I chose a how to use the content aware tool in Photoshop. This tool is handy if there is something in your picture that is distracting and it will fill it with elements around it similar to the clone tool, but faster and fills it smoothly. The first step was to create a new layer for the content aware tool to be applied. Then take the polygonal lasso tool and select neatly right around the pole that was distracting in the background. Then, go to Edit-> Fill, and select Content aware, and leave the settings at 100%. Then to remove the post it says to just use the lasso tool and select around it and do the same process to fill it with gravel.
