100:00:02,190 --> 00:00:05,370When

1
00:00:02,190 --> 00:00:05,370
When you want to adjust the overall luminosity in a photo, one of the more

2
00:00:05,370 --> 00:00:10,520
basic ways to approach that is through the brightness/contrast adjustment.

3
00:00:10,520 --> 00:00:13,942
This adjustment, as the name implies, allows you to adjust the overall

4
00:00:13,942 --> 00:00:17,940
brightness and contrast in a photo very easily.

5
00:00:17,940 --> 00:00:21,716
Of course, brightness/contrast is not quite as fast as simply applying auto

6
00:00:21,716 --> 00:00:25,732
tone or auto contrast from the Image menu, for example.

7
00:00:25,732 --> 00:00:29,892
But those automatic adjustments are actually best suited to a color image, so

8
00:00:29,892 --> 00:00:34,116
that we have all that color information that can be used in processing the image

9
00:00:34,116 --> 00:00:39,210
in order to improve overall contrast and tonality.

10
00:00:39,210 --> 00:00:42,906
But for any image, whether black and white or color, the brightness/contrast

11
00:00:42,906 --> 00:00:46,490
adjustment provides a very good and very basic way to approach the luminance

12
00:00:46,490 --> 00:00:51,479
values in your photo. This photo, for example, is obviously a

13
00:00:51,479 --> 00:00:54,383
little bit flat. To be sure, there is some contrast,

14
00:00:54,383 --> 00:00:57,505
obviously we can make out texture and details.

15
00:00:57,505 --> 00:01:00,640
We have a very dark door in the background here, and some bright light

16
00:01:00,640 --> 00:01:05,589
coming through the windows, but overall the image looks a little bit flat.

17
00:01:05,589 --> 00:01:08,445
And so, I'm going to add a brightness/contrast adjustment layer in

18
00:01:08,445 --> 00:01:11,330
order to improve the appearance of the image.

19
00:01:11,330 --> 00:01:14,570
And by adding an adjustment layer, as opposed to applying an adjustment

20
00:01:14,570 --> 00:01:19,500
directly to the pixel values in the image, I'll be working non-destructively.

21
00:01:19,500 --> 00:01:22,910
And that means, I'm preserving the original pixel values, and I can always

22
00:01:22,910 --> 00:01:26,140
go back and refine my adjustment at any time.

23
00:01:26,140 --> 00:01:29,668
So, I've clicked on the Create New Adjustment Layer button, the half black,

24
00:01:29,668 --> 00:01:33,960
half white circle icon at the bottom of the Layers panel.

25
00:01:33,960 --> 00:01:38,000
And then I'll choose Brightness/Contrast from the popup menu.

26
00:01:38,000 --> 00:01:41,510
That will add a brightness/contrast adjustment layer, and you can see that on

27
00:01:41,510 --> 00:01:46,780
the Properties panel, I now have sliders for brightness and contrast.

28
00:01:46,780 --> 00:01:50,308
In applying this adjustment, I'll generally start with whichever slider I

29
00:01:50,308 --> 00:01:54,510
feel is going to have the most significant impact on the photo.

30
00:01:54,510 --> 00:01:58,286
In this case, I think that's contrast. The image overall is not too bright or

31
00:01:58,286 --> 00:02:01,440
too dark, but the contrast is certainly lacking.

32
00:02:01,440 --> 00:02:04,779
So I'll start off with contrast. I can drag to the left, if I want to

33
00:02:04,779 --> 00:02:08,635
reduce contrast. Or, as I want to in this case, I can drag

34
00:02:08,635 --> 00:02:12,220
to the right in order to increase contrast.

35
00:02:12,220 --> 00:02:15,514
Once I feel that I have the contrast adjusted as I like it, I'll go ahead and

36
00:02:15,514 --> 00:02:19,524
refine the brightness. Here, moving to the left will darken the

37
00:02:19,524 --> 00:02:22,950
photo, and moving to the right will brighten the image.

38
00:02:22,950 --> 00:02:26,810
I'll fine tune the effect here. I don't want it to be too bright.

39
00:02:26,810 --> 00:02:28,760
Right about there looks to be pretty good.

40
00:02:28,760 --> 00:02:32,950
And then I can go back and fine tune the contrast, if I feel that I need to.

41
00:02:32,950 --> 00:02:35,986
Bear in mind, there was no detail in the windows, and so I'm really not concerned

42
00:02:35,986 --> 00:02:38,608
about that bright light in the background, and I'm not too concerned

43
00:02:38,608 --> 00:02:43,216
about detail in the door. I just want the overall image to have a

44
00:02:43,216 --> 00:02:46,288
good feel. Good contrast and an appropriate

45
00:02:46,288 --> 00:02:49,153
brightness level. And again, because I was using an

46
00:02:49,153 --> 00:02:53,224
adjustment layer, I can always return to that adjustment layer later and fine tune

47
00:02:53,224 --> 00:02:56,764
the effect, adjusting brightness and contrast if I feel that perhaps my

48
00:02:56,764 --> 00:03:02,660
initial adjustment was less than ideal. So as you can see, working with

49
00:03:02,660 --> 00:03:07,048
brightness/contrast is quite simple. We just have two sliders, and the names

50
00:03:07,048 --> 00:03:11,520
tell us very clearly what those sliders are going to do to our image.

51
00:03:11,520 --> 00:03:16,680
And so, all we need to do

太暗，但对比肯定是缺乏的。

32
00:02:01440——> 00:02:04779
所以我先对比。我可以拖到左边，如果我想

33
00:02:04779——> 00:02:08635
降低对比度。或者，我想在这种情况下，我可以把

34
00:02:08635——> 00:02:12220
为了适当增加对比度。

35
00:02:12220——> 00:02:15514

然后我可以回去调整对比度，如果我觉得我需要。
