Interference patterns of street lights seen through a tulle curtain. Narrow openings (slits) in the curtain cause the light to be bent and interfere on the camera sensor. The constructive and destructive interference cause high and low intensity bands. Also the white light is resolved into its constituent colors through interference.
From Wikipedia:
Interference is a phenomenon in which two waves superpose to form a resultant wave of greater or lower amplitude. Interference usually refers to the interaction of waves that are correlated or coherent with each other, either because they come from the same source or because they have the same or nearly the same frequency. Interference effects can be observed with all types of waves, for example, light, radio, acoustic, surface water waves or matter waves.
It's cold outside, I'm waiting for some parts to arrive to continue another photo-project but they are delayed due to "weather conditions or natural disaster".
So today was soldering practice day. These are made from 4cm pieces of straightened brass hobby wire and soldered together by a soldering rookie (me). Then dipped in bubble blowing solution to get pretty soap film arrangements and photographed in a 'light tunnel' to get the pretty thin-film interference colours we love in soap film.
Other Info:
-bare SB-80dx just in front of the model aiming to the right, triggered with rf-602.
-model and the flash are in a tube of white cardboard, which reflects nicely on the soap film.
-there are 5 'platonic solids' that you can make friends with. The missing two (dodecahedron and icosahedron) are starting to get complicated. If winter is long enough, I'll give them a try.
-much can be said about the shape the soap film takes inside a wire frame, if the winter is even longer I will have to dig out a few of my old math textbooks.
"M91 è il terzo orso ucciso da Fugatti dall’inizio dell’anno. Anche questa volta ha agito col favore delle tenebre ed immediatamente dopo la sua delibera, per non dare tempo a nessuno di fare ricorso, nemmeno le associazioni abituate a dover lottare contro il tempo.
Ma qui è tutto orchestrato per evitare qualsiasi interferenza. Una vera ossessione malvagia quella di Fugatti per proseguire nella sua campagna di sangue e propaganda.
E il Ministro Pichetto Fratin continua a non fare nulla mentre questa estate ci aveva sorpreso con la frase “uccidere gli orsi non è la soluzione”. Bene Ministro, ci dica se davvero intende fare qualcosa o le sue sono solo chiacchiere."

"M91 is the third bear killed by Fugatti since the beginning of the year. This time too he acted under the cover of darkness and immediately after his resolution, so as not to give anyone time to appeal, not even associations used to having to fight against time.
But here everything is orchestrated to avoid any interference. Fugatti's true evil obsession was to continue his campaign of blood and propaganda.
And Minister Pichetto Fratin continues to do nothing while this summer he surprised us with the phrase "killing bears is not the solution". Well Minister, tell us if you really intend to do something or it's just talk."

Soap film interference colours, Shot using a flat soap film in a wire loop and a LED light source. It turned out the shutter speed was a bit too low in this series.
A stunningly clear October evening on the Jurassic Coast.
For a number of years there were various discussions about ways to commemorate the pioneering work on radar undertaken at Worth Matravers during World War II. Towards the end of the 1990s Tony Viney, a Worth resident and parish councillor, progressed proposals through the Worth Parish Council to erect a radar memorial at St Aldhelm's Head. Tony Viney, himself a local sculptor, also designed the memorial.
The stainless steel memorial is set on a Purbeck stone plinth. It represents two radar dishes which are arranged in such a way that they also form a large fire basket. This reflects both ancient and modern methods to warn of invasion: fires were lit as beacons to warn of the Spanish armada while radar forms the modern equivalent. The tiered stone base is also a good resting place for weary walkers! - and allows them spectacular views of the coastline.
This shot was a 13 Sec exposure at a very ISO, hence the noise, but it goes with the title well!
It was not memory.
It was not presence.
Only a reflection –
the trace of a body
on a wall.
The light was out of time.
Too warm for that suspended world.
A golden intrusion
that lasted less than the shadow.
A presence no longer belonging to what holds it.
A space that lets every trace slip away.
Only a glimmer – and then, nothing.

Interferenza
Non fu memoria.
Non fu presenza.
Solo un riflesso –
la traccia di un corpo
su un muro.
La luce era fuori tempo.
Troppo calda per quel mondo sospeso.
Un’intrusione dorata
che durò meno dell’ombra.
Una presenza che non appartiene più a ciò che la contiene.
Uno spazio che lascia scivolare ogni traccia.
Solo un bagliore, e poi il nulla.

Well… since I don’t have anything new to post… here is another Vertorama from my recent Melkbos sunset shoot.

