Starry Sky

I found a tutorial showing how to create a starry night in Photoshop. http://www.photoshopessentials.com/photo-effects/starry-sky/. I took a day photo of a tree line and converted it to night then followed the steps in the tutorial. This was enjoyable and the only problem I ran into was when I tried flattening the psd. The image looked a little different. I redid the layer with the starry effect but used more blur and that seemed to solve the problem. Just for grins and giggles I added a shooting star.
