Step 2 - Scale the image selection that you chose in step 1
Alright, so with that selected, copy it (control/command + C) and paste it into a new document (File > New). The default settings will be fine, and click OK. At this point, you will want to resize the document to a smaller scale (or keep it huge, but the tutorial will work with smaller units, so you will have to adjust everything if you keep the image really big). I rescaled the image to a width of 1200 px (Image > Image Size...) put 1200 in for the width, and the height will scale appropriately, automatically. Before you go any further, name this layer "city".
Step 3 - Select the sky
The next thing to do is to select the sky. There are lots of ways to do this, but for this tutorial, I wanted to be quick, so I just grabbed the quick selection (or magic wand) tool "w", and painted the sky until I had it selected. The pen tool will give you more exact results, but you probably won't notice small mistakes further on because of the clouds that we will add later. Just try to get a good selection.
Step 4 - Isolate your buildings
Now you get to choose which buildings you want to apply the effect to. First, you are going to want to select the city instead of the sky, so go to Select > Inverse, and then take the marquee tool "m" and choose the buildings that you want. Hold down option when you click and drag (this will get rid of the selected city on either side of your buildings. You should arrive at something that looks like the following image.
Step 5 - Prepping for a new sky
With these buildings selected, copy them (control/command + c) and paste them into a new layer, right where they were before (nothing should look different, you've only moved the buildings to a different layer). Name this layer "buildings".
Now, in the layers palette, select the layer "buildings" (control/command + click on the layer "buildings"), and then turn of the visibility of the "buildings" layer, so you can see what you're doing.
Now go back to the "city" layer (which now is without the buildings that you moved). Then, fill the selection with the color of the sky (use the eye dropper tool "i" to select a blue color somewhere in the sky, and then, fill the selection with the paint bucket/fill tool "g"). You should come up with something like this.
