Have you ever taken an image and when you pull it up in Photoshop, you wish you had framed more of the sky, grass, or background in general? Here is a very simple, 3 step process, to help you easily extend parts of your image. For this basic tutorial, I am going to extend the right of side of this image of my daughter a little more, just to put her framed even more to the left of the photo.
Working in Photoshop CS6, I first select Image>Canvas Size, as shown below.
This will pull up a pop up box where you can change the size in either direction you want, vertical or horizontal. Since I want to extend the right side, I am boosting my width from 75.25 to 80. Then I select the arrow pointing to the left, to "pull the image over" and make more room on the right. Make sure your Canvas Extension Color is set to white, then hit OK.
Now you are left with an open white area on the right side of your image, or whichever area you chose to extend, as shown below.
Choose the Quick Selection tool from the toolbar on left of screen, making sure "Auto Enhance" is selected in the menu bar up top, then select only the white area that you are wanting to extend, by dragging the tool from corner to corner in that area.
From your keyboard, hit the delete key. When you do this, a "Fill" Dialogue box will pop up. Make sure the "Use" option is set to Content-Aware, then hit OK.
As you can now see, our white part of the image has been filled to match the areas close to the area.
Keep in mind that content aware pulls from the closest areas of the area you are wanting to extend. So if we tried extending from the left, we wouldn't have any area to work with using this technique, because our subject is already so close to the edge. But this simple technique works wonderful when you want to extend small parts of your image that have a consistent pattern or background.
The below images show the before and after, with a little more background on right side of the image.
