00:00:02,652 --> 00:00:08,350
Let's take a quick look of how
to set your scanner settings.

2
00:00:08,350 --> 00:00:11,622
That is, to set it
for a particular dpi.

3
00:00:11,622 --> 00:00:15,260
So what you do is you
first take a preview.

4
00:00:15,260 --> 00:00:19,640
At least on my scanner, this
is the software that I see.

5
00:00:19,640 --> 00:00:22,970
Yours might be different,
but the idea is the same.

6
00:00:22,970 --> 00:00:23,910
So we get a preview.

7
00:00:23,910 --> 00:00:26,110
This is what my
screen looks like.

8
00:00:26,110 --> 00:00:32,150
And what I decided to do is scan
only this particular portion

9
00:00:32,150 --> 00:00:37,410
to get final images of
this particular device.

10
00:00:37,410 --> 00:00:38,850
So I did that.

11
00:00:38,850 --> 00:00:39,980
That's how it looks.

12
00:00:39,980 --> 00:00:43,430
And when I press
scan, I am asked

13
00:00:43,430 --> 00:00:44,920
whether I want to save it.

14
00:00:44,920 --> 00:00:49,330
And I did intend to
save it at 72 dpi.

15
00:00:49,330 --> 00:00:53,040
That's the first scan
that I decided to take.

16
00:00:53,040 --> 00:00:58,550
And then I went through a
whole series of various scans.

17
00:00:58,550 --> 00:01:02,040
And let's look at
them all together.

18
00:01:02,040 --> 00:01:12,850
The various scans were 72 dpi;
300; 2,400; up to 6,400 dpi.

19
00:01:12,850 --> 00:01:15,140
And let's see the difference.

20
00:01:15,140 --> 00:01:17,750
Here it is slightly
enlarged, sort

21
00:01:17,750 --> 00:01:21,580
of trying to keep the same
visuals for you to compare.

22
00:01:21,580 --> 00:01:25,420
I'm starting to see that
the 72 dpi is definitely

23
00:01:25,420 --> 00:01:27,350
losing clarity.

24
00:01:27,350 --> 00:01:28,940
The others look OK.

25
00:01:28,940 --> 00:01:32,660
And as we increase
the images more so,

26
00:01:32,660 --> 00:01:36,640
we're starting to see
this one breaking down.

27
00:01:36,640 --> 00:01:39,900
And it's starting
to really show up

28
00:01:39,900 --> 00:01:42,120
as we increase the image size.

29
00:01:42,120 --> 00:01:45,830
So you see as you
increase the resolution,

30
00:01:45,830 --> 00:01:48,560
you get more clarity
in the image.

31
00:01:48,560 --> 00:01:52,479
You're getting more
information for the most part.
