My first thought on seeing this, and your bicycle shot, was that they were Lensbaby ones but then your comment about blur has me asking, is this a post processing effect, or something in camera?
@gardencat --this two pictures were edited using "lensblur" from Snapseed, it's a free editing apps for iPad.- I do used lensbaby once in a while but not with this images..Thanks v much-glad u like them:)!
