Inertia

Photo manipulation, as if you couldn't tell. First attempt at faking a tilt-shift. I started with the tutorial, but it didn't work, so I made a few modifications. I took this photo myself. Original:

Something's not quite clear to me. After adding and adjusting the mask layer, are you saving just that mask layer, or the entire .png? I did that, but I couldn't "see" the file I'd saved when I tried to apply the AlphaMask plugin. I think I may have found my problem with finding the file, but I still am unclear if the mask layer is to be saved separately or with the rest of the layers.
