1
00:00:03,750 --> 00:00:07,450
the
2
00:00:07,450 --> 00:00:12,169
okay for solo guitar intro before we go
into images
3
00:00:12,169 --> 00:00:17,710
so what is bid beat dat specifies how
much caller possibilities we can have
4
00:00:17,710 --> 00:00:19,330
for each pixel in the image
5
00:00:19,330 --> 00:00:23,290
are many possibilities we can happen how
many we actually have
6
00:00:23,290 --> 00:00:28,810
duds or not decided by the image itself
but how many possibilities weekend
7
00:00:28,810 --> 00:00:35,120
K so if you would like to learn more
about beaded in general in all of these
8
00:00:35,120 --> 00:00:38,329
you can check out this video here and
you can click on
9
00:00:38,329 --> 00:00:42,469
if you have annotations open inside you
to begin click on it if not I'll evil
10
00:00:42,469 --> 00:00:47,069
link I did in my blog or hear a big load
a YouTube video seeking to get out
11
00:00:47,069 --> 00:00:50,269
the video you cannot you can also search
on my channel it's called
12
00:00:50,269 --> 00:00:54,609
be Dept in dept all you never wanted to
know about bit
13
00:00:54,609 --> 00:00:59,069
it's just a very extensive way of
looking at it from start to finish so I
14
00:00:59,069 --> 00:01:01,659
opted out you should be able to follow
anything regarding
15
00:01:01,659 --> 00:01:06,080
did but in case you already know that
let's continue
16
00:01:06,080 --> 00:01:10,930
so standard RGB image in eight bits per
channel mode can have up to about
17
00:01:10,930 --> 00:01:14,620
sixteen point seven million the stink
awesome color possibilities
18
00:01:14,620 --> 00:01:18,570
again can hang out doesn't mean you
always had but
19
00:01:18,570 --> 00:01:21,630
60.7 million okay
20
00:01:21,630 --> 00:01:25,140
now optimists a doubt .biz human I
21
00:01:25,140 --> 00:01:29,810
would be able to distinguish about 10
million just in color possibilities
22
00:01:29,810 --> 00:01:33,110
which is more than enough then for that
23
00:01:33,110 --> 00:01:36,980
eight bits per channel no image to give
us a smooth gradations
24
00:01:36,980 --> 00:01:40,210
rights AB's per channel image for collar
three channel
25
00:01:40,210 --> 00:01:44,310
has more now bits to present a smooth
grade
26
00:01:44,310 --> 00:01:44,700
the pen
27
00:01:44,700 --> 00:01:49,290
on the viewing device not all monitors
can do it but it should be enough
28
00:01:49,290 --> 00:01:53,870
to the question is if a bitch per
channel mode is enough to display a
29
00:01:53,870 --> 00:01:55,520
smooth continuous tone
30
00:01:55,520 --> 00:01:59,300
why would we ever need more and how much
more we need
31
00:01:59,300 --> 00:02:02,500
right offers lets talk about why would
we need more
32
00:02:02,500 --> 00:02:07,390
okay so there's this thing called poster
is Asian or banned me everybody talks
33
00:02:07,390 --> 00:02:09,369
about you must have heard about it
basically
34
00:02:09,369 --> 00:02:12,530
what happens is that when we don't
happen now
35
00:02:12,530 --> 00:02:17,430
beats inside an image we can display
smooth gradient
36
00:02:17,430 --> 00:02:21,720
or smooth gradations inside phase sore
some other parts with the image
37
00:02:21,720 --> 00:02:26,690
now when we do have it and we do some
extensive editing title Photoshop
38
00:02:26,690 --> 00:02:30,860
its destructive so we lose some that and
we need more
39
00:02:30,860 --> 00:02:34,300
how much more we need and when we needed
40
00:02:34,300 --> 00:02:37,380
dogs the key point I want right answer
in this video
41
00:02:37,380 --> 00:02:41,739
so the next best thing out
42
00:02:41,739 --> 00:02:45,770
a bit would be sixteen-bit or purists
out there that's actually peaked in bits
43
00:02:45,770 --> 00:02:46,830
per channel I have
44
00:02:46,830 --> 00:02:50,049
bt i mentioned earlier about that so you
can check that out a cute one
45
00:02:50,049 --> 00:02:53,820
so the question is when would you choose
a bit when we choose
46
00:02:53,820 --> 00:02:57,320
16 bits per channel mode now in a row
workflow
47
00:02:57,320 --> 00:03:01,650
as you can see in this graphic here
we're always working with more than
48
00:03:01,650 --> 00:03:02,290
upbeat
49
00:03:02,290 --> 00:03:05,980
inside a camera captured and of course
insider rock birder
50
00:03:05,980 --> 00:03:09,850
only place where this is somewhat of a
debate
51
00:03:09,850 --> 00:03:13,280
is when we doing Photoshop entity and
thats
52
00:03:13,280 --> 00:03:16,420
exactly depart where all this confusion
comes in
53
00:03:16,420 --> 00:03:20,660
and that's what I want talk about in
this lead there's also a matter of
54
00:03:20,660 --> 00:03:23,560
outputting to clients and so on and so
