I was actually looking for cool and/or useful actions for Photoshop, when i stumbled upon Mystical Lights by Pro Add-Ons.
The Mystical Lights pack is a pack of 150 different pictures (or ‘overlays”) to make lighting effects in Photoshop. I decided to start by exploring the bokeh effects.
Bokeh is originally the aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens. In later years people have had a more artistic approach to bokeh, using it to create a cool effect in some pictures.
Here’s some examples of adding bokeh to pictures. NB: Some also have some natural bokeh, but you can usually tell what is real and what is added.