Although this composition is almost exactly the same as another image that I’ve already posted from this shoot… I like how the ripples from the two small wavelets entering the rock-pool are interfering with each other here… and I really like how the same interference is visible in that tiny curling and breaking wavelet (I’ve included an enlarged crop of that piece in the comments section below).

June 20th 2005 : On a whim I decided to travel down to Wiltshire to Stonehenge to experience the Summer Solstice, taking my trusty Fujifilm FinePix camera with me.
I left London around 10pm and arrived in Wiltshire to find a well organised parking system, although the fields were some distance away from Stonehenge, it did remind me of the film Close Encounters of the Third Kind, overhead lighting, clearer starry skies and darkness outside the bright perimeter.
I did manage a few hours shut eye, rising around 4am to take the long walk to the stones. I would estimate there were in the region of 2000 other folks, maybe more, hippies, new age and curious people too, like me.
As the sun rose there was a genuine feeling of elation, much singing and dancing, chanting and praying going on around me. Honestly an interesting, historical, fascinating and genuinely worthwhile trip to take once in a lifetime! It did help that the English weather blessed us with clear skies, warm enough temperatures and very little wind, with Stonehenge being out on Salisbury plain.
Once the main event finished people filtered away back across the fields, returning to their lives, touched by something unique and locked into memory.
I don’t know if it’s allowed anymore but in 2005 we had free rein over the site, touching and standing on the stones, with very little interference from the organisers. To be honest clearly nobody wanted to cause trouble.
Love to hear your experiences of the Solstice, particularly Stonehenge. Many thanks for taking the time to read this, I hope you can enjoy some of the photos.

The only snowflake in yesterday’s wonderful snowfalls that showed any prominent “thin film interference” colours, and right in the center. View large and read on!
We’ve had some very warm weather lately so the last images I’ve been posting were from my “archives”. Snowflakes that that never got around to editing that were photographed in the past, even though I try to keep the series as current as possible. They’d never been previously seen, but they weren’t necessarily “fresh”. I have over now over 800 snowflakes that I have not edited. If global warming sets in, fear not – this series, at least, can continue. :)
Yesterday, we got our first snowfall of the year that gave large elaborate crystals mixed in with small snowflakes with unique characters. I shot plenty of both and I’ll be sharing them over the coming days, but colourful crystals always get my attention first. The center of this snowflake is like a rainbow in the snow, so a good chunk of time today was spent focus stacking and editing this snowflake to showcase its beauty from tip to tip.
“Thin film interference” plays out when a snowflake has two layers of ice that are very thin, usually created by a bubble or cavity forming in the ice. A full primer can be found here (skycrystals.ca/img/optical-interference-pages.jpg ) but in this case it’s because the snowflake split itself in two. The very center reveals solid ice, but when things get lighter it’s because a bubble has formed based on the “branching instability”, the same physics that causes branches to from the corners also causes the center of facets to grow slower. As the edges of the facet expand more, the center is left behind, and two new layers of ice are formed. If the thickness is just right, light reflecting off of different layers of ice can interfere with eachother out of sync, creating the colours you see.
As the thickness of the ice changes, so too does the colour we see. This brings up a curious question: why do the colours deviate where each branch begins? Why does the pattern change in these areas?
The pattern changes because the thickness of the ice changes; a logical deduction. This is the “how”, but what of the “why”? It’s the first I’ve seen thin film interference present itself this way, but it stands to reason that the corners of the plates growing outward were also growing thicker. This is how “ribs” are formed encircling the center of a snowflake, which causes many fun features including inward crystal growth – if you’ve been following along with previous posts you’ll nod, if you haven’t here’s some clues: skycrystals.ca/img/circles-in-the-snow.jpg
If conditions were subtle enough to cause the corners to get thicker but not the full width of the facet, you’d see something like this. It’s undetectable any other way that with the colours from the optical interference. If you need proof that corners can grow faster vertically than other parts of a snowflake, I’m happy to provide that to you as well: www.flickr.com/photos/donkom/16781523325/
There are a ton of mysteries in a single snowflake. All of these mysteries can be explained, even if I don’t have the ability to do so. The more challenging the explanation, the more fascinated I am with the winter gem I’ve discovered. For more snowflake science musings and all the photographic techniques required to make images like this, you’ll was to hold a copy of Sky Crystals in your hands: www.skycrystals.ca/book/ - it’s worth the read, and with the website in Canadian Dollars… anyone in the US can get the book for a steal right now!

To Wout: Have a great trip back to Holland my friend, it was great knowing you in the past year, and your photos gave me a lot of inspiration and motivation when I first started taking photos of my own. Hope to see you soon in the near future! :-D
