The freezing and melting of water, as seen with birefringnce and time-lapse photography.
To date, I’ve been content to set water out overnight and examine nature’s icy creations in the morning. A late February warm spell made this proceedure impossible, with unseasonably warm overnight temperatures that turned my liquid water into puddles of slightly colder water. Nice, I guess, but not what I was after for a photographic subject.
Early March featured a nice cold snap and I returned to laying out sheets glass covered in water in the evening. After almost 2 weeks of an early onset spring induced ice-photography hiatus, impatience had set in and I couldn’t wait until morning. Bedtime on hold, I started neurotically checking the state of my ice-to-be every few minutes to see what was happening.
If the crazy colour palette in the header image looks familiar, you’ve either been looking at my past posts dealing with the birefringence of ice, or you remember playing with soap bubbles as a kid (of any age). Or maybe you played with oil slicks, they’re trippy too.
There’s a fancy physics reason for this, with soap film, oil slicks, and these ice photos, the colours are the result of light waves ‘destructively or constructively interfering’ in fun ways to get a spectrum ranging from black, to white, to a tobacco colour, through a classy mauve, over a deep sky blue then a warm yellow, past a pretty pink, then a lighter tasteful blue, finally more or less alternating between neon greens and pinks, becoming duller and duller with each cycle.
Or how to manipulate ice thickness for coloursplosions….
After my initial foray into the Birefringence of River Ice early in 2016, it was fairly clear that the thicker parts of the ice end up…clear, and it’s the thinner parts that liven up between crossed polarizers.
Nature does a fine job of making thin ice on river edges or the tops of puddles with endless interesting shapes to explore, but why not ‘make’ some thin ice and see what happens?
As a bonus, being able to make some thin ice at home means you can photograph it in your pajamas and no trudging off in the cold to a river or a puddle in search of a suitable piece of frozen water. Laziness for the win!
I don’t mind our cold Ontario winters, in fact, I try pretty hard not to complain about freezing my buns off. This gives me the right to complain bitterly about the absurd heat and humidity we’ve had the past few summers – I can always add more layers of clothing to fight off -30°C, but I can only remove so many layers to combat +30°C before I start getting arrested.
What does get me down in the winter months is our overall lack of sunlight, and the dreary, overcast, chromatically-challenged days are more trying than a frozen beard.
