GPU-accelerated Bokeh Blur, new in PD Pro 8.2
This tutorial is a bit more into Photography, but of course you could do this on a 3D rendered landscape scene as well. Or an industrial design, where you want to bring the attention to something in the scene and blur the rest around or behind it. The idea is to select parts of the image with a gradient selection and apply a sophisticated blur effect that mimics camera iris shapes. The amount and size of blur is affected by the depth of selection. We call it Bokeh Blur - the new and enhanced custom blur in Dogwaffle 8.2, now also with GPU acceleration
8.2 is not out yet, if you order v7.x here at DAZ you get a free upgrade to v8.
