I've also been having a lot of fun with the Blux camera app. If you check out the Hershey's Kiss image and the strawberry image, I was using Blux to capture those. I love that it will allow you to focus on one particular point blurring out the rest of the image. It definitely makes the images more interesting.
That is my prop for Blux! Go check it out!
