1
00:00:03,440 --> 00:00:07,210
to create the most accurate and balanced
luminosity masks it's important that you
2
00:00:07,210 --> 00:00:09,780
have established the correct color
settings within Lightroom
3
00:00:09,780 --> 00:00:14,330
Adobe Camera Raw and Photoshop arriving
at the color settings we now know to be
4
00:00:14,330 --> 00:00:15,710
correct was a bit of a journey
5
00:00:15,710 --> 00:00:18,499
is probably more than you wanna know but
let me give you a little back story
6
00:00:18,499 --> 00:00:19,249
anyway
7
00:00:19,249 --> 00:00:22,480
60k actions were first released in 2006
8
00:00:22,480 --> 00:00:25,630
they were built around the default color
settings in Photoshop
9
00:00:25,630 --> 00:00:28,939
which are Adobe RGB 1998 for the color
space
10
00:00:28,939 --> 00:00:33,980
and dot gain 20 percent for the gray
space however it turns out the dot gain
11
00:00:33,980 --> 00:00:37,260
20 percent gray space is optimized for
offset printing
12
00:00:37,260 --> 00:00:43,000
which uses a CMYK color space so it is a
perfectly match with the Adobe RGB 98
13
00:00:43,000 --> 00:00:47,350
all across the mass could still be
generated with these default settings
14
00:00:47,350 --> 00:00:51,340
they were perfectly symmetrical which
required some additional steps to get
15
00:00:51,340 --> 00:00:53,440
luminosity masks that were balanced
16
00:00:53,440 --> 00:00:57,970
shooting was just a quirk Photoshop Tony
sticky actions and tutorials remain
17
00:00:57,970 --> 00:01:01,000
unchanged until late in the fall of 2012
18
00:01:01,000 --> 00:01:04,939
parted the way into production of these
videos tony mentioned to me that he had
19
00:01:04,939 --> 00:01:07,310
been experimenting with different race
pace settings
20
00:01:07,310 --> 00:01:12,090
and notice that the gray gamma 2.2 gray
space produce perfectly symmetrical
21
00:01:12,090 --> 00:01:16,189
and more finely detailed luminosity
masks I contacted my friend
22
00:01:16,189 --> 00:01:20,490
and longtime Photoshop guru Mac Colbert
why the people behind pixel genius
23
00:01:20,490 --> 00:01:24,340
Mac was able to tell us that even though
dot gain 20 percent is the default
24
00:01:24,340 --> 00:01:25,700
setting in Photoshop
25
00:01:25,700 --> 00:01:30,499
that gray gamma 2.2 was specifically
designed to match the grease kilt our
26
00:01:30,499 --> 00:01:31,009
values
27
00:01:31,009 --> 00:01:34,920
to corresponding color to analyze in the
Adobe 98 color space
28
00:01:34,920 --> 00:01:39,729
furthermore when the expanded Pro Photo
Color space was introduced in Photoshop
29
00:01:39,729 --> 00:01:43,259
it was paired work with the gray gamma
1.8 gray space
30
00:01:43,259 --> 00:01:46,740
using one of these two correct pairings
have color space
31
00:01:46,740 --> 00:01:51,090
increase pace enables Photoshop to
create the most balanced and symmetrical
32
00:01:51,090 --> 00:01:54,630
luminosity masks with the smoothest
luminosity transitions
33
00:01:54,630 --> 00:01:58,200
so before you go any further with
luminosity masking
34
00:01:58,200 --> 00:02:01,729
I recommend that you establish one have
the correct color space grey space
35
00:02:01,729 --> 00:02:03,200
pairings in Photoshop
36
00:02:03,200 --> 00:02:07,069
additionally if you're working with an
older version of the TK actions
37
00:02:07,069 --> 00:02:11,090
should update to the current version
you'll need to decide which color space
38
00:02:11,090 --> 00:02:13,400
will be your working color space in
Photoshop
39
00:02:13,400 --> 00:02:15,300
Adobe RGB 1998
40
00:02:15,300 --> 00:02:19,660
98 was the standard for many years and
is still a perfectly viable option
41
00:02:19,660 --> 00:02:24,150
however many photographers including
myself are now working in the Pro Photo
42
00:02:24,150 --> 00:02:26,670
Color space for its expanded color range
43
00:02:26,670 --> 00:02:30,360
there are potential advantages both now
and in the future
44
00:02:30,360 --> 00:02:34,270
to working in the Pro Photo Color space
but if you do it's also important to
45
00:02:34,270 --> 00:02:37,360
make sure you use the 16 bit mode to
maintain
46
00:02:37,360 --> 00:02:41,880
smooth color transitions once you've
decided which color space will be your
47
00:02:41,880 --> 00:02:43,160
working color space
48
00:02:43,160 --> 00:02:47,180
your first want to set up late room
and/or Adobe Camera Raw
49
00:02:47,180 --> 00:02:51,390
to open image is in the right space
let's start with Lightroom
50
00:02:51,390 --> 00:02:54,610
set the color space in Lightroom
51
00:02:54,610 --> 00:02:58,040
go to the Edit menu and select
Preferences
52
00:02:58,040 --> 00:03:01,220
in the Preferences dialog
53
00:03:01,220 --> 00:03:04,870
you can set the file format type the
color space and the bit depth
54
00:03:04,870 --> 00:03:09,460
here's where you can choose your color
space to be either pro for RGB
55
00:03:09,460 --> 00:03:17,390
for Adobe RGB 1998 if you use Adobe
Camera Raw as your off I'll
56
00:03:17,390 --> 00:03:24,100
editor the settings are a little
different click the blue link at the
57
00:03:24,100 --> 00:03:25,310
bottom of the screen
58
00:03:25,310 --> 00:03:29,230
and thus open a dialogue that allows you
to set the color space
59
00:03:29,230 --> 00:03:34,239
and bit depth here you can also choose
Adobe RGB 1998
60
00:03:34,239 --> 00:03:43,280
or Pro Photo RGB
61
00:03:43,280 --> 00:03:46,510
now let's set the correct color space
and grace base pairing
62
00:03:46,510 --> 00:03:50,230
within Photoshop go to the Edit menu
63
00:03:50,230 --> 00:03:55,670
and select color settings and this
dialogue
64
00:03:55,670 --> 00:04:00,209
you can't say you're working space the
RGB color space
65
00:04:00,209 --> 00:04:05,120
again either Adobe RGB 1998 or Pro Photo
RGB
66
00:04:05,120 --> 00:04:09,690
and if you say Adobe 98 as you're
working space
67
00:04:09,690 --> 00:04:13,680
then you would wanna select gray gamma
2.2
68
00:04:13,680 --> 00:04:17,310
measure gray space if you select
69
00:04:17,310 --> 00:04:20,669
Pro Photo RGB is your work in color
space
70
00:04:20,669 --> 00:04:23,950
then you wanna set grey gamma one point
8
71
00:04:23,950 --> 00:04:27,460
has your gray space click OK
72
00:04:27,460 --> 00:04:33,650
and you're ready to go now that you have
the correct color space sparing setup
73
00:04:33,650 --> 00:04:37,870
your mask will be symmetrical and create
the most detailed luminosity selections
74
00:04:37,870 --> 00:04:40,880
to also ensure that the TK luminosity
mask
75
00:04:40,880 --> 00:04:42,760
actions will work properly in your
system
