OnOne Software has recently released version 6.1 of Perfect Photo Suite, which combines its most-used tools into one package. Among my favorites is FocalPoint, which allows you to select an area of focus in your image and selectively blur the rest, optionally adding a vignette. I used this to great advantage in post-processing my portraits of Tanzanian children during my visit there for the nonprofit group Africa Bridge. I did that editing in Photoshop.
Today, Perfect Photo Suite can be accessed from within Lightroom or Aperture, and OnOne has implemented a technology called Perfect Layers to allow you to combine different effects without going into Photoshop. This takes a considerable amount of memory to pull off -- my Windows 7 64-bit system choked on this and other plug-ins when I had only 4 mg of system memory, but since upgrading to 8 mb, Perfect Photo Suite sings.
The above image of the Seattle Space Needle uses what is called the Orton Effect. named after Michael Orton who developed the technique of sandwiching two images, one in focus the other out of focus. I've written a Photoshop action, available on my Photoshop actions website, that accomplishes this, but Perfect Photo Suite allows you to create this effect through Lightroom.
There's lots more in the suite, including Perfect Resize and the latest version of Photo Frame. It's a versatile and straightforward toolkit.
