Easily, one of my favorite Flickr photographers has got to be Irene L (aka i.anton). Her photos are best described as poetic - with careful retouching she takes simple photographs and turns them into little pieces of art. There's almost a magical quality to her photos. The way she manipulates light and captures color enhances the viewer experience, it makes the simple...stunning.
These five photos belong to her out of focus light blobs set but when you have some time, make sure to check out all of her amazing work here.
