In this exercise, I'm going to show you how to use the Crop tool in combination with the Rotate View tool. The great thing about the Rotate View tool is it allows you to preview the angle of rotation before you apply it. I have opened this image called Crooked Pisa number 2.jpg found inside that same 06_crop_straight folder. This image comes to us from Moras Usanta of the Fotolia image library. Like so many Pisa images these days, it's also a little bit crooked, but it's not all that crooked. You can see that we have a slight angle of this building here, and we have some angle associated with the rungs holding up this rail.
So I'm not sure, I just want to go ahead with a Crop tool without knowing in advance sort of how it ought to look. So here is what I recommend you to do. Press-and-hold the R key in order to get the Spring-Loaded Rotate View tool, and then click and drag to rotate the image pretty slightly as it just so happens. Then when you think the image has rotated properly, go ahead and release. But I want you to look in the upper-left corner of my window here. Now you can see in the Option bar that the Rotate Angle is -1 degree.
Now something to note about that measurement is its not very accurate. You don't get a decimal, and also it doesn't really switch to 2 degrees until you hit it. So everything seems around down, I just want you to be aware of that. All right, I'm going to go ahead and release both the mouse button and the key. Now I'm going to switch to the Crop tool, just by clicking on it or pressing the C key. As I drag with the Crop tool, you can see that I get an automatically rotated crop boundary. Well, it's not really. It's straight inside of the rotated image.
So everything is going to be rotated in kind in this view. Then we're going to rotate the crop boundary back. Now I'm going to click on the I here in order to bring up the Info panel, and notice the A value. This angle value is more accurate than the one we were seeing a moment ago. So I'm just going to use it as kind of a second check. I'm going to drag outside the crop boundary until those edges appear to be straight. I think that's happening. It's hard to tell exactly, but I think that's happening at about though this point, which would be an Angle value of 1. 5 degrees and that make sense, because after all we saw an angle of -1 degrees and I told you it rounds down and so that is up, when it's negative.
But anyway, it rounds to 1 as opposed to 2 and +1.5 seems to correlate. All right. Let's go ahead and zoom out a little. Photoshop has gone ahead and reset my Shield Color. So I'm gong to switch that to white, again like so and click OK, and then change the Opacity value to something like 35 degrees. So it's not covering up quite so many very important details here. I'll drag this corner-handle down to perhaps this location, and this corner-handle up to about here.
I'm trying to keep as much of the image as I can of course. That seems to have given me a snap to the right-side of the image. I'm trying to snap to the left side, but I'm not getting any luck there. So I'll just drag down a little bit until I achieve this result here. It looks pretty good, maybe drag up a little, and maybe drag this corner-handle, so I don't end up revealing a wedge. I think that's enough work. Zoom in maybe a little bit, so I can better see what I'm doing. Now I'm going to press the Enter key or the Return key on the Mac in order to apply that crop.
What's interesting here is the image is still crooked, by virtue of the fact that we're still inside the Rotated View. So, the next thing you have to do is escape the Rotated View by pressing the Escape key and now we seem to be good to go. I think we do have a straight version of the image, a little bit of a wedge. My goodness, we should have to clean those up, don't we, and I'll go ahead and select that using the Rectangular Marquee tool. So I press M to get the Rectangular Marquee, selected this region. Press the Backspace key, Delete on the Mac, make sure Use is set to Content-Aware, click OK and click off that selection.
We not to zoom in to see if it did exactly the job we wanted to do. We've got a little bit of an edge there. But I tell you what, that is so much easier, than it used to be in the old days that automatic selection healing, that we now have in CS5. So there we are. We were able to preview the angle of rotation using the Crop tool in combination with Rotate View.
