This is not a tutorial. It is a Not Tutorial. Confused? Hopefully it will all be clear by the time I’m done. More than once I have come across tutorials on how to use Photoshop to create planetary rings. In fact since this is totally Photoshop specific, it will serve as the inaugural posting to a new topic section devoted to Photoshop. While I have mentioned Adobe Photoshop in several previous postings, I have never gone into sufficient detail to warrant creating a Photoshop category – until now.
Back to planetary rings and Photoshop: there is a widely prescribed method for creating rings which I call the swirly clouds method because it relies on Photoshop’s Twirl Tool. Let me give you a quick run through of how these tutorials proceed. We’re not going to worry about the planet. Our focus is on the ring system and how it gets created.
- Start up Photoshop.
- Create a 1000 by 1000 pixel document.
- Fill the background layer with black.
- Create a new layer named Rings.
- Make the Rings layer the active layer.
- Filter -> Render -> Clouds
- Filter -> Distort -> Twirl using an angle of 999Â°. Repeat two more times.
- Activate the Elliptical Marquee Tool
- Position your cursor at the center of the document and click-Alt-Shift to create a centered perfectly circular selection. Drag to the desired inner boundary for your rings, release, and press the Delete key to remove the inner swirly area.
- Position your cursor at the center of the document and click-Alt-Shift to create a centered perfectly circular selection. Drag to the desired outer boundary for your rings, release, press Shift-Ctrl-I to invert the selection, and press the Delete key to remove the outer swirly area.
- Ctrl-T to activate the Transform tool. Flatten and tilt to create the perspective you want for your planet’s rings.
And that’s all there is to it. Note that following step 10 you could have added noise, color, whatever. Not bad for five minutes work.
But there is a problem, especially if you want your rings to be big. Take a close look at the rings that you have just created and at the rings in the picture below.
The red dots mark points where the rings appear out of nothing and disappear into nothing. These points are a direct result of using Photoshop’s Twirl Tool to create a circular material. Granted they are not very noticeable but they are noticeable and not at all realistic. Real rings just don’t work like that. While there may not be a quicker way to create rings for your planets, there are better ways.
My advice is if you are serious about your planet’s rings and your rings are going to be large and you come across a Photoshop tutorial that expounds the basic twirly ring methodology: ignore it. Having said that, I will point out that the rings used to illustrate this “not” tutorial were made using the swirly rings method.
Note: It has come to my attention that Internet Explorer is unable to display the numbers for the ordered list used to identify the individual steps in the tutorial. Obviously IE is developmentally challenged. Firefox has no difficulty displaying the numbers
