Now we’ll duplicate the ‘blocks’ of forms that we made. Select all the layers of the block and click Edit > Free Transform > Flip Horizontal. Duplicate three times, as in this image (two blocks above and two below). This will make the composition symmetrical.
Now let’s add in the composition’s central element. Import moon.jpg from the cover CD and use the Elliptical Marquee Tool to cut out the background. Duplicate the moon and click Image > Adjustments > Gradient Map, choose the Black > White gradient and set the blending mode to Soft Light.
To get a feeling of old astronomy images, let’s create some circles around the moon. To do that, create a black circle with the Ellipse Tool. Click Layer > Layer Style > Stroke and set the size to 7 pixels. Set Gradient in the fill type and choose a blackto- magenta gradient. Repeat the process using other stroke colours, like orange and blue.
