1
00:00:00,800 --> 00:00:03,733
In this lecture, we'll explore
image cropping.
2
00:00:03,733 --> 00:00:08,600
We can use the crop overlay tool
to crop and change the angle of an image.
3
00:00:08,700 --> 00:00:13,400
For this exercise load image BMW 005. jpg.
4
00:00:13,500 --> 00:00:15,966
If you'd like to follow along,
5
00:00:15,966 --> 00:00:19,300
an easy way to find it
is to click the BMW collection
6
00:00:19,400 --> 00:00:20,966
and then open the image from here.
7
00:00:20,966 --> 00:00:26,333
To get started, click
the crop overlay tool to activate it.
8
00:00:26,400 --> 00:00:27,733
You'll see a number of options
9
00:00:27,733 --> 00:00:31,066
appear in your adjustments panel
as soon as you've clicked it.
10
00:00:31,166 --> 00:00:36,933
For now,
make sure the lock here is unlocked
11
00:00:37,000 --> 00:00:40,266
and that your angle is set to 0.00.
12
00:00:40,433 --> 00:00:43,766
We'll explore these settings in a moment.
13
00:00:43,833 --> 00:00:46,833
You'll notice on your image
that a grid has appeared.
14
00:00:47,100 --> 00:00:51,100
The grid helps us use the cropping tool
effectively.
15
00:00:51,200 --> 00:00:53,533
Let's start off by doing a basic crop
16
00:00:53,533 --> 00:00:57,700
and isolating only the car
from the rest of the background.
17
00:00:57,766 --> 00:01:00,633
To do so, hold your left mouse button down
18
00:01:00,633 --> 00:01:06,333
and drag out a crop region.
19
00:01:06,400 --> 00:01:09,133
You'll notice that the image is now
isolated in a crop
20
00:01:09,133 --> 00:01:14,700
box in the area that will be cropped
out is dimmed behind it.
21
00:01:14,766 --> 00:01:17,133
We can readjust the size of the crop box
22
00:01:17,133 --> 00:01:27,433
by pulling each handle.
23
00:01:27,533 --> 00:01:29,733
At the moment,
you'll notice that the crop region
24
00:01:29,733 --> 00:01:34,066
that we've drawn is quite flexible
in terms of width and height.
25
00:01:34,166 --> 00:01:36,833
That's
because we have not constrained the aspect
26
00:01:36,833 --> 00:01:40,900
ratio by clicking this lock here.
27
00:01:40,966 --> 00:01:42,933
I've clicked the lock and let's see,
28
00:01:42,933 --> 00:01:47,500
we want to constrain this
to a specific print size.
29
00:01:47,566 --> 00:01:51,200
Click right over here
and a menu will appear
30
00:01:51,300 --> 00:01:53,700
and we can go ahead and select
any one of these.
31
00:01:53,700 --> 00:01:57,366
I'll go in, select five by seven,
and now you'll see that
32
00:01:57,366 --> 00:02:08,366
when I pull the crop handles,
the aspect ratio is maintained.
33
00:02:08,433 --> 00:02:08,800
So this
34
00:02:08,800 --> 00:02:13,000
option works
well if you want to print a specific size.
35
00:02:13,066 --> 00:02:16,500
If you'd like to redraw the crop region,
you can click on the crop
36
00:02:16,700 --> 00:02:19,666
frame tool over here
37
00:02:19,666 --> 00:02:21,666
and redraw it.
38
00:02:21,666 --> 00:02:32,333
I'll go ahead
and unlock this for a second.
39
00:02:32,400 --> 00:02:33,900
And as you can see, our crop
40
00:02:33,900 --> 00:02:37,900
area has been readjusted.
41
00:02:37,966 --> 00:02:40,966
If you'd like to reset the crop region
you've drawn.
42
00:02:41,100 --> 00:02:44,100
Simply click the reset button down here.
43
00:02:44,100 --> 00:02:49,033
We can also use the angle slider here
to change the angle of an image.
44
00:02:49,133 --> 00:02:54,433
Let's go ahead and redraw our crop region.
45
00:02:54,533 --> 00:02:57,533
There's two ways
to change the angle of this image.
46
00:02:57,533 --> 00:03:03,400
We can either use
the angle slider over here
47
00:03:03,500 --> 00:03:06,400
or just put that back to zero
48
00:03:06,400 --> 00:03:09,966
or position
your cursor outside of the crop area.