forth imprinting
55
00:03:23,560 --> 00:03:26,920
that's almost always a date and I will
talk about it some other media
56
00:03:26,920 --> 00:03:30,209
for now all i wanna talk about and
discuss is
57
00:03:30,209 --> 00:03:34,290
actually when do we choose 8 and when
sixteen-day
58
00:03:34,290 --> 00:03:37,940
alright so that now that we understand
I'd
59
00:03:37,940 --> 00:03:41,100
we need more we have more than enough
60
00:03:41,100 --> 00:03:45,209
in 8-bit per channel mode we have more
than enough bids
61
00:03:45,209 --> 00:03:48,650
to present or shows more radians
62
00:03:48,650 --> 00:03:52,650
week don't have enough sometimes that
when we do our edits
63
00:03:52,650 --> 00:03:56,379
inside a Photoshop that's a key word
here inside a Photoshop
64
00:03:56,379 --> 00:04:01,920
that we can retain are smooth gradations
after we made some changes like curves
65
00:04:01,920 --> 00:04:05,330
the levels and things like that well
this is an interesting image
66
00:04:05,330 --> 00:04:08,349
me show you call the original image look
67
00:04:08,349 --> 00:04:12,769
okay so this image had relations in the
background not
68
00:04:12,769 --> 00:04:15,810
too hard but there is some it has
69
00:04:15,810 --> 00:04:19,209
pretty harsh shadows here and highlights
it's also
70
00:04:19,209 --> 00:04:24,979
quite heavenly overexposed I would say
we barely have some detail left ear
71
00:04:24,979 --> 00:04:29,410
but because this is a RAW file you
working inside a row converter
72
00:04:29,410 --> 00:04:33,870
we can take full advantage or all the
raw data that came from camera
73
00:04:33,870 --> 00:04:39,550
as well as the fact that we are working
in 16-bit camera works in fact in 16-bit
74
00:04:39,550 --> 00:04:43,430
or channel sadat's more than enough
75
00:04:43,430 --> 00:04:47,490
I can do all kinds of crazy kids and
nothing bad happened to do seems pretty
76
00:04:47,490 --> 00:04:47,949
much
77
00:04:47,949 --> 00:04:51,570
docked if i activate my adjustments so
you can see
78
00:04:51,570 --> 00:04:54,889
I have managed to pull out some details
in the face
79
00:04:54,889 --> 00:04:59,150
and you know I have even smooth out the
gradients a little bit here
80
00:04:59,150 --> 00:05:02,820
so it was in doubt that now here's the
key question
81
00:05:02,820 --> 00:05:06,729
what I'm going to do next with this
image that's important to know
82
00:05:06,729 --> 00:05:10,910
because doug wilder side how will I
proceed with this image 18
83
00:05:10,910 --> 00:05:15,900
take it into Photoshop in here at the
bottom there isn't option called
84
00:05:15,900 --> 00:05:20,150
basically a link to choose your workflow
85
00:05:20,150 --> 00:05:24,810
options and now among other things we
are not interested at the moment there
86
00:05:24,810 --> 00:05:26,229
is an option called Dept
87
00:05:26,229 --> 00:05:29,830
the course if I am done with all my
edits
88
00:05:29,830 --> 00:05:33,610
and this is the economy that I want I
may just have to want to clone and
89
00:05:33,610 --> 00:05:37,099
keel a bunch of stuff den I would choose
eight beats
90
00:05:37,099 --> 00:05:40,820
per channel here however if I know
91
00:05:40,820 --> 00:05:45,039
dot client might change their mind might
want some kind of a collar correction
92
00:05:45,039 --> 00:05:45,599
today's
93
00:05:45,599 --> 00:05:48,780
or I decided maybe I wanna try some
stuff
94
00:05:48,780 --> 00:05:51,669
week to adjustment layers inside
Photoshop
95
00:05:51,669 --> 00:05:55,100
then I want some extra extra bits for
editing
96
00:05:55,100 --> 00:06:01,050
duckies I would choose 16 now for
demonstration purposes let sadie is
97
00:06:01,050 --> 00:06:05,760
aidid have already crosses song is not
to click Cancel
98
00:06:05,760 --> 00:06:08,830
and here's the same violence out a
Photoshop
99
00:06:08,830 --> 00:06:11,960
now and say I do my
100
00:06:11,960 --> 00:06:16,310
it it's here look at it face you're
right I did
101
00:06:16,310 --> 00:06:20,300
made small adjustments I'm a complete
cure for healing in cloning nothing
102
00:06:20,300 --> 00:06:20,880
major
103
00:06:20,880 --> 00:06:23,960
and now I have decided what word
104
00:06:23,960 --> 00:06:27,889
Klein has decided well wait a minute we
want you to change this image we want
105
00:06:27,889 --> 00:06:28,620
you to
106
00:06:28,620 --> 00:06:33,919
out some color correction to this may be
more by Bryn maybe more dynamic maybe I
107
00:06:33,919 --> 00:06:34,979
can apply here
108
00:06:34,979 --> 00:06:38,070
a selective color adjustment is
109
00:06:38,070 --> 00:06:42,120
making more fashionable if you will at
this point
