Mosaic Header

This is the effect that can be seen on pixel2life.com (we had permission to write this tutorial)

1. Open your header for your website, in this tutorial we just used a background.

2. Click layer > New > layer from background - which basically makes the background unlocked

3. Next, hit image > canvas size, and make your height twice as high as it was.

4. grab the polygonal maqruee tool, and make a triangular selection (hold shift whilst doing the diagnol bit, as it gives you an exact 45* angle)

5. hit delete, to get rid of the selection

6. hold CTRL and press D to deselect, and with the polygonal marquee tool, make a bigger selection (see image) quite a way up the side and the bottom.

7. click selection > feather - and feather it about... 30px

8. Next, Filter > pixelate > mosaic - and give it a cell size of 5 - hit OK

9. click Filter > mosaic, another 2 times

10. Filter > sharpen

11. set your background colour to a colour, that you would have if the image was blank. for our example, we might choose light blue, or white.

12. click image > canvas size - and make the height a half of waht it now is.

13. Layer > new > background from layer (which should give you that background colour)

14. File > save
