100:00:02,330 --> 00:00:05,441When

1
00:00:02,330 --> 00:00:05,441
When it comes to restoring old photographs one of the biggest challenges

2
00:00:05,441 --> 00:00:10,000
that we face is the raw material that we're actually working with.

3
00:00:10,000 --> 00:00:13,770
Obviously in many cases older photographs are going to be faded, or other wise

4
00:00:13,770 --> 00:00:17,410
damaged, and we'll want to address those issues.

5
00:00:17,410 --> 00:00:21,430
But before we even get started with that it's important to give yourself the best

6
00:00:21,430 --> 00:00:25,450
starting point possible. And that means working with the best

7
00:00:25,450 --> 00:00:29,110
source image possible. Obviously, if you had multiple copies of

8
00:00:29,110 --> 00:00:33,170
the same photo, you would choose the one that was in the best condition.

9
00:00:33,170 --> 00:00:36,810
But it's also important to choose the appropriate source.

10
00:00:36,810 --> 00:00:39,640
You want to start with the best original possible.

11
00:00:39,640 --> 00:00:43,138
And that means not just picking the best version, if you have multiple copies of

12
00:00:43,138 --> 00:00:47,830
an image for example, but that you start with the best source material.

13
00:00:47,830 --> 00:00:51,426
And that means using an original transparency if you're working with

14
00:00:51,426 --> 00:00:57,020
slides, a film negative, or even a glass plate for certain older images.

15
00:00:57,020 --> 00:01:00,901
The last option you'll want to consider is a photographic print.

16
00:01:00,901 --> 00:01:04,681
And that's because a print contains far less information than the original

17
00:01:04,681 --> 00:01:09,750
transparency, generally around 10% of that original information.

18
00:01:09,750 --> 00:01:12,786
Of course in some cases you'll only have the print as an option and if that's your

19
00:01:12,786 --> 00:01:16,958
only option then that's certainly what your going to need to work with.

20
00:01:16,958 --> 00:01:19,902
But bear in mind the better the original the easier your process is going to be

21
00:01:19,902 --> 00:01:23,770
and the better the quality of your final result.

22
00:01:23,770 --> 00:01:27,589
With an analog original, a print, a slide or negative, you're going to need to get

23
00:01:27,589 --> 00:01:31,777
that into the computer. And that means scanning that original in

24
00:01:31,777 --> 00:01:35,653
a way that give you optimal quality, the maximum amount of information with which

25
00:01:35,653 --> 00:01:39,474
to work. Whether you're scanning for yourself or

26
00:01:39,474 --> 00:01:42,440
sending your originals out to someone else to be scanned.

27
00:01:42,440 --> 00:01:46,640
It's important which settings are actually used for that scanning.

28
00:01:46,640 --> 00:01:48,900
To start with, you'll want to consider resolution.

29
00:01:48,900 --> 00:01:53,652
When we're scanning a transparency, a glass plate, a film negative, or a slide,

30
00:01:53,652 --> 00:01:59,770
you'll want to scan at the maximum optical resolution of the original.

31
00:01:59,770 --> 00:02:03,918
If you only have a print available, then I recommend scanning at around 600 pixels

32
00:02:03,918 --> 00:02:07,343
per inch. This particular image has a number of

33
00:02:07,343 --> 00:02:11,390
problems, including a problem related to resolution.

34
00:02:11,390 --> 00:02:14,083
So, let's explore the various problems with this image.

35
00:02:14,083 --> 00:02:17,203
So that we can get a better sense of what we'll actually want to do when scanning

36
00:02:17,203 --> 00:02:22,237
our originals that we plan to restore. I'll start off by choosing Image, Image

37
00:02:22,237 --> 00:02:26,515
Size from the menu and we can see that this is a relatively small image it was

38
00:02:26,515 --> 00:02:32,422
scanned at 300 pixels per inch. And the original is apparently about 5

39
00:02:32,422 --> 00:02:36,245
inches by 4 inches. That's a very small scan, and it's not

40
00:02:36,245 --> 00:02:39,620
going to give us very much information to work with.

