Full Signature

1. Open up a new document which ever size you want. I made mine 321x123 with a white background.

2. Click on the paint bucket tool and select the color black and click on your document once.

3. Make a new layer and click on the brush tool, select a good brush, set the color to white and brush your signature.

4. Pick a nice render and place it on your signature. duplicate your render so now you have 2 of the same, click on the bottom one and go to Filter > Blur > Motion blur

angel: 35
distance: 50

Set the layer to overlay

5. Duplicate your render 2 times, the one which is blurred and place it all over the signature.

6.Get your render which is not blurred and place it on your signature, duplicate it. So now you have 2 renders, select the bottom one and go to Filter > Blur > Motion blur and use these settings:

angel: 90
distance: 10

And now set the opacity to 70%. Set the layer to overlay.

7. Duplicate your render 2 times, the one which is blurred and place it all over the signature.

8. Get your render which is not blurred and go to Filter > Blur > Motion blur and use these settings:

angel: 0
distance: 150

And set the layer to overlay.

9. Get your render which is not blurred and go to Filter > Blur > Motion blur and use these settings:

angel: 0
distance: 70

And place it on the left side of the signature, duplicate it and put this one on the right side of the signature and set the both layers to overlay.

10. Get your render and this time just set the layer to hard light with opacity to 60%, duplicate your render and set the layer to overlay and opacity to 100%.

11. Now all you got to do is, add your text.
