425pm Walk-on ferry to Pender arrive 6:50pm ($12 each)
I recorded most of the conversations we had that day with the intention to publish an interview but it grew to be something else: Gravity wins, Entropy rules
The following is a simple excerpt from that several hour long recording
START OF Al 2.m4a ( Begins @ 7 mins)
Felix: The holograms, they don’t last forever right?
Al: No. Some of them disintegrated predictably over time. It depends. If you have a dichromated emulsion like the green one over there. That’s ammonium dichromate which cannot touch water. If it does — if there’s a little crack in the glass and the water seeps in — it will start to erase progressively, you know. It’ll become a blank plate. And you’ll watch it overtime do that and you can’t stop it.
F: It's not an archival process?
A: No.
F: So archiving these things is important also because these works are always changing over time.
A: I’m gonna have to fire up the laser for you tomorrow. You know because you should take a look at the transmission holograms. Their resolution exceeds that [the reflection]
F: Transmission hologram is a hologram that needs to be lit with a laser from behind?
A: Mhm. the light is transmitted through the hologram. And the photons are refracted. The reflection holograms here are done in such a way that the emulsion acts as a filter — both for colour — and it filters out all the other wavelengths that would contribute to blurring the image. It acts as a complex mirror full of light. The transmission hologram acts like a complex lens.
F: that’s a really good analogy that I didn’t encounter while reading about these things. A mirror vs. a lens.
A: Same laws of refraction and diffraction apply. For mirrors and lenses.
