1
00:00:01,200 --> 00:00:05,066
In this lecture, we'll explore
light rooms, radial filter.
2
00:00:05,133 --> 00:00:09,900
Before we get started,
please load image NY 003.
3
00:00:09,900 --> 00:00:21,933
jpg in the develop module.
4
00:00:22,000 --> 00:00:26,100
By looking at this image,
we can see that most of it is grayscale,
5
00:00:26,166 --> 00:00:30,866
which adds a very cinematic effect
to the overall composition.
6
00:00:30,933 --> 00:00:33,833
Earlier,
when we worked with the gradient filter,
7
00:00:33,833 --> 00:00:36,600
you would have noticed
that the adjustments we applied were done
8
00:00:36,600 --> 00:00:42,100
so in a linear fashion, either
vertically or horizontally.
9
00:00:42,200 --> 00:00:44,600
The radial filter allows us to make basic
10
00:00:44,600 --> 00:00:48,700
adjustments in a circular method
rather than linear.
11
00:00:48,766 --> 00:00:51,466
For this example will be adding
dramatic shadows
12
00:00:51,466 --> 00:00:55,933
and highlights to this image
using the radial filter.
13
00:00:56,033 --> 00:00:58,133
To get started, activate the radio
14
00:00:58,133 --> 00:01:02,200
filter tool by clicking on it over here.
15
00:01:02,266 --> 00:01:05,266
As soon as you click on it,
you'll see the adjustments.
16
00:01:05,266 --> 00:01:08,666
The same way
we did with the graduated filter.
17
00:01:08,733 --> 00:01:10,400
And in this case, what we want to do
18
00:01:10,400 --> 00:01:15,700
is decrease the exposure of the road
in comparison to the rest of the shot.
19
00:01:15,766 --> 00:01:18,633
We need to start out
by drawing our radius.
20
00:01:18,633 --> 00:01:28,733
So hold your left mouse button down
and just draw a circle out
21
00:01:28,800 --> 00:01:30,400
and try to have the middle
22
00:01:30,400 --> 00:01:35,733
of the circle encompass
as much of the road as possible.
23
00:01:35,800 --> 00:01:38,600
Okay, so now in my Adjustments panel,
24
00:01:38,600 --> 00:01:42,166
the color temperature has changed,
25
00:01:42,266 --> 00:01:44,133
so I'm going to set that back to zero
26
00:01:44,133 --> 00:01:47,133
because I did not want to affect
the color temperature.
27
00:01:47,266 --> 00:01:51,433
What I did want to do
was decrease the exposure of the road
28
00:01:51,433 --> 00:02:02,133
in comparison to the rest of the shot.
29
00:02:02,200 --> 00:02:05,133
So as in making this adjustment,
you can see that the area that's
30
00:02:05,133 --> 00:02:10,966
being impacted is actually the area behind
the radius that I've drawn.
31
00:02:11,066 --> 00:02:13,766
What I need to do here is invert this
mask.
32
00:02:13,766 --> 00:02:17,400
So place
a checkmark in the invert mask checkbox.
33
00:02:17,466 --> 00:02:21,566
In that way the adjustments we make
are going to be impacted
34
00:02:21,566 --> 00:02:29,166
inside the radius of our circle.
35
00:02:29,233 --> 00:02:30,133
So you can see here
36
00:02:30,133 --> 00:02:35,466
I decreased the exposure value of the road
and that the exposure has been decreased
37
00:02:35,533 --> 00:02:40,700
intensely in the center of our radius
and then it gradually transitions out.
38
00:02:40,900 --> 00:02:44,933
If you want to reposition
the radius, you can just click on the pin
39
00:02:45,000 --> 00:02:48,966
and drag your mouse to the new location.
40
00:02:49,033 --> 00:02:54,066
If you want to change the size
or rotate it, you can as well
41
00:02:54,133 --> 00:02:57,133
just drag any of these handles here
42
00:02:57,366 --> 00:03:00,900
to expand
or contract it to rotated position
43
00:03:00,900 --> 00:03:05,033
your mouse just slightly
above the perimeter of the filter.
44
00:03:05,033 --> 00:03:07,300
And you can you can rotate it.
45
00:03:07,366 --> 00:03:08,733
Hold your left mouse button down.
46
00:03:08,733 --> 00:03:10,700
Just drag it
47
00:03:10,700 --> 00:03:14,966
to suit your needs.
48
00:03:15,066 --> 00:03:16,833
These are in addition to the exposure.
49
00:03:16,833 --> 00:03:25,966
I'm also going
to bring down the shadows a bit.
50
00:03:26,033 --> 00:03:26,966
So that's the difference
51
00:03:26,966 --> 00:03:30,266
between lightning them and darkening them.
52
00:03:30,333 --> 00:03:34,433
So now I'm only targeting the darker
range of colors within my filter.
53
00:03:34,566 --> 00:03:41,200
So this is the before and after.
54
00:03:41,266 --> 00:03:43,533
So as you can see,
it's a bit more dramatic.
55
00:03:43,533 --> 00:03:48,600
Now let's go ahead and add another radial
filter to a different part of this image.
56
00:03:48,666 --> 00:03:59,233
So let's see, for example,
we wanted to target the rocks
57
00:03:59,300 --> 00:04:01,500
and we to decrease the exposure.
58
00:04:01,500 --> 00:04:05,200
I'm going to invert the mask
59
00:04:05,300 --> 00:04:06,900
and once again, my color temperature,
60
00:04:06,900 --> 00:04:09,266
I'm just going
to bring that back down to zero.
61
00:04:09,266 --> 00:04:16,233
I only want to effect the exposure
62
00:04:16,300 --> 00:04:17,933
similar to the graduated filter.
63
00:04:17,933 --> 00:04:22,066
If you hover your mouse down over the pin,
you see a red mask that indicates
64
00:04:22,066 --> 00:04:26,100
exactly where our exposure setting starts
65
00:04:26,100 --> 00:04:30,900
and where transitions out.
66
00:04:30,966 --> 00:04:31,800
You can switch
67
00:04:31,800 --> 00:04:36,033
from each filter
by clicking on its corresponding pin.
68
00:04:36,100 --> 00:04:38,566
If you don't want to see the pins,
69
00:04:38,566 --> 00:04:43,500
then you can edit
the show Edit Pins option
70
00:04:43,566 --> 00:04:47,000
just like we did
with the other tools that we worked with.
71
00:04:47,100 --> 00:04:51,266
Okay, so to see the completed effect,
this is before
72
00:04:51,333 --> 00:04:57,266
and this is after.
73
00:04:57,333 --> 00:04:58,833
If you want to apply the effect,
74
00:04:58,833 --> 00:05:02,100
click the done button
75
00:05:02,166 --> 00:05:04,000
and it'll render the effect on the image.
76
00:05:04,000 --> 00:05:08,033
And so we hope you enjoyed that tutorial
and we'll see you in the next lecture.
