In this tutorial I want to show you how to create a Space Light.

Step 1.
Create a new 450X350 pixels document with a black background. Apply Filter > Render > Lens Flare with the following settings: Brightness -> 100%, Lens Type -> 105 mm Prime in the each corner of the picture. Apply Filter > Render > Lens Flare with the following settings: Brightness -> 100%, Lens Type -> Movie Prime twice in the center of picture.

Step 2.
Apply Filter > Artistic > Film Grain with the following settings: Grain -> 0, Highlight Area -> 17, Intensity -> 5.

Duplicate this layer. Now choose the top layer and change the Blending Mode to "Linear Burn". Apply Filter > Blur > Radial Blur with the following settings: Amount -> 100%, Blur Method -> Zoom, Quality -> Good. And merge down these layers.
