Angle the camera right and it can be warm colors or cold colors.

Thanks for your comments. And its those comments that keeps me on my toes. This photo is unretouched and pretty much just out of the camera.

I have shot a few photos of CDs in direct sun but none as spectacular as this. In your opinion, do CDs or DVDs produce the best effect or are they about equal?

Great work.

Cal

They all reflect the prism equally but there are so many different colors for the material inside the plastic part of the disk. The part that gets written to. Ive seen burgundy, green, blue, silver, gold. The color might affect the end result but not by much.

I was thinking that the track density might affect the refraction process.

Yes, Cal.

The dot size is comparable with the wavelengths of the light used to write and read the disks, so we have in effect, a 'diffraction grating', as used (with X-rays) to elucidate crystal structures and molecular structures. The amazing advances in consumer CD/DVD technology depend on ever smaller dots written and read by ever smaller laser beams, of ever more variable wavelength (colour), with ever better error-checking (we hope).

When we view these through our cameras' and our eyes' own small visible window of less than one octave (400-700nm), via an assortment of different ways of creating the digital 'dots', lots of interesting sights are likely to be seen! I hope Bynx has inspired us to look for them.

Very well put Alan. I just know the disk makes pretty colors and I point my camera at the colors and take the picture. Im a simple minded creature.
