There are two actions I’ll provide below that include one called Rays and another, Straight Rays.
Rays will let you create sun rays on any image. From a window, through some trees, whatever works to add interest to your images.
Straight Rays will work better for studio backgrounds where something solid just doesn’t look as interesting.
The video will show you full examples of both. As always, feel free to ask questions or send me some of your results. I’m always interested in seeing what you do with what you’ve learned.
