Wanted to do these for ages and have tried before with no luck, however think I have nailed it this time.
First in honor Paul's fantastic wording :-
However this was not the effect I was after, this was shot into a shallow (1 inch) Pyrex dish and this is the water drop bouncing back, what I wanted was the classic crown :-
Shutter 200 sec fastest standard sync, the motion is stopped by flash.
Aperture f5.6 (to give some DOF over crown and variations in impact point.
Lens 100mm Macro, manual focus.
Camera on tripod, motor drive and cable release.
One flash camera left, another one camera right on eTTL metering. Controlled by STE-2 controller on camera. Red gel on left strobe and blue gel on right and color bias controlled via ratio function on controller.
A bit (but not much) of PP saturation and sharpen tweak.
Overall I shot 633 images, got 20 okay results and these are the best.
If your interested I've posted some more shots as well as some set up shots on my own blog.

Following up on a comment by Paul / Nick on distortion I wanted to add some photos but can't in the comments so hence fresh post.
Both pincushion and barrel distortion are caused by non liner magnification across the image. They are in the same effect but opposite.
Barrel is when the edge of the lens is weaker than the middle. This is the most common and normally seen on wide angle lenses. You often see the tops tall buildings leaning inwards and not vertical with the frame edge, this is barrel distortion.
Pincushion (all one word) is when the edge of the lens is stronger than the middle. this is normally from low end telephoto lenses and not as common these days.
What can you do about it ?
- Keep the image plane (film or sensor) parallel with the subject, however this is difficult if shooting "up" at a building. This evens the effect out rather than correct the problem is though. Paul did a good job this way in Doha.
- Tilt and shift lens, VERY expensive but these you can tilt the lens off the parallel so takes care of the above issue. Both effect are lesser with expensive lenses but not gone.
- Photoshop. You can correct both effect in photoshop but the part of the image is cropped off.
(Images are of Google, same image in multiple sites but think it's thanks to Wiki originally.)
p.s. Sorry for the nerdy post !

Tried to get some symmetry here, with the gate lights and their reflections in the puddle. The hosepipe also counts as 'water', partly because I liked the splash of contrasting colour and also because I wasn't about to clone it out. That treatment was reserved for the obtrusive red 'No Parking' sign on the wall opposite the gate.
Nikkor 18-200 @ 112mm
Having retrieved my camera from the car, I was heading back into the office with intent to take a particular shot that I had in mind. Whilst that shot never happened, I saw the minaret reflected in a puddle and liked the texture. I simply inverted the image.
Nikkor 18-200 @ 170mm
Dubai Boat Show offered plenty of opportunities for 'Water' as the subject matter. I tweaked up the red gelcoat using a mask so that the red would 'pop' without the water developing a reddish colour cast.
Nikkor 18-200 @ 29mm
More Boat Show. It got dark, and I knew from experience that tripods on floating boats and pontoons is a recipe for camera shake, even if some oaf doesn't kick it all into the oggin. So I used the trick of setting the film speed (on a DSLR - Hahaha!) to Auto so that I could hand-hold the camera. There's a little bit of cropping and cloning to get rid of distracting bright lights. Look at the symmetry of the boat in the water, and also note the metalwork at the waterline that just hints of Poseidon's trident.
Nikkor 18-200 @ 38mm
Again, hand-held in the dark (don't you just love vibration-reduction lenses?) at the Boat Show. The whole frame is of a sexily lit speedboat, but I thought the coloured reflections were more interesting. The graininess is caused by the high 'film speed' and also the cropping.
I should also note that I wanted to freeze the ripples in the water, so long shutter speeds that would allow blurring were something I actively sought to avoid.

Better late than never, so here is my attempt at last months "Miniature / Small world". Following Paul's non photoshop with water I thought I'd be brave and bare all! These are all straight out of camera, not even a watermark !

Manual Focus (measured)
Tripod (yes inside the box)
Off camera flash top right.
16mm, 1/5sec, F5.6, Av
Off camera flash top center, to help texture.
50mm, f5.6, 2/5sec, Av
Total -2/3 ev.
Flash low left.
50mm, f5.6, 2/5sec, Av
Total -1/3 ev.
Flash high right -1ev.
100mm Macro, f2.8, 2.5 sec, Av
Flash top right

Flash low right.
As always, comments, abuse and questions welcome.

Scanned from a negative, so no EXIF data
Spring is here. This springtime shot of a Canada goose and her brood of goslings was taken in May 2001. Say, "Aaah." Located at Crofton Pumping Station, near the summit pound of the Kennet and Avon canal, I remember being distinctly cold and damp. The overcast skies are why the water is that foreboding gumetal grey. There was no heating in the boat, nor running water.

At the time, 2001, this was called the Doha Marriott Gulf Hotel. It's now simply the Marriott. I was on the roof of one building, and happened to spot the reflection of the rig support vessels moored nearby.
