In order to make this straight we will have to call upon the very powerful transform tools. Indeed we are going to use this extensively to correct the image. Firstly, create a duplicate layer (CMD/CTRL J). Using the Marquee tool, select a small area that encompasses the horizon and then select EDIT/TRANSFORM/ WARP. By 'grabbing' the points on the grid presented you can move different parts of the selection up and down. This takes a bit of trial and error. The distortion on this lens is such that I had to select the middle section again and adjust this to get it right. Also note that the lens correction facility in ACR might have a pre-set correction, it depends upon the lens in question.

The next thing I want to tackle are the rocks appearing in the left-hand side of the frame. I can use the Healing Brush tool, but this can take a little time. I have found that making a selection with the lasso tool, with a small feather and then using EDIT/TRANSFORM/SCALE works very well. What I have done is to increase the size of the selection (eg SCALE) to the left so that I effectively drag the rocks off the canvas.

The next thing I want to do is to give a lot more space to the bottom of the image. The main rocks are not well placed and too dominant as they stand. Effectively I need to increase the size of the canvas. A quick way of doing this is to use the CROP tool and grab the bottom of the selection and drag it down, revealing the new addition to the canvas. Hit Enter to commit this change.

The next thing to do is to extend the image into this area of the canvas. Again I will use the Marquee tool and make a selection right across the bottom of the image. Next use EDIT/CONTENT AWARE SCALE and grabbing the bottom of the selection pull it down as far as necessary.
