Fix a crooked image in Gimp 2.8

So you took a photo, it's not a great image, but it's not a bad one either. However, the angle is just way off. Today we use Gimp to adjust the angle, and remove some clutter from the photo.

We can accomplish this process in about four easy steps. We will need the Rectangle Select Tool, the Rotate Tool, then Image crop to selection, these are all circled in the below diagram.

You can click this image to enlarge. Everything you need should be circled.
 O.K. first open the crooked image that needs to be straightened out in Gimp. Now click on the "Rotate Tool", and then click on the image. A grid should appear and a new box with a slider, slide the slider till the image is in it's desired position. If you did this correctly the image should now be cocked at an odd angle, but your line of focus should now be straight and even.

Here's the crooked image, notice the angle and also the clutter of wires on the floor.After we edit this in Gimp, the image will have a straight center of focus, and when we crop the image we will have removed the mess of wires on the floor, giving us a cleaner more centered image.

Now click on the "Rectangle Select Tool", figure out how you want to center the image, and then start at the top right of your center point and drag it down to the bottom left. Be careful that you don't get any of the transparent background in the corners when you drag it.

Now go to Image, Crop To Selection, and your done ! To save the image go to File, export, then name your new image and save it as filename_edit.jpg or whatever you want to name your new and improved image.

The image now has a proper angle, the ugly wires were removed when we cropped the image, and the focus of attention is on the subject matter.
 Hope this helped, thanks for reading, and happy photographing !

Bloggers note : I was doing some housework the other day, and just snapping random shots with my new camera trying to learn some of the different features. After I hung up these new curtains, the cat was really curious about the alien hanging out in his favorite window. I just snapped a quick shot, and the angle was terrible but I thought it was a really cute photo of the cat. It  gave me a great excuse to write a tutorial today though. Hoped it helped.
