Sometimes you might need to measure the distance between two objects or two points in your image. And to do that, you'll want to choose to use the measure tool. That's hidden underneath the eyedropper tool. So press and hold down the eyedropper tool and scroll down to the Measure tool. It looks like a ruler, and the way it works is you click to start a point and drag out to end the line segment. So we have our starting and our end point. Notice the Options palette gives you some values for our (X,Y) coordinate of our starting point. It also gives me a value for the width and height based on how far we dragged from our starting point. And it also gives me a value for the angle that this line is at. So you see that with a negative number I am going downhill here. So it's obviously not a horizontal line. If you wanted to constrain in to a horizontal line, you would hold down the shift key where you click and drag. And of course that constrains in to a perfectly horizontal line. Or if you're more of a 45 degree angle, then it will constrain it to a perfectly 45 degree angle. And finally perfectly vertical. But if you're not holding down the shift key, of course you can create any angle you wish. D1 will give you the distance. And these values of course are measured in whatever units you have set in the ruler's preferences. D2 has to do if you use the measuring tool to create a protractor effect. So I will do that. I will create a protractor effect by passing back over the last end of my measurement tool, and hold down the Option key on the Macintosh or the Alt key on a Windows machine. And now I can drag out another line. And now my angle is giving me the value of the range here. That is the angle value. And D2 gives me the distance of my second line. Another cool feature that the measurement tool has, is it deposits the angle value in the rotate command. So notice that my image here is slightly not horizontal. So I need to make that a horizontal picture. I want my Porsche to be on a perfectly flat pavement. So I'm going to measure from the center of the tire here. I'm going to click and drag over to this tire center. And if I make a mistake, I will make a mistake on purpose - drag that out. I can always go back and click on the end-point and reposition that wherever you need. So that looks pretty good. You can see it has deposited an angle value of 6.5, and I can use that to correct this image and rotate it back. So it's perfectly horizontal looking. And I will go to Image menu>Rotate and I will choose Arbitrary. And notice that it has actually deposited that value right here. And I will just click OK. And you can see that my picture has now been rotated so that my Porsche is on a perfectly level horizon. So I can go ahead and crop away at that white background if I wish. Again just to mention these lines - they do not print and if you ever need to get rid of them, you can simply hit the clear button, and they will be off of your screen.
