This is the effect I made that we will be recreating.
Lets go!
Step 1:
Open a new file (with the size of your picture). Now go to Filter→Render→Cloud. Then go to Filter→Render→Difference Clouds. Repeat Difference Clouds around 30 times (Ctrl + F is a shortcut for the last used Filter) until you get something like this:
Step 2:
Now go to Filter→Brush Strokes→Angled Strokes. The settings I used:
Direction Balance: 50
Stroke Length: 15
Sharpness: 3
Go crazy with the settings, I got this:
Step 3:
Now paste it on the layer above the picture, change the Blending Mode to what you like, I chose Color Dodge.
The problem with these kind of effects is that it's random. You can't decide where the lighting comes from. Thats also why you should press Difference Clouds until you are happy with it.
