1
00:00:03,030 --> 00:00:06,490
one of the more difficult aspects
abusing luminosity masks is knowing

2
00:00:06,490 --> 00:00:10,769
which mask to use for any particular
adjustment says every image in every

3
00:00:10,769 --> 00:00:14,980
adjustment is different there is no
right answer to this question selecting

4
00:00:14,980 --> 00:00:17,529
the right mask for your needs takes a
lot of practice

5
00:00:17,529 --> 00:00:21,609
trial and error don't be afraid to get
creative experiment and find out what

6
00:00:21,609 --> 00:00:22,569
works and what doesn't

7
00:00:22,569 --> 00:00:25,989
I usually begin by identifying two
factors

8
00:00:25,989 --> 00:00:30,319
what part of the image do I want to
adjust and what type adjustment do I

9
00:00:30,319 --> 00:00:31,189
want to make

10
00:00:31,189 --> 00:00:35,280
17 answer these two questions I'm ready
to select a mask

11
00:00:35,280 --> 00:00:39,160
with practice you may be able to predict
which mask will work for

12
00:00:39,160 --> 00:00:44,070
any given adjustment however even after
years of working with luminosity masks

13
00:00:44,070 --> 00:00:47,520
I find it is helpful to generate an
entire series masks

14
00:00:47,520 --> 00:00:51,060
in the channels panel and then compare
them with each other help me make the

15
00:00:51,060 --> 00:00:51,920
right selection

16
00:00:51,920 --> 00:00:56,160
in this image let's say I decided I
would like to adjust the brightness

17
00:00:56,160 --> 00:01:00,210
the brightest portions at the sky I
would begin by generating all the lights

18
00:01:00,210 --> 00:01:00,780
mask

19
00:01:00,780 --> 00:01:09,539
using the TK Actions panel now I can
look at each mask individually to see

20
00:01:09,539 --> 00:01:10,710
which one shows white

21
00:01:10,710 --> 00:01:14,659
or light grey in the areas I want to
adjust and black or dark gray in the

22
00:01:14,659 --> 00:01:16,469
areas that I do not want to adjust

23
00:01:16,469 --> 00:01:19,549
I can tell by looking at the small
thumbnails action click on each

24
00:01:19,549 --> 00:01:21,479
luminosity channel one at a time

25
00:01:21,479 --> 00:01:29,480
to get the full preview

26
00:01:29,480 --> 00:01:32,560
I think the lights lights mask looks
like 21

27
00:01:32,560 --> 00:01:35,920
that target stares at the sky that I
really want to work on

28
00:01:35,920 --> 00:01:39,590
so I'll choose the next more restrictive
mask the bright lights

29
00:01:39,590 --> 00:01:43,310
the reason for going to the next more
restrictive mask is to prevent the

30
00:01:43,310 --> 00:01:46,340
adjustment from bleeding and areas that
you don't want to change

31
00:01:46,340 --> 00:01:50,730
the cell feathering nature of the mask
can cause more adjustment in unintended

32
00:01:50,730 --> 00:01:52,230
areas than expected

33
00:01:52,230 --> 00:01:55,760
by using a slightly more restrictive
mask you better able to constrain the

34
00:01:55,760 --> 00:01:57,790
adjustment to the party the image that
you want

35
00:01:57,790 --> 00:02:02,440
at this point I can control or comment
click on the channel I want to select

36
00:02:02,440 --> 00:02:06,130
with the selection active

37
00:02:06,130 --> 00:02:09,350
a click on the RGB channel to go back to
my color image

38
00:02:09,350 --> 00:02:12,930
and then create an adjustment layer in
this case

39
00:02:12,930 --> 00:02:18,840
curves adjustment layer Tulare comes
with the appropriate luminosity mask

40
00:02:18,840 --> 00:02:24,560
attached I would name this layer bright
lights

41
00:02:24,560 --> 00:02:28,220
to accomplish the same task even faster

42
00:02:28,220 --> 00:02:31,260
I could just use the TK Actions panel to

43
00:02:31,260 --> 00:02:40,010
create a Curves adjustment layer above
the bright lights

44
00:02:40,010 --> 00:02:43,590
as you can see with 1-click I was able
to generate the exact same curves

45
00:02:43,590 --> 00:02:44,530
adjustment layer

46
00:02:44,530 --> 00:02:49,190
with the bright lights luminosity mask
attached I will point out however that

47
00:02:49,190 --> 00:02:49,930
using

48
00:02:49,930 --> 00:02:53,120
ETKA Actions panel to generate masks and

49
00:02:53,120 --> 00:02:57,420
adjustment layers when you already have
Manasi channels in the channels panel

50
00:02:57,420 --> 00:03:01,980
can cause the existing luminosity
channels to get out of order

51
00:03:01,980 --> 00:03:05,670
as you can see now the lights light
light and bright lights got moved to the

52
00:03:05,670 --> 00:03:07,340
bottom of the channel spell

53
00:03:07,340 --> 00:03:12,750
as an aside remember that if your
channels panel ever becomes

54
00:03:12,750 --> 00:03:15,760
too disorganized were too cluttered with
extra channels

55
00:03:15,760 --> 00:03:19,670
that you can shift click on each
luminosity channel

56
00:03:19,670 --> 00:03:26,640
to selected and then click on the trash
button to delete those channels

57
00:03:26,640 --> 00:03:30,740
and then with TK Actions panel

58
00:03:30,740 --> 00:03:34,020
you can quickly rebuild and organize set

59
00:03:34,020 --> 00:03:42,010
a luminosity masks we only need one
bright light adjustment layer

