
I'm not sure exactly what that's going

72
00:04:34,320 --> 00:04:39,730
to do so if you want to grab the silver
Hill so what we're doing here is we're
