Snowflake-a-Day 2016-2017

Snowflake-a-Day #2
From elaborate and ornate branches to the tiniest hexagonal crystals, snowflakes of all sizes can spark your curiosity – especially when there are interesting colours to discover inside of the snowflake itself! A simple snowflake but with some of my favourite features, view large!
Some features of this snowflake are close to symmetrical, but even the tiniest variance in accumulation along different sides can break the symmetry early. This snowflake is fighting for a unique kind of symmetry – three fold – where alternating sides are more similar. This is often caused by the aerodynamic properties of how a snowflake is spinning (or falling in a very stable pattern) which can result in more dramatic triangular crystals. While the symmetry is interesting, by far the best part of this snowflake is the colour.
The brighter and mostly coloured areas of this snowflake are caused by bubbles in the ice. These bubbles create multiple surfaces to reflect light back to the camera, which is why they are brighter than the surrounding ice. They don’t just become brighter, in certain circumstances they also become vibrant. The physics is basic: thin film interference. Soap bubbles, oil, and even some inks can create this visual effect; if you’ve ever seen a rainbow pattern in a soap bubble, you’re seeing the same phenomenon at work here.
If some light reflects off of the front surface, and some also reflects off of the internal surface within the right thickness, the two beams of light are now out of sync because passing through ice slowed one of them down. The exact thickness of the ice will determine how far out of sync they are, resulting in optical interference that generates colours from white light. I’m not a scientist, but I find such things fascinating – all in the tiny world of a single sub-millimeter sized snowflake.
Photographing snowflakes at this scale can be difficult, but not impossible. I’m using the Canon MP-E 65mm macro lens coupled with extension tubes as well as a Canon Lifesize Converter (basically a 2x teleconverter for macro magnification) to push all the way up to 12:1 magnification, 12 times closer than a regular macro lens goes. The image still needs to be cropped in considerably, and this is 20 separate images stacked together to get everything in focus… shot entirely handheld.
I’m often asked why I shoot my snowflake images handheld, and the answer comes in two parts:
Time. A snowflake is actively sublimating and I need to work as quickly as possible to shoot all of the necessary frames. Give this tiny crystal five minutes and the outer outline will be considerably smaller. You can already see signs of the edges evaporating back into this are!
Angle. I need to rotate the camera around the subject to get the right angle of light from my ring flash to see surface reflections, like glare on a window. This surface reflection is required to reveal features like the colour, and often showcases surface details with far more accuracy. Because the camera needs to rotate in this way quickly, where no tripod mount can accommodate, I need to shoot freehand.
If you’re curious how exactly that’s done, you should consider picking up a copy of Sky Crystals, a book I published that gives away all of my secrets for creating images like this: https://www.skycrystals.ca/book/ - 304pg hardcover book that makes a perfect Christmas gift for any macro photographer! :)

Snowflake-a-Day #1
It’s that time again! This year’s series starts with a snowflake photographed at the end of last winter, as we haven’t gotten “the good stuff” yet this season. Be sure to view it large and enjoy the details!
This snowflake reveals some interesting details about these crystals, in a number of ways. The lighting on the center can quickly reveal the differences in depth and thickness of the crystal, with the light coming from the upper right, it falls off sharply on the lower left half of the center, This seems to mark a somewhat domed shape in the center, but that’s very difficult to explain. Usually, the areas that grow faster are the areas that stick out the farthest (more access to water vapour), so how does the center maintain a thicker profile?
I’m not sure. I might ponder on this one a little more or ask some people with an education that can help me find answers, but there has to be something more complicated at play here. I find these mysteries engaging and I don’t think I’ll ever stop asking tough questions about it!
Another curiosity that I CAN explain is the smaller lower left branch. If grown in perfectly balanced and even environments, snowflake will grow symmetrically. We’re seeing asymmetric growth that is mostly balanced, which means two things: Conditions average out over time to be equal, but some other snowflake was stealing building blocks on one of the branches. This is very common, and if you look closely you’ll see two “adornments” sitting on top of the main snowflake; two small simple hexagonal crystals.
What if one of these snowflakes landed near the tip of a growing branch? Or a larger crystal collided and stuck onto this snowflake? We’re guessing at shadows here, but something would have been attached to this branch to make it grow slower. Often times these hitchhiker crystals break off in the sky or on impact with the ground, but we can see the influence they’ve left on the surrounding crystal.
With snow right around the corner, wouldn’t it be great to try this yourself? I still have a few hundred copies of my book Sky Crystals left, with thousands already sold – get it while you can! The book not only details all the science, but gives an exhaustive photographic tutorial from equipment through settings, technique and post processing. Don’t let your macro lens collect dust this winter: https://www.skycrystals.ca/book/
This post is coming later that I’d like, as I’m quite under the weather and still trying to finish up studio renovations. There’s only so much time in each day…. and today was filled to the max! Expect another snowflake tomorrow, as winter begins its final approach. :)
