00:00:10,700 --> 00:00:11,700
in this lesson
2
00:00:11,700 --> 00:00:14,066
we will learn how to merge converted deep images
3
00:00:14,066 --> 00:00:15,699
with native deep images
4
00:00:17,600 --> 00:00:19,366
alright we're in our shot set up
5
00:00:19,366 --> 00:00:20,833
and I've made a holdout
6
00:00:22,766 --> 00:00:24,366
for our fog going here
7
00:00:24,366 --> 00:00:25,599
we've got fog
8
00:00:27,600 --> 00:00:31,466
and it's just our noise going to a deep extrude
9
00:00:34,000 --> 00:00:35,466
connect it to everything else
10
00:00:36,500 --> 00:00:37,466
hold it out
11
00:00:38,466 --> 00:00:40,766
remove deep of course now in this case
12
00:00:42,400 --> 00:00:43,966
there's no Z depth being generated
13
00:00:43,966 --> 00:00:45,799
so there's no reason to have the whole Z depth
14
00:00:45,800 --> 00:00:47,266
whole Z depth pipe
15
00:00:48,900 --> 00:00:49,866
render this out
16
00:00:49,866 --> 00:00:51,666
I'll show you what this looks like
17
00:00:51,666 --> 00:00:52,966
looks pretty cool actually
18
00:00:52,966 --> 00:00:54,366
so we can see here
19
00:00:55,266 --> 00:00:56,433
this is what
20
00:00:57,666 --> 00:01:00,566
it looks like at the depth that we set
21
00:01:01,133 --> 00:01:01,766
so we can see
22
00:01:01,766 --> 00:01:06,233
obviously 100% opacity in the far background
23
00:01:06,333 --> 00:01:10,199
and then we get all the way to 100% transparency
24
00:01:10,200 --> 00:01:13,400
zero opacity in the foreground objects
25
00:01:17,500 --> 00:01:19,166
and in this particular case
26
00:01:19,800 --> 00:01:21,666
I didn't need to hold out the atmosphere
27
00:01:21,666 --> 00:01:22,633
from everything else
28
00:01:23,900 --> 00:01:26,566
and the reason was that because it's white
29
00:01:26,666 --> 00:01:28,566
all we really need to do is plus it
30
00:01:28,566 --> 00:01:32,366
so if you use a merge and there's no alpha channel
31
00:01:33,366 --> 00:01:34,666
that's just a plus
32
00:01:34,966 --> 00:01:36,266
and this particular case
33
00:01:36,266 --> 00:01:38,266
if we're merging something over something else
34
00:01:38,266 --> 00:01:39,466
without a holdout
35
00:01:40,133 --> 00:01:42,266
the result is just going to be a plus as well
36
00:01:47,300 --> 00:01:49,066
so for a particular example
37
00:01:49,066 --> 00:01:50,033
in this shot
38
00:01:50,400 --> 00:01:52,700
we don't need to go through the extra labour
39
00:01:54,166 --> 00:01:55,666
of hooking up all the holdouts
40
00:01:55,666 --> 00:01:56,733
to all the other elements
41
00:01:56,733 --> 00:01:58,366
and then rendering new holdouts
42
00:01:58,400 --> 00:01:59,566
it's unnecessary
43
00:02:00,566 --> 00:02:01,933
but in many other cases
44
00:02:01,933 --> 00:02:04,399
with different colors or different things
45
00:02:05,333 --> 00:02:08,466
I would definitely recommend doing that just to be safe
46
00:02:08,466 --> 00:02:10,933
you wouldn't want to make any mistakes
47
00:02:10,933 --> 00:02:14,033
and then accidentally change the look of your shot
48
00:02:15,533 --> 00:02:16,199
so there you go
49
00:02:16,200 --> 00:02:17,933
this is how you take any image
50
00:02:17,933 --> 00:02:20,633
and convert it to a deep image to use in a deep shot
51
00:02:21,266 --> 00:02:22,799
I think for atmospherics
52
00:02:22,900 --> 00:02:24,533
and other volumetric type images
53
00:02:24,533 --> 00:02:25,966
it's a really great technique
54
00:02:25,966 --> 00:02:28,699
that's super useful and will save you a ton of time
55
00:02:29,166 --> 00:02:30,299
uh it's also really cool
56
00:02:30,300 --> 00:02:33,166
because you can move through 3D space
57
00:02:34,366 --> 00:02:37,033
and that's something that is really amazing if
58
00:02:37,133 --> 00:02:38,566
if Grolo was moving
59
00:02:38,566 --> 00:02:40,399
forwards and backwards through space here
60
00:02:40,400 --> 00:02:45,400
it would actually give him more or less density
61
00:02:46,000 --> 00:02:48,400
I could give you a little quick demo of that
62
00:02:49,366 --> 00:02:50,899
just because it is so cool
63
00:02:53,766 --> 00:02:55,633
let me make a deep transform
64
00:02:59,733 --> 00:03:01,633
let's push Grolo back
65
00:03:04,000 --> 00:03:07,300
maybe a negative um 100
66
00:03:09,133 --> 00:03:11,199
- 1,000
67
00:03:13,100 --> 00:03:15,500
- 5,000
68
00:03:23,733 --> 00:03:25,466
to go a lot further than that
69
00:03:33,300 --> 00:03:35,433
we have now reached the end of the lesson
70
00:03:35,533 --> 00:03:37,866
and we've Learned how to merge converted deep images
71
00:03:37,866 --> 00:03:39,399
with native deep images
72
00:03:39,700 --> 00:03:41,033
in the next lesson
73
00:03:41,066 --> 00:03:43,499
we will learn how to create realistic depth of field
74
00:03:43,500 --> 00:03:44,766
using deep images
