100:00:02,670 --> 00:00:05,740in th

1
00:00:02,670 --> 00:00:05,740
in the previous segment we saw that a
luminosity selection

2
00:00:05,740 --> 00:00:08,960
is a selection based on the luminosity
values within the image

3
00:00:08,960 --> 00:00:12,059
but I find that knowing what a
luminosity selection is

4
00:00:12,059 --> 00:00:15,749
just makes me think a behold much new
questions curfew

5
00:00:15,749 --> 00:00:21,599
how do you make a luminosity selection
what exactly is being selected

6
00:00:21,599 --> 00:00:26,660
once a luminosity selection is made how
does become a luminosity mask

7
00:00:26,660 --> 00:00:32,259
and is a luminosity selection like any
other selection but explore these

8
00:00:32,259 --> 00:00:33,450
questions one at a time

9
00:00:33,450 --> 00:00:36,470
how do you make a luminosity selection

10
00:00:36,470 --> 00:00:40,680
as with all things in Photoshop there
are multiple ways to accomplish the same

11
00:00:40,680 --> 00:00:41,450
result

12
00:00:41,450 --> 00:00:45,800
I'll show you two ways making a
luminosity selection one is to hold down

13
00:00:45,800 --> 00:00:46,890
the Control key

14
00:00:46,890 --> 00:00:50,200
or the command key on a Mac and then
click

15
00:00:50,200 --> 00:00:53,570
on the channel from which you want to
make the selection in this case

16
00:00:53,570 --> 00:00:57,030
the RGB channel I can also make a
selection

17
00:00:57,030 --> 00:01:00,950
from the red channel where the green
channel for the blue channel

18
00:01:00,950 --> 00:01:05,339
by holding down the control or command
key and clicking on the channel

19
00:01:05,339 --> 00:01:09,350
the other way to make a luminosity
selection

20
00:01:09,350 --> 00:01:13,740
is to highlight the channel that you
want to make the selection from

21
00:01:13,740 --> 00:01:17,700
and then click the load channel as
selection icon at the bottom of the

22
00:01:17,700 --> 00:01:18,540
channels panel

23
00:01:18,540 --> 00:01:22,570
for the red channel

24
00:01:22,570 --> 00:01:27,530
the green channel and the blue channel

25
00:01:27,530 --> 00:01:35,330
or the RGB channel either method you use
creates the same selected area as

26
00:01:35,330 --> 00:01:36,990
indicated by the marching ants

27
00:01:36,990 --> 00:01:40,420
if you aren't familiar with the term our
chance it's what we call the moving

28
00:01:40,420 --> 00:01:41,830
dotted lines outlines

29
00:01:41,830 --> 00:01:45,860
elections in Photoshop what exactly is
being selected

30
00:01:45,860 --> 00:01:50,060
a lot of marching ants appear on the
screen when a luminosity selection is

31
00:01:50,060 --> 00:01:50,479
made

32
00:01:50,479 --> 00:01:53,790
but it can be difficult to determine
exactly what has been selected

33
00:01:53,790 --> 00:01:58,080
tony and I find that using a ton
gradient is invaluable in helping us

34
00:01:58,080 --> 00:01:58,810
determine

35
00:01:58,810 --> 00:02:03,490
which luminosity values are included in
a selection to make a ton gradient start

36
00:02:03,490 --> 00:02:10,829
by creating a new white image document
it can be any size but 1000 pixels on

37
00:02:10,829 --> 00:02:14,030
the long side should fit well in most
screens

38
00:02:14,030 --> 00:02:18,300
for the color settings choose the RGB
color mode and it probably doesn't

39
00:02:18,300 --> 00:02:21,570
make too much difference but also select
the 16 bit depth

40
00:02:21,570 --> 00:02:28,410
to make sure that I have a smooth tonal
greedy now select a gradient tool

41
00:02:28,410 --> 00:02:32,730
set the foreground color to white and
the background color to black

42
00:02:32,730 --> 00:02:37,200
and now drag a gradient from one side

43
00:02:37,200 --> 00:02:40,830
the white image to the other side

44
00:02:40,830 --> 00:02:44,550
and the greedy all be created

45
00:02:44,550 --> 00:02:50,100
this is a document that contains all up
the luminosity values from pure white

46
00:02:50,100 --> 00:02:54,450
to cure black with very smooth gradient
have

47
00:02:54,450 --> 00:02:59,200
shades agree in between I recommend that
you create and save your own tone

48
00:02:59,200 --> 00:03:02,320
gradient to help you better visualize
luminosity selections

49
00:03:02,320 --> 00:03:05,700
you can save it has a to file or a PST
file

50
00:03:05,700 --> 00:03:09,650
collette Andrea and then open it up
whenever you want to visualize a

51
00:03:09,650 --> 00:03:10,950
luminosity selection

52
00:03:10,950 --> 00:03:15,410
now let's make a luminosity selection
the RGB channel

53
00:03:15,410 --> 00:03:19,380
up this greedy some hold down the
controller command key

54
00:03:19,380 --> 00:03:26,110
and click on the RGB channel you can
clearly see that is the lightest portion

55
00:03:26,110 --> 00:03:26,970
of the gradient

56
00:03:26,970 --> 00:03:30,430
that has been selected so it appears
that we are selecting the brightest

