100:00:00,000 --> 00:00:06,560how d

1
00:00:00,000 --> 00:00:06,560
how do we know when callers are real
this graphic is in sRGB which is what

2
00:00:06,560 --> 00:00:13,670
I'm using for this session where the
cursor is it reads to 5500 this is a

3
00:00:13,670 --> 00:00:19,150
real color it's the greatest breadth at
this RGB can possibly producing it's

4
00:00:19,150 --> 00:00:23,080
pretty close to being ready spread the
disease monitor can reproduce on the

5
00:00:23,080 --> 00:00:26,660
right side of the Info palette you'll
notice that there's some CMYK

6
00:00:26,660 --> 00:00:32,419
equivalents $0.99 100 0 I should
actually say those little bit more

7
00:00:32,419 --> 00:00:35,399
strongly because you see the H one of
those has an exclamation point after

8
00:00:35,399 --> 00:00:45,710
your 10 make what those explanation
points mean is that the caller is not

9
00:00:45,710 --> 00:00:53,100
credible in CMYK it's telling us that's
what we're gonna get really match what

10
00:00:53,100 --> 00:00:57,500
we've got on the screen because that
color is out of gamete let's just see

11
00:00:57,500 --> 00:01:04,519
what happens if we put it in CMYK color
no longer matches what we had originally

12
00:01:04,519 --> 00:01:10,400
because that's impossible and further we
have sort of a strange artifact shown up

13
00:01:10,400 --> 00:01:13,750
in the middle of the screen where the
center seems to be getting a little bit

14
00:01:13,750 --> 00:01:22,930
darker ok back to RGB now what's changed
the right side of the info power to read

15
00:01:22,930 --> 00:01:27,270
la be equivalents were having in CMYK
equals I recommend you have your info

16
00:01:27,270 --> 00:01:29,729
palate this way most of the time

17
00:01:29,729 --> 00:01:36,650
ok so now this same color measures 54 L
81 a and seventy be that's not even

18
00:01:36,650 --> 00:01:40,759
close to being as red as leb can produce
because the reddest read that it could

19
00:01:40,759 --> 00:01:46,630
do is one hundred and twenty-seven in
the a channel and 127 in the beach so

20
00:01:46,630 --> 00:01:53,460
that's almost twice as red as this and
yet it can't be reproduced in LGB

21
00:01:53,460 --> 00:01:59,759
because this is the reddest read that
can make better red than this actually

22
00:01:59,759 --> 00:02:03,740
exist in real life will certainly they
do when we are painted with them all the

23
00:02:03,740 --> 00:02:06,190
time and laser beams are certainly

24
00:02:06,190 --> 00:02:12,660
than the screen can display we can
theoretically she's such Reds in LA be

25
00:02:12,660 --> 00:02:18,560
by simply jacking up the a in the beach
and we can get them both up 227 it's a

26
00:02:18,560 --> 00:02:23,690
limited practical matter because we
can't print them what we have here is as

27
00:02:23,690 --> 00:02:29,170
red as we can go even on the best inkjet
printer currently available but what

28
00:02:29,170 --> 00:02:37,540
happens if we try if we're going to leb
and call up he unveiled Layers palette

29
00:02:37,540 --> 00:02:46,730
adjustment curves later on there and get
with our normal sort steepening abie

30
00:02:46,730 --> 00:02:59,240
curves and what we get here be radically
a red red actually not really in the

31
00:02:59,240 --> 00:03:02,780
center where the cursor is the color
scarcely changed at all

32
00:03:02,780 --> 00:03:06,480
it can't get any better at least the
monitor can't display it but if you look

33
00:03:06,480 --> 00:03:14,780
at the Info palette it's theoretically
becoming a rather read in reality the

34
00:03:14,780 --> 00:03:20,060
only thing that's changing apparently is
the stuff out here which becomes a red

35
00:03:20,060 --> 00:03:24,730
that we can reproduce on the monitor and
so that's changing what the apparently

36
00:03:24,730 --> 00:03:28,600
we're losing detail as a result it's
interesting to see what happens if we

37
00:03:28,600 --> 00:03:36,060
now changed the the right side of the
Info palette to RGB so this is after

38
00:03:36,060 --> 00:03:42,550
this is before and you see the RGB
numbers don't change they can to 5500 is