41
00:02:39,620 --> 00:02:44,110
If this had been a print, then we would want to scan it around 600 pixels per inch.

42
00:02:44,110 --> 00:02:47,344
And if it was an original transparency, then we would want to scan at the maximum

43
00:02:47,344 --> 00:02:51,630
optical resolution of the scanner. And for many scanners, that range is

44
00:02:51,630 --> 00:02:55,530
anywhere from around 2000 pixels per inch for a flat bit scanner up Up to around

45
00:02:55,530 --> 00:03:01,150
4000 pixels per inch, for film scanner. But check the specifications for your

46
00:03:01,150 --> 00:03:06,680
scanner, or the service provider that you're using to find out what that value is.

47
00:03:06,680 --> 00:03:10,870
Next we'll want to consider the mode in which we are actually scanning.

48
00:03:10,870 --> 00:03:13,280
I'll go to the Image menu, and choose mode.

49
00:03:13,280 --> 00:03:17,290
And you can see that this image was scanned in, in a Gray Scale mode.

50
00:03:17,290 --> 00:03:20,440
And that makes a lot of sense because the original here is in fact gray scale,

51
00:03:20,440 --> 00:03:23,990
there is not color information in the original.

52
00:03:23,990 --> 00:03:28,140
However, I recommend scanning in the RGB color space.

53
00:03:28,140 --> 00:03:31,550
In most cases, that's not going to provide a huge advantage, and in fact, it

54
00:03:31,550 --> 00:03:35,670
triples the size of your fil. But it can be helpful for images that

55
00:03:35,670 --> 00:03:39,355
have any degree of color shift or fading, because it means that we're getting the

56
00:03:39,355 --> 00:03:44,230
maximum amount of information out of the original.

57
00:03:44,230 --> 00:03:47,714
We also want to consider the bit depth at which we're scanning and you can see that

58
00:03:47,714 --> 00:03:51,730
this image was scanned in at 8 bits per channel.

59
00:03:51,730 --> 00:03:55,456
Whenever possible, I recommend scanning at 16 bits per channel because this gives

60
00:03:55,456 --> 00:03:59,065
us much smoother gradations in our scanned original.

61
00:03:59,065 --> 00:04:03,610
And that gives us much greater flexibility when we're optimizing the image.

62
00:04:03,610 --> 00:04:07,972
And that's especially important when it comes to working with old and faded images.

63
00:04:07,972 --> 00:04:11,300
Because it's quite likely that we're going to need to apply relatively small

64
00:04:11,300 --> 00:04:16,075
adjustments to those images. Your scanner might not offer options that

65
00:04:16,075 --> 00:04:19,740
are referred to as 8 bits per channel or 16 bits per channel.

66
00:04:19,740 --> 00:04:23,880
And that's because, very often, scanners will refer to the final overall bit depth

67
00:04:23,880 --> 00:04:28,174
for an RGB image. An RGB image contains three channels and

68
00:04:28,174 --> 00:04:33,868
therefor, an 8 bit per channel scan would be referred to as a 24 bit scan.

69
00:04:33,868 --> 00:04:39,620
And a 6 bit per channel scan would be referred to as a 48 bit scan.

70
00:04:39,620 --> 00:04:43,154
Regardless, I recommend scanning at the highest bit depth offered by your

71
00:04:43,154 --> 00:04:48,840
scanner, and that's generally going to be 16 bits per channel, or 48 bit.

72
00:04:48,840 --> 00:04:52,726
All of these considerations are aimed at making sure you have the maximum amount

73
00:04:52,726 --> 00:04:56,551
of high quality information in your original scan.

74
00:04:56,551 --> 00:05:01,260
Which will give you maximum flexibility and optimal quality in your final image.

