My latest photography toy isn’t a new lens. It’s a Mac app that works like a lens, but in post production, rather than live when taking the photograph. The cleverly named Focus app does what your camera sometimes makes it difficult to do. Add depth to a photo by changing the focus.
Drop a photo onto Focus. Tools let you crop or skew the photo, even change the aspect ratio. Then, apply a focus preset to a section of the image.
In this way, Focus works like cameras of old. Focus in the center, out of focus depth of field elsewhere.
The LiveBLUR function lets you preview the focus while you watch.
Focus has a built-in ability to use facial recognition to find the face in a photo and provide automatic focus in one preset.
Considering the price tag, Focus is nicely done, and gives you an option to apply focus (or, out of focus depth of field blurs) to a photo on your Mac, and not have to worry about anything except point and shoot.
Caveats? A few. There’s no try-before-you-buy option. A built-in image viewer of iPhoto photos would be a big time saver. Ditto for more than basic grid support and images beyond standard .jpg.