39
00:03:42,550 --> 00:03:50,820
the brightest red we can make it reality
does read that were asking for here in

40
00:03:50,820 --> 00:03:52,880
leb actually exist

41
00:03:52,880 --> 00:03:56,269
well that depends on whether you're more
interested in what we're theoretically

42
00:03:56,269 --> 00:04:01,910
asking for or what we will in real life
get if we try to use this file because

43
00:04:01,910 --> 00:04:07,190
what we're asking for in principle is
something like this but little bit rarer

44
00:04:07,190 --> 00:04:11,519
we lose a lot of detail in real life
because this is what we're going to be

45
00:04:11,519 --> 00:04:17,660
getting if we go into RGB this makes it
a very dangerous situation for us

46
00:04:17,660 --> 00:04:22,800
originally we had an RGB file that was
outside of the CMYK gamut if we were

47
00:04:22,800 --> 00:04:27,040
thinking about taking that into CMYK we
had a nice big morning in this in the

48
00:04:27,040 --> 00:04:31,420
info power telling us that was out of
the CMYK game furthermore when we

49
00:04:31,420 --> 00:04:37,270
converted easily see what the damage was
now the situation is we haven't led file

50
00:04:37,270 --> 00:04:42,270
that's outside of the RGB gammon leon no
warning in the Info palette and if we

51
00:04:42,270 --> 00:04:47,050
convert RGB it'll pretty much look the
same way that it does right now on the

52
00:04:47,050 --> 00:04:54,330
screen now what happens we try to
restore with a curve in the channel some

53
00:04:54,330 --> 00:05:06,590
of the details that's apparently being
lost in the background maybe like that

54
00:05:06,590 --> 00:05:12,470
well that's pretty strange that's that's
a very dark I'll tell you but yet it's

55
00:05:12,470 --> 00:05:19,770
not showing up as a black so there's
there's any help that's as black as can

56
00:05:19,770 --> 00:05:21,460
possibly be

57
00:05:21,460 --> 00:05:27,500
I guess this might be reasonable way to
convert the file be a lot better than it

58
00:05:27,500 --> 00:05:32,490
was originally while the original look
like that well maybe this would work

59
00:05:32,490 --> 00:05:36,980
maybe not who knows but now we can
actually start to talk about what's real

60
00:05:36,980 --> 00:05:42,900
and what's artificial is this caller
real I don't know possibly I don't think

61
00:05:42,900 --> 00:05:46,970
so it's probably probably the color of
its being asked for is better than laser

62
00:05:46,970 --> 00:05:52,530
beam so it doesn't really matter we
can't print it out here this is

63
00:05:52,530 --> 00:05:56,810
definitely not real color this is
absolutely an imaginary color because

64
00:05:56,810 --> 00:06:03,670
what's being called for is a value of 0
that's as dark as it can possibly be and

65
00:06:03,670 --> 00:06:09,980
an a value of ADB of 64 so that's
brilliantly read so we're asking for a

66
00:06:09,980 --> 00:06:14,950
brilliantly red pure black and I put it
to you there ain't no such animal but

67
00:06:14,950 --> 00:06:19,690
yet when we asked for Photoshop has to
do something let me try to make this

68
00:06:19,690 --> 00:06:24,690
little clear I'm gonna ditch discouraged
them and I just meant later go over here

69
00:06:24,690 --> 00:06:30,790
to the color picker set a new background
color of let's say

70
00:06:30,790 --> 00:06:38,070
100 extremely dark over here and delete
this the black come back and set a

71
00:06:38,070 --> 00:06:46,220
foreground color to this same one but
one of the old channel below 100 in each

72
00:06:46,220 --> 00:06:52,710
of the A&B so this is the imaginary
color almost pure black but

73
00:06:52,710 --> 00:06:58,360
simultaneously the most brilliantly
imaginable read the whole hit the X key

74
00:06:58,360 --> 00:07:03,960
so that we can make that the background
color make a smaller selection in here

75
00:07:03,960 --> 00:07:13,230
and delete that so that now we have on
the outside box the real color pure

76
00:07:13,230 --> 00:07:18,580
black on the inside the imaginary color
the color that brilliantly read but also

