AERIAL LANDSCAPE

Step 1

Open a new canvas, 300 x 300, 72 dpi.  Hit 'D' key to set colors to default.  Go to Filter/Render/Clouds.

Step 2

Go to image/adjustments/curves.  Make your curve like the one on the left.

 

Step 3

Go to Select/Color Range. The setting you enter here depends on the density of your cloud mass (the clouds filter never applies the same way twice).  I had to enter a value of 200 for the fuzziness.   Bear in mind we want an aerial landscape, so we need some white areas and dark areas.
 

You should now have something like this.
 

Step 4

Go to Select/Feather and enter a value of 2.  Go to Filter/Render/Clouds.  Don't deselect.
 

Step 5

Go to Select/Inverse.  Filter/Render/Difference Clouds.
 

Step 6

Go to Image/Adjustments/Hue&Saturation.  Check the colorise box and select a green color.  The hue etc again depends on the density of your cloud.
 

Step 7

Filter/Noise/Add Noise (Uniform/Monochromatic, 20).  Then Filter/Texture/Craquelure.
 

Step 8

Go to Select/Inverse.  Image/Adjustments/Hue&Saturation and select an aqua color.

Step 9

Go to Filter/Distort/Ocean Ripple and enter settings of 2 and 10 respectively.

The end result will vary (because of differences in the cloud filter at any given time and because of differences in the hue, saturation and brightness options).  Here is another example.
