To straighten the image in Photoshop, click on the Crop tool, move the cursor to a corner of the image until it becomes curved, then drag up or down to rotate. Click the check mark at the top of the screen to apply. To remove extraneous objects, such as the wire at the very top of the image, use the Lasso tool to loosely select the object to be removed. Then go to Edit > Fill, choose Content Aware in Contents field and click OK. Repeat as needed. When finished, save your work.
