Today, you will be learning to make a signiture like this:
First, get a render of your choice, mainly one with a bit of movement in it though:
Make a new image, and colour it so it is like your render:
Make a new layer and fill that layer with your render:
Put a gaussion blur onto the layer with a setting of 8/8
Do Filters>Noise>Pick and do these settings:
Paste your render on, then do filters>blur>motion blur on the noise>pick layer at an angle that gives the most flow.
Do any resizing, blending, borders and text for the finishing touches.
(the text should be in a corner with a blending colour and nice font.
Extra note:
If you want, you can get out your sparks brush, make a new layer under the render and set it to dodge, go crazy with sparks and lower/raise the opacity to your liking.
Other examples:
And this is my old signiture, and one of my favourites with the good blending :p