60
00:03:42,010 --> 00:03:43,760
psychiatric disorders trash

61
00:03:43,760 --> 00:03:47,220
I can open up the curves dialogue

62
00:03:47,220 --> 00:03:50,310
and I can pull the curve down

63
00:03:50,310 --> 00:03:59,350
to darken the image through the mask
because they use a more restrictive

64
00:03:59,350 --> 00:04:00,570
bright lights mask

65
00:04:00,570 --> 00:04:04,840
I can make a fairly aggressive
adjustment in more recent versions of

66
00:04:04,840 --> 00:04:05,860
Photoshop CS

67
00:04:05,860 --> 00:04:09,220
I can use the contextual adjustment tool
to adjust

68
00:04:09,220 --> 00:04:15,390
the curve by clicking and dragging on
the image itself another technique I

69
00:04:15,390 --> 00:04:16,280
like to use

70
00:04:16,280 --> 00:04:19,549
with a Curves adjustment layer is too
dark and

71
00:04:19,549 --> 00:04:24,310
with the multiply blending mode the
stark and the image you the mask but

72
00:04:24,310 --> 00:04:25,790
leaves the curve unaffected

73
00:04:25,790 --> 00:04:28,919
and I can use the curve to adjust
overall

74
00:04:28,919 --> 00:04:33,750
contrast as I feel is needed so here's
what the image looks like

75
00:04:33,750 --> 00:04:41,290
for the adjustment and after and it's
always interesting to shift click

76
00:04:41,290 --> 00:04:45,530
on the mask itself to see what the
adjustment would look like without the

77
00:04:45,530 --> 00:04:54,119
luminosity mask

78
00:04:54,119 --> 00:04:59,389
as you can see without the mask that's a
pretty severe adjustment I can see that

79
00:04:59,389 --> 00:05:02,659
this adjustment had its greatest effect
in the portions of the image that I

80
00:05:02,659 --> 00:05:03,469
intended

81
00:05:03,469 --> 00:05:07,159
and the adjustment perfectly feathers
itself but no halos are visible edges

82
00:05:07,159 --> 00:05:08,469
because the mask isn't

83
00:05:08,469 --> 00:05:12,830
a simple black and white mask or even a
mask made with a soft edge brush

84
00:05:12,830 --> 00:05:18,869
it's a mask in which every pixel is
selected a different amount

85
00:05:18,869 --> 00:05:22,309
matching the luminosity values the image
pixel for pixel

86
00:05:22,309 --> 00:05:27,860
ballard said like to just the dark
portions at this image

87
00:05:27,860 --> 00:05:32,300
I'd start by creating all the darks
masks

88
00:05:32,300 --> 00:05:39,249
in the channels panel and that click on
each one to see which one

89
00:05:39,249 --> 00:05:44,020
looks like it'll target the areas that I
want to adjust darks

90
00:05:44,020 --> 00:05:48,289
dark darks shattered arcs

91
00:05:48,289 --> 00:05:52,839
supra darks culture Dirks

92
00:05:52,839 --> 00:05:57,119
I think the dark darks

93
00:05:57,119 --> 00:06:00,819
targets the darkest areas pretty well
but I'll pick them more restrictive

94
00:06:00,819 --> 00:06:01,779
shattered arcs

95
00:06:01,779 --> 00:06:08,499
to make sure my adjustment doesn't bleed
into the later areas go back to the RGB

96
00:06:08,499 --> 00:06:09,439
color image

97
00:06:09,439 --> 00:06:12,479
the news the TK Actions panel

98
00:06:12,479 --> 00:06:20,689
to create my shadow darks curves
adjustment layer

99
00:06:20,689 --> 00:06:24,370
alt clicking on the mask shows is that
the lightest portions at the mask

100
00:06:24,370 --> 00:06:27,330
are concentrated in those dark
aspersions on the image that's where

101
00:06:27,330 --> 00:06:29,310
most server adjustment will take affect

102
00:06:29,310 --> 00:06:34,240
open up the curse dialogue

103
00:06:34,240 --> 00:06:39,590
and i cant lightner shadows through the
mask by dragging the curve up

104
00:06:39,590 --> 00:06:43,639
or darken them by dragging the curve
down

105
00:06:43,639 --> 00:06:47,620
how we can see that that adjustment is
being targeted towards the darkest

106
00:06:47,620 --> 00:06:48,800
portions of the image

107
00:06:48,800 --> 00:06:51,939
as we saw previously

108
00:06:51,939 --> 00:06:55,159
I can also use the contextual tool to

109
00:06:55,159 --> 00:06:58,400
make my kurds adjustment by dragging
directly on the image

110
00:06:58,400 --> 00:07:02,710
itself however when lightning in image

111
00:07:02,710 --> 00:07:06,439
I like to use the screen blending mode
to do the Lightning

112
00:07:06,439 --> 00:07:09,779
that leaves me my curve unaffected

113
00:07:09,779 --> 00:07:13,580
and now I can use the curve to further
affect the contrast

114
00:07:13,580 --> 00:07:21,710
a my lightning adjustment

115
00:07:21,710 --> 00:07:24,690
C&C that I've lightened the dark areas

116
00:07:24,690 --> 00:07:31,480
and maintain contrast with the curve I
can also shift click on the mask

117
00:07:31,480 --> 00:07:34,700
to turn the mask off and see what the
adjustment would look like without the

118
00:07:34,700 --> 00:07:35,260
