Using a photo of a sunset that I took myself, and I gave the sky a painted effect by using the mix brush. The trees and ground are also painted, but on a separate layer, so they would remain distinct. The contrast of sky in the painted photo has been increased, and given texture by using an emboss filter as shown in the video. Of the assignments thus far, this is my favorite.

The effect of this technique is nice, but it takes a very long time, and it was hard to tell which parts had been painted as they were the same color as the background. I had to turn off the visibility of the bottom layer every few strokes to see what I was doing. That may have been a problem because the sky did not have much distinct detail in the first place.
