Here's an idea I tied for a Macro theme my local Phot club had.
The pic is of 2 roses, one pink/white the other orange/red in a vase. Between the vase and the camera is a fly screen that I've sprayed water onto and then focused on the drops that formed.
You can sort of see the flowers in the drops, some of them in full resolution are quite interesting to really zoom in on and cruise around looking at the different images in each drop.
At a guess from memory, the front of the lens was about 10 or 12 cm from the screen and the roses about 20 cm behind that.
This first one was shot indoors with a spotlight on a bench off to the right and behind me and a spotlight on the floor shining up onto the roses.
This 2nd one was shot outside in natural light.
Pentax K100D and Sigma 28-80 Asperical that has a Macro setting at 80mm.