如果您只有一个打印，然后我建议在600像素

32
00:02:03918——> 00:02:07343
每英寸扫描。这一特定的形象有一些

33
00:02:07343——> 00:02:11390
问题，包括相关的解决的问题。

34
00:02:11390——> 00:02:14083
所以，我们探讨这一形象的各种问题。

35
00:02:14083——> 00:02:17，203
以便我们能更好地了解我们真正想做的

扫描时36
00:02:17203——> 00:02:22237
我们的份，我们计划恢复。我会先选择图像，图像

37
00:02:22237——> 00:02:26515
大小从菜单中我们可以看到，这是一个比较小的图像，这是

38
00:02:26515——> 00:02:32422
300像素每英寸扫描。和原来的显然是5

39
00:02:32422——> 00:02:36245
英寸4英寸。这是一个非常小的扫描，而不是

40
00:02:36245——> 00:02:39620
会给我们非常多的信息工作。

41
00:02:39620——> 00:02:44110
如果被打印，然后我们想扫描周围的每英寸600像素。

42
00:02:44110——> 00:02:47344
如果它是一个原始的透明度，那么我们就要扫描的最大

43
00:02:47344——>扫描仪的光学分辨率00:02:51630
。和许多扫描仪，范围

44
00:02:51630——> 00:02:55530
大概在2000像素每英寸平板扫描仪上一点达

45
00:02:55530——> 00:03:01150
每英寸4000像素，胶片扫描仪。但检查规范你的

46
00:03:01150——> 00:03:06680
扫描仪，或服务提供者，你用发现的价值是什么。

47
00:03:06680——> 00:03:10870
接下来我们要考虑，我们实际上是扫描模式。

48
00:03:10870——> 00:03:13280
我去图像菜单，选择模式。

49
00:03:13280——> 00:03:17290
你可以看到这个图像进行扫描，在灰度模式。

50
00:03:17290——> 00:03:20440
，很有意义，因为这里原来是事实上的灰度，

51
00:03:20440——> 00:03:23990
在原来的颜色信息是不存在的。

52
00:03:23990——> 00:03:28140
然而，我建议扫描的RGB颜色空间。

53
00:03:28140——> 00:03:31550
在大多数情况下，这是不会提供一个巨大的优势，事实上，它

54
00:03:31550——> 00:03:35670
三您的文件的大小。但它可以帮助图像

55
00:03:35670——> 00:03:39355
有任何程度的变色或褪色，因为它意味着我们得到的

00:03:39355——> 00:03:44230
最大信息量从原来的57
00:03:44

，230——> 00:03:47714
我们也要考虑点的深度，我们扫描，你可以看到

58
00:03:47714——> 00:03:51730
这图像扫描的每通道8位。

59
00:03:51730——> 00:03:55456
只要有可能，我建议在每通道16位扫描因为这给

60
00:03:55456——> 00:03:59065
我们更平滑的层次我们扫描原始。

61
00：03:59065——> 00:04:03610
，给了我们更大的灵活性，当我们优化图像。

62
00:04:03610——> 00:04:07972
，尤其重要的是当它涉及到旧褪了色的图像。

63
00:04:07972——> 00:04:11300
因为很有可能，我们需要适用于比较小的

64
00:04:11300——> 00:04:16075
调整图像。你的扫描仪可能无法提供的选项，

65
00:04:16075——> 00:04:19740
称为每通道或每通道16位8位。

66
00:04:19740——> 00:04:23880
这是因为，通常，扫描仪将最终的全局位深度

67
00:04:23880——> 00:04:28174
为RGB图像。一个RGB图像包含三通道和68


00:04:28174——> 00:04:33868
因此，8位/通道扫描会被称为一个24位的扫描。

69
00:04:33868——> 00:04:39620
和6位/通道扫描会被称为一个48位的扫描。

70
00:04:39620——> 00:04:43154
不管，我建议你

扫描在71
00:04:43154提供了最高的位深度——> 00:04:48840
扫描仪，而这一般将每通道16位，或48位。

72
00:04:48，840——> 00:04:52726
所有这些考虑的目的是确保你有最大数量

高质量信息的扫描。

74
00:04:56551——> 00:05:01260
