Without a doubt this is my go-to overlay package!
Use it as smoke, fog, to add some instant atmosphere to all your composites.
Give it a blur to create depth in your images, add to simulate cigarette smoke or add a colur filter for a fabulous dreamy effect. The possibilities are endless!
70 high resolution files for you to keep and use...and trust me you will use this one a lot!
