Here is a photo that has not been manipulated in any way. It is amazing how the flower seems to float in midair. (via)
The photographer explains how he pulled off this image.
"To give an answer on the question how I did it. Simple sunlight, white paper, a glass vase, a tiny flower and a little observation and improvisation. The sun shines through the vase adding lightbeams on the paper and that gives an extra dimension on the mini flower. That`s all. I hope my English is good enough to make it understandable. :)"
