First I will show you the tools that we're going to be using, which we will need the Gradient Tool, and the Pen Tool.
Step 1: Selecting and Using Your Gradient
For this instructable I choose a deep purple blue fading to a blue teal.
Start from bottom to top with your Gradient, and as long as you HOLD SHIFT the Gradient will stay straight all the way up the page.
Step 2: Creating a Selection With the Pen Tool
With the Pen Tool, a single click will make a point, but if you click and drag the Pen Tool then creates curves on the points.
Step 3: Creating Your Aura Gradient
When ever in doubt of what you're doing, make a layer for it. It's alot easier to delete a layer and start where it left off, rather delete the whole picture because you didn't make layers.
For the Aura Gradient, I'm picking white which seems to turn out pretty well. You can pick any physcdelic color you want for your gradient, mix and match, have fun with it.
Step 4: Applying Your Aura Effect
Make Selection will be your friend while using the Pen Tool. If you have something sneaky you just can't seem to select, adjust the nodes that you put down from the Pen Tool, and get it 100% right before you Make Selection out of the path.
To make a selection out of a path, make sure the path is first selected, then right click ANYWHERE on your image and select "Make Selection."
To Inverse your selection you've made from your path, goto select, then inverse or Shift + Ctrl + I
Step 5: The Final Outcome
Now you have the skills to do a bit more with the techniques I've shown you. As you can tell, most of this technique lyes in the paths, so play around and make detailed curves to resemble symbols, words, pictures, and more!