49
00:03:10,033 --> 00:03:18,633
Hold your left mouse button down
and drag the image up and down.
50
00:03:18,700 --> 00:03:19,533
Another tool
51
00:03:19,533 --> 00:03:23,033
we have here at our disposal
is the straightened tool found here.
52
00:03:23,100 --> 00:03:24,900
To activate it, click on it.
53
00:03:24,900 --> 00:03:26,933
Also, press the reset button.
54
00:03:26,933 --> 00:03:30,466
Just remove the crop area
and go back to our original image.
55
00:03:30,566 --> 00:03:34,466
The next thing we need to do
to straighten a specific object,
56
00:03:34,466 --> 00:03:39,366
it needs to be straightened
in reference to another object.
57
00:03:39,433 --> 00:03:43,233
So for example,
if we know that this truck is parked
58
00:03:43,233 --> 00:03:47,100
on a driveway
at a 90 degree angle to this building,
59
00:03:47,166 --> 00:03:50,466
it's a good indication
that that's a perfectly straight line.
60
00:03:50,533 --> 00:03:54,666
So let's go ahead and use this reference
point to straighten our image out.
61
00:03:54,733 --> 00:03:57,700
Draw the line starting here
62
00:03:57,700 --> 00:04:02,400
and go up to hold your left
mouse button down and just drag up
63
00:04:02,466 --> 00:04:04,800
and you'll notice
that the image straightens out.
64
00:04:04,800 --> 00:04:10,000
Based on that reference point, I'll go
ahead and reset that as another example.
65
00:04:10,033 --> 00:04:13,466
I'll go ahead and select
the straight into again,
66
00:04:13,533 --> 00:04:14,433
and I'll draw a
67
00:04:14,433 --> 00:04:17,466
line from the bottom of the front wheel
68
00:04:17,500 --> 00:04:21,700
to the rear wheel.
69
00:04:21,766 --> 00:04:24,600
Now it's straightening the image
using that reference point.
70
00:04:24,600 --> 00:04:28,400
Now, remember, to apply this change,
you'll need to click the done button.
71
00:04:28,500 --> 00:04:32,300
If you don't click the done button,
this crop will not be applied.
72
00:04:32,366 --> 00:04:34,133
So I'll go ahead and reset again.
73
00:04:34,133 --> 00:04:37,133
There's a checkbox here
called Constrained to Image,
74
00:04:37,166 --> 00:04:39,866
and this checkbox is actually tied
to the lens
75
00:04:39,866 --> 00:04:42,866
correction panel,
which we'll be discussing a bit later.
76
00:04:42,900 --> 00:04:46,133
For now,
just know that it ensures our crop area
77
00:04:46,200 --> 00:04:51,100
constrains to our entire image
when we apply a lens distortion.
78
00:04:51,200 --> 00:04:53,833
As an example,
I'll just scroll down to the lens,
79
00:04:53,833 --> 00:04:58,300
this lens correction area,
80
00:04:58,400 --> 00:05:00,900
and I'm going to create
a bit of a distortion there.
81
00:05:00,900 --> 00:05:03,300
You'll notice
when the distortion is created,
82
00:05:03,300 --> 00:05:09,133
there's a white background
there behind the image.
83
00:05:09,233 --> 00:05:11,400
So if I click constrain to image,
84
00:05:11,400 --> 00:05:16,233
you'll see that the crop region fits
neatly within that, within the image area
85
00:05:16,300 --> 00:05:20,333
and cuts out any of that white area
behind the image.
86
00:05:20,400 --> 00:05:20,600
Okay.
87
00:05:20,600 --> 00:05:23,733
And that's how we work with the crop
adjustment panel
88
00:05:23,733 --> 00:05:26,733
in all the settings that pertain to it.
89
00:05:26,733 --> 00:05:29,400
If you'd like to keep the changes,
click done.
90
00:05:29,400 --> 00:05:32,000
If you'd like to reset the image
back to its original
91
00:05:32,000 --> 00:05:35,000
click reset,
I'll go ahead and click reset.
92
00:05:35,100 --> 00:05:37,600
Now that we're finished
with the crop tool,
93
00:05:37,600 --> 00:05:40,733
deactivate it
by clicking on the crop tool icon again.