57
00:03:30,430 --> 00:03:32,310
luminosity values in the image

58
00:03:32,310 --> 00:03:35,360
Tony calls this initial in a nasty
selection

59
00:03:35,360 --> 00:03:40,950
above the brightest towns delights
selection because half the latest towns

60
00:03:40,950 --> 00:03:41,700
are selected

61
00:03:41,700 --> 00:03:46,930
I often refer to this as a fifty-percent
light selection but returned to our

62
00:03:46,930 --> 00:03:47,790
color image

63
00:03:47,790 --> 00:03:51,170
now I can see that the marching ants

64
00:03:51,170 --> 00:03:55,130
are indicating that the brightest
luminosity values in this image

65
00:03:55,130 --> 00:03:59,100
are selected 12 luminosity selection is
made

66
00:03:59,100 --> 00:04:03,860
how does become a luminosity mask let's
start by D selecting

67
00:04:03,860 --> 00:04:07,120
this current selection in Photoshop

68
00:04:07,120 --> 00:04:10,980
if you first make a selection like I did
previously when I use the quick

69
00:04:10,980 --> 00:04:12,019
selection tool

70
00:04:12,019 --> 00:04:19,890
to select the sky

71
00:04:19,890 --> 00:04:22,080
and then generate a new white mask

72
00:04:22,080 --> 00:04:26,100
for example when I create a Curves
adjustment layer as long as the

73
00:04:26,100 --> 00:04:28,250
selection was active when the mask was
made

74
00:04:28,250 --> 00:04:33,820
the mask will reflect the selection in
the mask the area inside the selection

75
00:04:33,820 --> 00:04:34,560
will be white

76
00:04:34,560 --> 00:04:38,980
revealing any adjustment made on that
layer and the area outside the selection

77
00:04:38,980 --> 00:04:39,860
will be black

78
00:04:39,860 --> 00:04:44,510
concealing any adjustments made on that
where luminosity selections are no

79
00:04:44,510 --> 00:04:45,940
different in this respect

80
00:04:45,940 --> 00:04:55,190
if you have a luminosity selection
active and then generate a new mask

81
00:04:55,190 --> 00:05:00,020
the mask will reflect the selection

82
00:05:00,020 --> 00:05:06,360
is a luminosity selection like any other
selection

83
00:05:06,360 --> 00:05:10,640
this is where masked men from luminosity
selection show their true worth

84
00:05:10,640 --> 00:05:14,740
the manassas elections are not by an
eerie like more simple selections

85
00:05:14,740 --> 00:05:17,780
that is to say that the pixels on a
luminosity selection

86
00:05:17,780 --> 00:05:21,430
are not either one hundred percent
selected or 100 percent

87
00:05:21,430 --> 00:05:24,590
not selected resulting in a pure white
and black mask

88
00:05:24,590 --> 00:05:27,810
to view a mask hold the Alt key

89
00:05:27,810 --> 00:05:31,260
or the Option key on a Mac and click to
mask thumbnail

90
00:05:31,260 --> 00:05:34,260
when we view the mask

91
00:05:34,260 --> 00:05:38,840
the original sky selection that we made
we can see that it is very simple

92
00:05:38,840 --> 00:05:42,760
all white or all black mask but when we
view the mask

93
00:05:42,760 --> 00:05:47,870
generated from the luminosity selection
we can see that it is a very different

94
00:05:47,870 --> 00:05:50,000
and very highly detailed mask

95
00:05:50,000 --> 00:05:54,890
now consider every pixel in the image
was actually selected somewhere between

96
00:05:54,890 --> 00:05:56,070
zero percent

97
00:05:56,070 --> 00:06:00,400
and a hundred percent based on its
luminosity 10 per cent being black in

98
00:06:00,400 --> 00:06:01,100
the mask

99
00:06:01,100 --> 00:06:05,200
100 per cent being white in the mask and
every other to grieve luminosity being

100
00:06:05,200 --> 00:06:06,390
partially selected

101
00:06:06,390 --> 00:06:10,020
the resulting in different shades of
grey so

102
00:06:10,020 --> 00:06:14,860
if every pixel other than pure black is
partially selected to some degree

103
00:06:14,860 --> 00:06:26,160
what did the marching ants in a
luminosity selection actually show us

104
00:06:26,160 --> 00:06:29,360
they're showing us regions in the image
in which the pixels are at least 50

105
00:06:29,360 --> 00:06:30,700
percent selected

106
00:06:30,700 --> 00:06:34,950
in the case at this current lights
selection the ants were drawn around

107
00:06:34,950 --> 00:06:38,680
a reserve the image in which the pixels
had a total value abruptly

108
00:06:38,680 --> 00:06:42,140
50 percent gray or lighter and therefore

109
00:06:42,140 --> 00:06:49,780
there at least 50 percent or more
selected

110
00:06:49,780 --> 00:06:52,960
now that we know how to make a basic
lights luminosity selection

111
00:06:52,960 --> 00:06:57,050
and then create a mask using that
selection let's find out what it would

112
00:06:57,050 --> 00:06:59,530
look like to make an adjustment using
the mask

113
00:06:59,530 --> 00:07:02,900
steady this image I'm gonna go to a
different image

114
00:07:02,900 --> 00:07:07,200
that has a little more contrast the
light it'll make a luminosity mass a

115
00:07:07,200 --> 00:07:07,830
little more

116
00:07:07,830 --> 00:07:11,700
obvious apparent before we go to
Amanda's the mask adjustment let's just

117
