I've taken the liberty of modifying your photo with the suggestions provided. The easy way to lighten/darken an area is by the use of the 'Graduation Tool', simple for me as I use CS5. Maybe not in your editor but can be found the excellent freeware photo editor Paint.Net.
Last year I took a photo from with the fountain behind me. This was the result.
