| Here at DPC, I've seen refractions and reflections done in water drops. I am more interested in reflections because it is harder. Are there any tutorials any of you are aware of. I've tried and it is a very hard thing to do. |

| John posted a "how'd they do that" for his "Liberty and Justice" photo. Is that the type of photo you're referring to? Check it out here. |

Could you point out some of the water drop reflection photos? You've got me curious now. I did a quick search on the web and find there is a lot on the refraction aspect of water drops but very little on reflection. Most of the "water drop reflection" hits were for photoshop and other image processing software so they were digital effects rather than real.
You might try a simple experiment. Take a dark object and place a drop of water on it. From what I've read any sufficiently smooth surface is capable of reflecting light and a drop of water is as smooth as you should get. With the dark surface behind the drop of water you should have the best starting point contrast wise for detecting a reflection in the drop. You can then try different colors and surfaces to enhance the contrast between the background and the reflection in the drop.
If you get something, even in the first few trys, post it so we can see it too.

Actually, that picture is a refraction, not a reflection. Excellent picture, but not what I'm asking about. |

It's a combination of a reflection and a refraction...

I'm not sure I understand where the reflection part is... Do I have a flawed definition of 'reflection' (an image of an object bouncing off another object) or am I missing the bounce? |

I agree with you. I just went to www.m-w.com (Webster's online dictionary) and the picture John did is only a refraction, not a reflection. I am very much awed by John's photo and it is one of my favorites of all time, but that doesn't change what it is.

There are most definitly reflections on the water drops in "Liberty and Justice". They're very subtle, but during that challenge I tried very hard to work out if that photo could have been created in 3d software, and decided that it would take much more work than anyone would ever want to do in order to either get those reflections from raytracing or environment mapping.

That's like saying a rainbow isn't an example of a reflection, no?
