I found this wonderful photo album by Hans Van Rafelghem. Take a look at the garden plants. I just about sneezed when I saw his photo of the dandelion. I mean, to have the ability to make even the weeds look good, now that is great photography.
He also has a a nice photo of calendula. And the Centaurea montana is one of my favorites. The color is out of this world.
I am trying to learn how to do photography like this.
