Note:  When constructing many backgrounds, banners, and buttons with Background Magic for an image archive, the Image Blend must never be more than 70% of a Background Magic tile.  

1.  Let's say for the sake of this tutorial that you want a particular background tile to be used in an archive.  You like the color and texture of the original tile, but  you are concerned about the 70% rule.  That can done within the rules even on tiles that are less flamboyant in nature.

2.  Drag and drop the two tiles pictured below into the Image 1 and Image 2 locations.

3.  The Final Image at this point is too milky.  Let's fix that.  Click on Image 1 to enable it.  Then click Erode, Keep, and Soften, Keep two times each. 

4.  Click on Image 2.  Then click Sharpen, Keep two times.

5.  Slide the Image Blend slider to 68%.   Then click on the Final Image tile and then click Sharpen, Keep one time.  Then move the Brightness slider to 95%, Red to 103%, Green leave at 100%, and Blue 93%.   Those procedures result in the representation below.

6.  Click on the tile below to view how it looks on a web page.  There are slight differences, but the original Background tile and the newly created tile are very similar.
