Our idea for today is to create an intreresting wallpaper or illustration, so let's get started.

Start by creating a new file (File>New) that must have 1024x768 px and 72 dpi.



Using next the Pen Tool (P), it’s possible to represent on the file the land’s surface of black color, which shape can be corrected with the Convert Point Tool.



Find in Internet now a picture, having represented on it the Earth planet, cut it out and place it exactly the same way it is shown next picture. The layer must be placed lower than the layer containing the surface of black color.



Apply on this layer the next parameters, making a mouse click on the layer on the layers’ panel.
Blending Options>Inner Glow

 



Find in Internet also the picture of the sky and insert it on our picture, placing its layer lower than the black surface’s layer.



Make a mouse’s click on the lowest part of the layers’ panel on Add a Mask option. After that we’ll select the Eraser Tool (E) and the Opacity of 10% to erase the area above the planet.



Create a new layer and make a mouse’s click on the lowest part of the layers’ panel on the next option: Create new fill or adjustment layer>Curves (the layer should be placed lower than again the black surface’s layer).

 



Press Alt button and make a mouse’s click between the layers of Curves effect and the sky’s layer for the effect to be applied on the sky’s layer.

 



Find in Internet now another picture of the sky and insert it on our basic picture. The new layer should be placed also lower than the black surface’s layer.
