Pretty unique, would be fun to mess around with but might not translate well for photography.

It only works on the iPhone because the lens is so small, on a larger lens a droplet will just cause a small blurry spot.

Great German photographer Peter Keetman did use glycerine decades ago:

A few years ago I saw some wonderful water droplet photography on the secret Craigslist Photo Forum. These were made using macro lenses to photograph scenes in water droplets found on leaves, etc., in nature. I remember one in particular of a large leaf covered with water droplets all reflecting a bridge or some architecture. I'd suggest searching for "water droplet" on Flikr...

All these were taken a while back using my Pentax K10, the first two with a Vivitar / Komine 28 / 2.8 Close Focus and the third one with a Pentax 50 / 1.7. The focus is on the water drops that are showing the background in sharp focus.

Nice pictures mentioned and shown in the last posts, however the point of the original post is totally different: a drop of water as lens, placed on the iPhone lens. In some way, exactly the opposite Smile

I have seen also dew drops on spider web each with pretty girl inside. Smile Photographer focused on images formed by droplets. Here each droplet is used as lens just as on iPhone.

Liquid lenses could very well be the future for iPhone lenses - they are cheap, they have quick AF and they have no moving parts :

Water used as a lens material is not a new concept. I remember that some British scientists made, decades ago, some very cheap water lenses for glasses with adjustable diopter power intended to be used, for free, in the most poor regions of the world.

Ey, You guys don't need water, go back to the good old glass lenses, of course home made:

Very interesting video, i wonder how the liquid would perform for quality/resolution?

I thought of these as well, saw a program about the first microscopes made from a glass drop years ago
