Step one:
Open a new document, make it any size, but it's better to make the width bigger than the height. Mine was 200x100, for example. Go up to "Windows" and choose "Show Channels" if the Channels window is not already open.

Step two:
Click on the "Channels" tab in whatever window it is in. Now, click on the "New Channel" button.

Step three:
Now using the Square Marquee tool, make a rectangular selection in the new channel, leaving room on all sides. Fill the selection with white, then deselect.

Step four:
Now go up to the "Filters" menu and under "Blurs" choose "Gaussian Blur". Enter the amount of between 18 and 22, those worked best for me. Then click "OK".

Step five:
Go up to the "Image" menu and under "Adjust" choose "Levels". (MAC:Apple+L, PC:CTRL+L) Move the level slider on the left towards the middle, now move the right slider next to the first one, until you get the desired shape and size you want. Click "OK".

Step six:
Now, back in the "Channels" window, drag the channel you just made down to the "New Channel" button, this should copy the channel.

Step Seven:
With the new channel selected, hold Apple key (PC:CTRL) and click on the first channel. This should make a selection. Now go up to "Filters" and under "Blurs" choose "Gaussian Blur". Choose a Radius of around 14 pixels. Click "OK".

Step Eight:
Click on the original image. Go up to the "Select" menu and choose "Load Selection". Load the first channel you made as the source.

Step nine:
Go up to the "Filters" menu and under "Render" choose "Lighting Effects". In the lighting effects window, use the settings Intensity - 17, Focus - 31, Matte - 0, Material - 69, Exposure - 0, Ambience - 8, Texture Channel - the second channel you made, make sure White is high is checked and a Height of 50. Now click "OK". Adjust the angle of the light to where you like.

Step Ten:
To add a little effect, add a small circle using the paintbrush and using the smear tool, shape how you like.
