Photoshop Effects - Circles

You usually produce circles with a vectorial drawing program and export them to the PhotoShop. But, this program can also produce its proper circles or ellipses if you prefer. In the File menu: file>New, 1x1 cm. To visualize your file better, go to the View menu: View>Zoom In and apply it as necessary.

With the aid of the rulers and the strings divide the file into many parts as you wish and give a color to each part like the example bellow. After the bands had been made I applied a filter Gaussian Blur with Radius 1; just to complicate; which caused a gradient effect.

Now, in the Select menu: Select>All. In the Edit menu: Edit>Copy.

Create a new RGB file. File>New, 10X3 cam. It doesn't matter the color of the background. In the menu It edits: Edit>Define Pattern. Edit>Fill, use Pattern, opacity 100%, Normal mode and click on Ok.

Now, in the Select menu: Select>Select All. In the Filter menu: Filter>Distort>Polar Coordinates... mark from Rectangular to Polar. Your effect is ready.

Now, in the Select menu: Select>Select All. In the Filter menu: Filter>Distort>Polar Coordinates... mark from Rectangular to Polar. Your effect is ready.

Repeat this effect using two colors and without the Gaussian Blur effect in a square, and you will have perfect circles.
