Create a Rainbow in Photoshop


In this tutorial I am going to demonstrate on how to create a rainbow in photoshop using some of its basic tools. These basic tools are the rectangular marquee, gradient fill and polar coordinates filter. It may look difficult to create but actually it is fun and simple. Just follow the steps below and surely you’ll be able to create a rainbow in photoshop in just a minute.

1. Start with a new document. Be sure that the dimensions are square. Make the size a few pixels larger than the width you want for the finished rainbow. Here, I use 400x400 pixels.
2. Make a new layer.
3. Make a rectangular selection with the use of the rectangular marquee for about twice as tall as you want your rainbow width to be. Make this selection just a few pixels away from the bottom edge of the document, but not touching the bottom edge (see image below).

4. Select the gradient tool, and choose the Spectrum gradient.
5. Hold the Shift key down, click and drag from the bottom edge of the selection marquee to the top edge.

6. Press Ctrl+D to Deselect the selection
7. Go to Filter > Distort > Polar Coordinates. Make sure "Rectangular to Polar" is selected. Click the - (minus) button in the filter dialog if you want to preview the effect.
8. Click OK and your document should look like the example here.

9. Optional: Add a slight Gaussian blur to the rainbow to soften the edges. By doing this Go to Filter > Blur > Gaussian Blur and Click OK. 10. Select the bottom half of the rainbow and delete.

You have now created a rainbow in its own layer which you can copy to another document or save for future use.

CS3
Photoshop CS3 is now at version 10 of this phenomenally successful program (well twelth actually, if you count versions 2.5 and 5.5). And it all started almost twenty years ago in late 1987, when Thomas Knoll with his brother John, created the first prototype version of Photoshop. Photoshop CS3 has come on a long way since then, so much so that even in a big book like this there is only enough space to cover the features that are of specific interest to photographers....
