If video isn’t your thing here are some very brief descriptions of various alternative. I start with a few “free” programs and apps you may already have.
Google+ PhotoI firstly played around in the edit tools within Google+ Photo, since The Patch is a Google+ community and everyone will have access to these tools. The Centre Focus panel does provide nice blur panel & control, which seems to add a radial Gaussian blur and the edge brightness slider works like a conventional vignette allowing you to darken or lighten the edges at the same time. Its really simple to use, once you find it.
For those lucky enough to have new android phones and have recently updated the default Google Camera app (and have gotten pass the PhotoSphere feature) there is a similar feature called lens blur that can be adjusted on your photo on your phone.
PicasaPicasa is Google’s desktop photo manager, which has become Google+ Photos on the web application component. But many of the Snapseed features that have been added into Google+ Photos have not been migrated back to upgrade Picasa itself. The Desktop version does have a very similar filter called soft focus, again using a circular inner zone and allowing control on size of this shape and the amount of focus
Picasa also has an interesting Focal B&W filter. What it does is maintain the colour inside a circular shape and destaturate anything outside that to black and white. There are only two controls the circle size (I've moved it fully to the right) and the sharpness (which is like feathering) and I’ve moved that fully to the left. The shadow lines are still sharp but the desaturation has tamed them.
