Weekend Cat Blogging and Photo Hunt: Digital

The theme of this week’s Photo Hunt is digital. Rather than simply use a digital photo – which could be any photo ever taken of Luna – I chose a couple of images that demonstrate the unique opportunities of the medium. A digital photo is really just a stream of numbers, not unlike digital audio, and can be processed in countless ways using digital signal processing or applying other mathematical functions.

For a piece I originally did in 2007, I took one of Luna’s adoption photos from Santa Cruz County Animal Services and applied an algorithm that overlaid these colored bands, as shown above.  The color bands were generated using a set of hastily chosen trigonometric and hyperbolic functions applied to the timeline of the animation sequence.  These photos are stills from the full animation.

I did these using image and video extensions to Open Sound World – one nice feature of that work was that I could use the same functions for both audio and video, and “see” what a particular audio-processing algorithm looked like when applied to an image.   And I would probably use the Processing environment for future visual work, perhaps in conjunction with OSW.


Weekend Cat Blogging #309 and Carnival of the Cats are both being hosted by Billy SweetFeets this weekend. Perhaps Luna’s animation could be part of one of the dance videos they often feature.

Photo Hunt #264 is hosted by tnchick. This week’s theme is digital.

And the Friday Ark is at the modulator.

A special note this week. Our friend Judi at Judi’s Mind over Matter (home of Jules and Vincent) has information on how to help animals affected the storms and tornadoes in the southeast US. They live in Alabama, not far from the place that was hit hardest by the tornadoes. We’re glad they’re safe, and able to provide this information for those who would like to help.