77
00:07:18,580 --> 00:07:24,800
pure black what happens if we convert to
grayscale

78
00:07:24,800 --> 00:07:30,350
maybe we get this doesn't look like it
matches that but yet it must because the

79
00:07:30,350 --> 00:07:35,430
leb files calling for the same darkness
throughout its being displayed is

80
00:07:35,430 --> 00:07:41,920
something very different of course what
happens if we go to RGB well this

81
00:07:41,920 --> 00:07:47,220
imaginary color theoretically exists in
leb but it certainly doesn't exist in

82
00:07:47,220 --> 00:07:55,340
RGB so photoshop has to ask itself what
is this fool looking for here when he's

83
00:07:55,340 --> 00:07:59,560
asking for a pure black that's also
bring lee read and Photoshop scratches

84
00:07:59,560 --> 00:08:07,070
his head and essentially splits the
difference we got RGB and now it doesn't

85
00:08:07,070 --> 00:08:11,580
appear that there's been a change of
course there's been enormous one switch

86
00:08:11,580 --> 00:08:20,350
back to leb in this part of the Info
palette that's in leb that's an RGB

87
00:08:20,350 --> 00:08:25,190
notice how the leb values changed
enormously on the right side of the Info

88
00:08:25,190 --> 00:08:34,700
palette from 1 100 102 1941 26 and yet
the appearance on the screen changed

89
00:08:34,700 --> 00:08:38,979
almost not at all and if we convert this
one to grayscale you know that it's an

90
00:08:38,979 --> 00:08:41,360
RGB

91
00:08:41,360 --> 00:08:46,649
would certainly not pure black or
anything like it because the imaginary

92
00:08:46,649 --> 00:08:51,630
color got converted into real color and
at this point we can stop discussing

93
00:08:51,630 --> 00:08:56,310
this theory and start going into

59
00:05:32490——> 00:05:36980

什么人工这是来电

61
00:05:42900——> 00:05:46970
所以很可能被问
颜色比激光

62
00:05:46970——> 00：05:52530
梁真的无关紧要我们
不能打印出来，这是

63
00:05:52530——> 00:05:56810
绝对不是真实的颜色这是
绝对想象中的色彩是因为

00:05:56810——> 00:06:03670
什么被称为是一个价值0
是这样的可能和

65
00:06:03670——> 00:06:09980
一值64，亚行的黑暗
出色的读所以我们要求一个

00:06:09980——> 00:06:14950
出色红纯黑色，我把它
你没有动物但

67
00:06:14950——> 00:06:19690
但当我们问PS图象处理软件有
做一些让我努力让这

68
00:06:19690——> 00:06:24690
点清楚我要沟气馁
他们，我只是说以后就在这里

69
00:06:24，690——> 00:06:30790
的颜色选择器设置新的背景
颜色让我们说

70
00:06:30790——> 00:06:38070
100极其黑暗在这里删除
这黑回来，设定一个

00:06:38070——> 00:06:46220
前景颜色相同但
之一老渠道100以下各

72
00:06:46220——> 00:06:52710

色彩几乎纯黑色但

73
00:06:52710——> 00:06:58360
同时最出色的
想象阅读整个打X键

74
00:06:58360——> 00:07:03960
从而使背景
色彩使较小的选择在这里

75
00:07:03960——> 00:07:13230

00:07:13230——> 00:07:18580
黑色在假想色
颜色，出色的阅读也

77
00:07:18580——> 00:07:24800
纯黑色会发生什么，如果我们转换到
灰度

78
00:07:24800——> 00:07:30350
也许我们得到这个看上去并不
匹配，但它必须因为

79
00:07:30350——> 00:07:35430
LEB文件要求相同的黑暗
在被显示的是

80

非常不同的东西当然
发生如果我们去RGB这

81
00:07:41920——> 00:07:47220
假想色理论存在
LEB但肯定不存在

82
00:07:47220——> 00:07:55340
RGB所以PS图象处理软件已经问自己这个傻瓜是
在这里找他

83
00:07:55340——> 00:07:59560
求纯黑色，也
把李女士读PS图象处理软件划痕

84
00:07:59560——> 00:08:07070
摇头，基本上把
差得到RGB和现在不

85
00:08:07070——> 00:08:11580
