I tried my best with this tut. 1. I always start with size 350x100 pixels and white background. 2. Press D to restart your foreground and background color to black and white 3. Go to Filter > Render > Clouds 4. Then go to Filter > Render > Different Clouds 5. Go to brushes and pick brushes number 39 then brush it a bit not too much 6. Go to Filter > Distort > Ocean Ripple, then set 15 in Ripple Size. 7. Go to Image > Adjustments > Hue/Saturation and click on colorize and choose any color what you want (in Hue) then use saturation and change it in 46. Go change Lightness in -18 8. Then go to Sharpen > Sharpen Edges 2 times. 9. Your image should look like this...(your may be different in color) 10. Your finished but you can add text/render if you want Your done with signature background, it can be in any size. Hope ya like it. ^_^
