We’ve covered the blurring technique that some of us have adopted on Windows Phone recently. The trick is to find an image you want as your lockscreen and then to blur it using a filter in Photoshop or something similar. The effect is to basically add ‘bokeh’ to the image, allowing you to still see it, but making the text (and notifications) more legible.
We also recently posted Lock Widgets by Jaxbot from the site Windows Phone Hacker. That app added some cool weather and battery info, and when we ran the story, we showed it with a blurred background.
Evidently a light went off in Jaxbot’s head as he’s gone forward to create a freebie app that simply takes whatever image you want and adds “blur” to it. Intensity is based on a slider scale, and users can either save directly to their phone or instantly make it a background.
