It was cold last night and  when we awoke the world out our windows was covered in frost. Eventually that frost melted. And the resultant drops on the covers of our patio furniture looked like this.

All sparkly.

It was Patty who first noticed them. And knowing my interested in such things, quickly alerted me. It was no doubt the sparkling colors which caught her attention. Dew drop colors, frustratingly difficult, for me anyway, to take good pictures of. But I continue to try. And got a few that were "blog worthy" as I like to call them.

The colors arise like those in a prism or rainbow, the differing wavelengths, corresponding to different colors, refract at different angles. Physics in a dew drop. I noticed some other interesting optical effects as well.

Diffraction Grating. The shot above was from inside the house, the others, all outside on the deck. And when shooting from inside it was through a screen, which forms a two way diffraction grating, (up-down, left-right), resulting in rainbow crosses (click any image to bigafy it).

Dew Bow? I'm not sure if this is an actual bow, or if it is an artifact of the curvature of the cover. Interesting nevertheless (at least to me).

Lens. I'm not sure what caused the initial drop in the center to consume those around it and grow larger, perhaps I pressed there when moving about the chair looking for shots.


I'm still trying for that 'perfect' sparkle shot, either of dew drops or ice crystals. Good thing I now longer need to use film!

Keep looking down!
