In this image there were a significant amount of dark spots that I wanted to lighten up somewhat. The street in the bottom left corner was lightened to the point where it was easier to see detail. I tried to keep the clouds in the top right from disappearing and lightening too much. These effects were reached through a curves adjustment. The image was made more vibrant by using the channel mixer with some slightly different numbers than usual as the greens in the windows were becoming too green. Lastly I used the dodge tool to brighten up the trees so that they didn't look muddy and dull.
