Hello, this is Rob here from Rob cup calm and in this video I'm going to be talking about rotating images. Sometimes you just need to straighten up images, it looks like the camera wasn't dead straight to the horizontal lines in the image. And here for example, we have a building that is noticeably sloping down to the right, so in the photograph will look a lot better if all the lines were straight. And there's several ways of doing this. Of course with the crop tool, you can crop the image like this and then you can drag the outside so you rotate the crop a little bit to try and be parallel with the horizontal lines. You can go to Image Rotation and this is how you rotate an image, turn it upside down or to the left or To the rights and arbitrary here, you guess the angle which is clockwise or counterclockwise.

But there's another tool here, if you keep your finger down on to the eyedropper tool, you can get the ruler tool. Now the ruler tool is used for measuring pixels, you drag it from one end to the other, and you have the length of the line and the width and height of the line. You also have the angle of the line. You can drag this as many times as you want, and you can clear the measurements, but I'm going to drag this from one end of that line of bricks to the other. And I'm sloping down with the bricks so we can measure that angle and as you can see that angle is minus 2.1 degrees. And now if you go to Image Rotation, arbitrary you get the exact angle of that line.

So you know if you Click OK now that the image is going to be perfectly straightened up, so all you've got to do is now crop in a normal way, no need to rotate the crop at all. I will try and put as much of the image as we can without going over any of the edges. And then if we double click there is our image rotated a little bit so it's fully straightened up and looks much better. Okay, I hope you enjoyed that. This is Rob from Rob cabin.com. I'll see you in the next video.
