I started off with a curves adjustment and used the basic s curve to enhance the picture. Next I applied a levels adjustment but it only made the white house in the back super bright and wasn't as visible, it also darkened the shadows too much. Finally I tried applying a couple of grunge textures. The first one was of no use to me because the grunge image was too small. The second one was too light and created a similar problem to the one i had with the levels adjustment. Finally I found a third one that was the right size and simple but it gave my picture a yellowish tint I didn't like so I settled on only doing a curves adjustment.
