Next time I go out taking pictures of flowers, I'm gonna take me a set of watercolors and a block of paper. Then I can get the background I want. No, it's not my idea. John Shaw talks about doing this behind fish tanks to get nifty, out of focus backgrounds. Though it's faster and easier to do it in Photoshop.
Either way, the image is manipulated. (Now if that's not troll bait, I don't know what is).
The background is a great colour, but this image is really needing a point of focus... it's a shame that the flower is blurred. Yellow and blue are such striking colours together... did you ever try this again?
