# Lippmann video plannig
###### tags: `lippmann` `notes`

### General topics

Ideas I (Michalina) don't think fit in the video
 - ~~digital twin of artwork: origin of project, making electronic facsimile~~
 - ~~Analysis lead to a fundamental understanding of this mode of photography: some equations here ;)~~
 - ~~Idea of standing wave for single color: graphic~~
 - ~~General case: just show it is complicated!~~
 - ~~Forward and inverse transform: a few equations~~
 - ~~Spectral recovery: show block diagram, and the fact it is not exact, but can be corrected~~
 - ~~Was the sky s bluer….~~

History
 - Unique early color photography: we came across a unique set of early photographs at the Elysée
 - Show images and movie: relighting etc Alves at EPFL
 - Lippmann and Nobel prize: we discover it is one of the first color photography methods, and it earned the inventor the Nobel Prize in physics
 - Color photography is usually based on very few “ color” channels
 - RGB: show a Bayer pattern or the like 
 - Interference photography, unique method: it is the only known photography method using interference 
 - Interference and standing waves: some images of standing waves (or just of waves on a pond creating patterns: stock photo, or from Gilles thesis!)
 - Lippmann photo is the earliest example of multispectral imaging: it was 100 years before its time!

Analysis
 - Historical and current photos (Lippmann, Alves, Gilles)
 - Examples with PSI three dimensional cut 
 - shift depending on the material 

Now
 - Interference methods are widespread in physics, eg Michelson, Ligo
 - Multispectral and hyperspectral imaging: show an earth observation image of hypersectral photography 
 - some of the similarities with holograms, which could also be tied
 - EPFL has a successful history with holograms for security --- Morphotonix
 - one of the potential applications of lippmann technology is the production of hard-to-falsify objects.


### Questions for the interview style video
 - How did you find out about Lippmann Photography? 
 - How is it different from standard photograpy? 
 - Who is this Lippmann anyway? 
 - Why Lippmann Photography is not popular now?
 - Why wasn't it well undertstood? 
 - What did you find when you investigated it?
 - How the process works? 
 - What is the future Lippmann photography?

### (Visual) explanation how Lippmann Photography works
 - Waves on the water and interference
 - Standing wave in a glass of water
 - Interference leaving fringes video
 - Sliver grains PSI video
 - Reflection from fringes: soap bubbles, oil on the puddle, holographic chocolate 
 - Show images of a Lippmann plate (at different tilt?)
