00:00:01,970 --> 00:00:05,732
As much as I might like a vignette effect for certain images, I actually add it as
2
00:00:05,732 --> 00:00:09,437
a creative effect sometimes, as a matter-of-fact, generally speaking, with
3
00:00:09,437 --> 00:00:13,028
older images that show a vignetting, a darkening of the corners, I prefer to
4
00:00:13,028 --> 00:00:18,374
remove that effect. You can see in this image, the vignetting
5
00:00:18,374 --> 00:00:22,500
is rather obvious, especially up in the sky, where the sky is relatively bright.
6
00:00:22,500 --> 00:00:25,100
But in the corners, it appears quite dark.
7
00:00:25,100 --> 00:00:27,920
It's not quite as evident down below, because there's more going on, and
8
00:00:27,920 --> 00:00:31,070
there's some shadows on the ground here, for example.
9
00:00:31,070 --> 00:00:34,060
And so, it's not as obvious at the bottom of the image, but it's still there.
10
00:00:34,060 --> 00:00:37,720
And I'd like to even out the overall tones for the photo.
11
00:00:37,720 --> 00:00:41,850
In most cases, I'll use the lens correction filter in order to brighten
12
00:00:41,850 --> 00:00:46,760
the corners and the edges to remove a vignetting effect.
13
00:00:46,760 --> 00:00:50,080
Because that's actually going to be changing pixel values in the image.
14
00:00:50,080 --> 00:00:54,720
And I do need to work directly on pixels when I'm working with the lens correction filter.
15
00:00:54,720 --> 00:00:58,230
I'll start off by making a copy of my background image layer.
16
00:00:58,230 --> 00:01:01,430
So I'll drag the thumbnail for that background image layer down to the create
17
00:01:01,430 --> 00:01:06,270
new layer at the bottom of the layers panel, and that will make a background copy.
18
00:01:06,270 --> 00:01:09,751
I can also rename this layer if I'd like, I'll go ahead, for example, and
19
00:01:09,751 --> 00:01:13,704
double-click on the name of my background copy layer and I'll just type vignette
20
00:01:13,704 --> 00:01:18,691
correction so that I know what that layer is there for.
21
00:01:18,691 --> 00:01:23,660
I can then press Enter or Return on the keyboard in order to apply that name change.
22
00:01:23,660 --> 00:01:28,145
I'll then choose Filter, followed by Lens Correction, from the menu, and that will
23
00:01:28,145 --> 00:01:32,915
bring up the lens correction dialog. I wont be making use of the Auto
24
00:01:32,915 --> 00:01:36,506
Correction options, so I'll just move directly to the Custom tab in the Lens
25
00:01:36,506 --> 00:01:40,439
Correction dialog, and the controls I'm interested in are in the Vignette section
26
00:01:40,439 --> 00:01:45,906
appropriately enough. The amount slider determines how strong
27
00:01:45,906 --> 00:01:48,846
an adjustment will be applied to the image, moving toward the right will
28
00:01:48,846 --> 00:01:52,031
brighten the edges of the image, where moving to the left will darken the edges
29
00:01:52,031 --> 00:01:56,270
of the image. I'll leave the amount value at a strong
30
00:01:56,270 --> 00:01:59,735
negative value so that we can see a stronger vignetting effect here, just so
31
00:01:59,735 --> 00:02:04,900
that we can just better see the effect of changing the mid point value.
32
00:02:04,900 --> 00:02:08,310
If I move the slider to the left, from mid point, you'll see that vignetting
33
00:02:08,310 --> 00:02:11,940
effect moves further into the image, and if I move over toward the right, you'll
34
00:02:11,940 --> 00:02:16,140
see that less of the image is being corrected.
35
00:02:16,140 --> 00:02:21,830
So in essence I'm defining the size of that vignette area, in terms of the adjustment.
36
00:02:21,830 --> 00:02:26,970
The correction will be applied. I'll go ahead and first fine tune the amount.
37
00:02:26,970 --> 00:02:29,285
I'll lighten the edges of the images obviously.
38
00:02:29,285 --> 00:02:31,680
Hopefully in this case. And I need to be careful, I need to pay
39
00:02:31,680 --> 00:02:35,012
attention to the image while I'm working because the vignetting is effecting not
40
00:02:35,012 --> 00:02:38,710
just the corners, but also the edges of the photo.
41
00:02:38,710 --> 00:02:42,238
And I can see the corners still have a little bit of a vignette effect, but the
42
00:02:42,238 --> 00:02:46,356
edge is getting quite bright. I can work with the mid point slider, in
43
00:02:46,356 --> 00:02:50,535
order to try to minimize that effect. In other words having the adjustment only
44
00:02:50,535 --> 00:02:54,618
effect the corners, but not the edges. I could draw the adjustment further into
45
00:02:54,618 --> 00:02:57,432
the photo. Or push it outward so that it's not
46
00:02:57,432 --> 00:03:01,100
effecting those edge areas. So now we can see that this portion of
47
00:03:01,100 --> 00:03:04,080
the photo is not being lightened quite as much.
48
00:03:04,080 --> 00:03:07,446
And actually right about there I think, it's not being effected at all, whereas
49
00:03:07,446 --> 00:03:12,700
that amount slider is still going to be relatively effective at adjusting the corners.
50
00:03:12,700 --> 00:03:16,720
So I can continue tinkering with those adjustment settings as needed, until I'm
51
00:03:16,720 --> 00:03:20,668
happy with the result. Once I feel I've achieved a good result,
52
00:03:20,668 --> 00:03:25,060
then I can simply click The okay button in order to apply that change.
53
00:03:25,060 --> 00:03:28,580
And because I used a separate layer to apply this effect I can also now turn off
54
00:03:28,580 --> 00:03:31,770
the visibility for that vignette correction layer in order to see the
55
00:03:31,770 --> 00:03:38,420
before version of the photo and I can turn it back on to see the after version.
56
00:03:38,420 --> 00:03:41,995
And I think this is a big improvement we evened out the overall tonality so we no
57
00:03:41,995 --> 00:03:45,070
longer have those strong dark corners.
