The first photo was adjusted just a bit and then I started playing with filters. The middle photo made use of one of my favorite filters, poster edges, which defines all of the edges in a photo.
For the third photo I played with some blur effects which brought out the center flowers which I thought were the focal point. Does it make you feel a little dizzy?
It's just fun to experiment and play. Sometimes you say "wow" at the result and other times you say "eewww" but you'll never know what you'll end up with.
