In this tutorial we will make the Sun rises in the dark, nothing is impossible!

If you use the original image, you should resize it to 600 pixels width by going to Image > Image Size and type 600 in the first textbox
Step 2: Press D, X to reset your foreground and background colors. Create a new layer and fill it with black by pressing Ctrl-Backspace. In fact, you can fill it with any color you like because we just need a solid layer to do the next step. Your Layers tab now looks like this:

Step 3: Go to Filter > Noise > Add Noise and use these settings:

Step 4: We should reduce the opacity of this layer to see our Background layer, adjust the slide bar under the Opacity property in the Layers tab a bit

Step 5: Go to Filter > Blur > Radial Blur, and use these settings:

The center of these "beams" should lie at the horizon so if you don't blur it right, just undo and repeat this step again. Press Ctrl-F twice to make our beams smoother

Step 6: Change the Blend Mode of the current layer to Screen

After this step we have:

Step 7: Set the Opacity of the current layer to 100% again, we don't need to make it opaque any more. Now we will make the Sun ^_^ by going to Filter > Render > Lens Flare, adjust its settings to place the Sun on the horizon

If you do it right, our image will look like this:

Step 8: Use the Eraser Tool (E) with a soft brush to erase the beams lie on the land

Step 9: To make the remaining beams look more real, we should add a vector mask to it, so click on the Add vector mask icon

Step 10: Use the Gradient Tool (G) with Foreground to Background (white to black) and Radial Gradient options

Hold down your mouse at the Sun and drag outward like this

Now our sunlight looks more real. If you want it brighter, simply press Ctrl-J to duplicate the current layer.
You can use the Brush Tool (B) and pick a nice star shape to decorate your photo. Here is the final result:

You can also apply a vector mask to these stars to make them look more real, have fun with it!
