I've posted some water drop photos in the past, but I really think these take the cake. 

And one more - as simple as it gets:

The setup is a great deal simpler than you might think:

-Tall glass of water
-Some measuring spoons for making the water drops - various sizes for smaller/larger drops
-Studio backdrop (for the neutral background) - could even be done in a softbox
-Two lights on either side of the glass to light it up
-Cable release

For these, I used a 70-200mm f/2.8 lens, all the way in at 200mm to get that close. The tricky part with shooting that close with f/2.8 is the setup - finding your focal point can be a real challenge. Take your time, be patient, and don't give up. You can't see it in the camera because you are too busy making water drops - trial and error go a long way.

So here's the exciting conclusion.

I think that flowers are all fine and dandy - but a little water goes a long way. I took a few shots of the rose without water drops, and it didn't tell the same story. Call me crazy, I just like it this way a little more.

This next one isn't really 'macro' per se, but it was done in the same environment.

This one had a great deal of post-processing. Not to change the shot, but to get the desired lighting I couldn't seem to get right during the shoot. Obviously, I put s pretty large 's-curve' on it, followed by a few curves adjustments to get the color of the flower a uniform hue. Looks good now.

Lastly, a different frame.

This will be a two-part post focusing on macro photography - specifically, it will discuss the importance of how creative solutions triumph over expensive lighting equipment any day of the week. Well, I guess creative solutions plus expensive lighting is better, but who's arguing?

Both shots for this post were done with a small bowl, water, a spoon for water drops, a single flash, and some post-processing to top it off. Oh, and a boat-load of trial and error. 

No, the images don't come out of the camera looking like that - I didn't add the water drop, but I did crop it and add some color.

Expensive solution: super-expensive macro lens and super-expensive lighting.

Creative (Cheap) solution: Lots of cropping and a single flash.

Call me crazy, but I like the second option a little better.
