Topaz Lens Effects
Shallow depth of field effects are tough to imitate with software, but Lens Effects lets you do just that. You need to create a depth of field mask tailored to your composition in order to accurately apply a simulated bokeh blur, but it’s a tricky process to master and the dated interface doesn’t help.
Lens Effects reproduces other optical effects too, such as tilt-shift lens blurs, fisheye distortions and toy camera styles. However, you’ll find more comprehensive versions of these in other plug-ins, and while Lens Effects has a few unique features, they aren’t enough to make it an essential app.
