460 Islamic design 6: Photoshopping the pattern

- In this movie, I'll show you how to…turn our stained glass window…into a seamlessly repeating tile pattern…and give it the appearance of being unevenly lit as well…here inside Photoshop.…And technically, this is something you can…pull off inside of Illustrator.…I just like the experience inside Photoshop better.…So I'll go ahead and switch over to Illustrator.…And the first thing we need to do…is figure out how big…of a document we need…in order to create…a seamlessly repeating tile pattern.…And we can do that with Smart Guides turned on.…

So go to the View menu…and make sure Smart Guides are active.…And then, go ahead and select the rectangle tool.…And apparently I'm on a bad layer here.…So I'll go ahead and select the expanded layer…here inside the Layers panel.…And then I'll drag from the top left corner…of this top left star…all the way down to the top left corner…of the bottom right star.…And notice if I get this in exactly the right location…I can see a head's up display…that's telling me the width value is 422.5 points…
