Smoky night effect

Step 19

Now duplicate that last layer and run a Gaussian Blur by going to Filter > Render > Gaussian Blur with a value of 4px. This will make our layer look a little softer.

After that, get a large soft eraser brush and just brush away some of the bits at the bottom and top so that it fades off as it approaches the edges.

You may also want to repeat these last couple of steps to add more wisps.

Step 20

Here I've removed the bottom of those wisps and added a few more subtle copies. Also I added some extra type above the main text just to make it look a bit cooler.

Step 21

Next I moved one or two of the wispy layers in front of the text so that it looks like the smoke is trailing over the letters. In particular look at the E in super to see what I mean.

Step 22

Finally, to give it a more eerie feel I added a layer above all the others and with a large brush painted some green on top, then set the layer blending mode to Color to make it so that the image is a blue-green coloring. And we're done! One slick, smoky effect!
