Here's a brief tutorial on how to get started with shooting freezing soap bubbles. Here's a full and comprehensive tutorial in my book: www.amazon.com/Macro-Photog...

Crystalline Connections – Freezing Soap Bubbles
Cold is gripping much of North America. I checked the temperatures in my hometown of Sudbury, Ontario this morning, and it was -32C / -26F. With these horrible storms set to arrive later today and wit...

Check out the center on this one, too! So cool how this forms, as well as how the bubbles form on the branches.

A lot of America is about to be covered in countless trillions of these. I personally find them beautiful individually, but there’s a snowstorm of the century arriving and I hope everyone stays safe! ...

The center of this one features a "skeletal form"-type crystal splitting, it's really fun to just observe how the #physics works.

Read the full post over on Flickr, the character count here doesn't do it justice. :)

A simple star snowflake, but with a very interesting center. Notice that the very center is solid? That’s an odd and wonderful feature that leads to layers! Imagine a hexagonal prism – it has a hexag...

Prismatic Crystal - Snowflake 971

A different view from the previous snowflake specimen that really focuses on the hidden colours - made much more visible when thrown out of focus.

The colours here are really special, not often to we see this much prismatic colour in the branches! Read the Flickr post for all the details. :)

This snowflake is special to me for many reasons. First, it’s a classic dendrite with a large geometric center. Secondly, it features a special type of colour in the branches that is always hard to ca...

One of the best examples of a thick snowflake causing inward crystal growth. There's a bit to unpack in the full description on Flickr, but this type of snowflake is one of my favourites.

This snowflake tells a very interesting story. Almost like the rings on a tree show its age, these rings radiating along this snowflake’s branches are a growth indicator. These are a function of thick...

Ever seen a thirteen-branched snowflake before? Well, you have now (sort of): www.flickr.com/photos/donko...

The full description doesn't fit here, but these are effectively crystal clusters. Read on Flickr for more. :)

I’ve seen thin film interference everywhere from a cup of Turkish coffee to the meniscus formed around the lid of fountain pen ink. Ever see “Newton’s Rings?”; it’s everywhere if you’re paying attention. Even in snowflakes!

Let’s talk about colour. Snowflakes are not flat, they have volume. That volume allows for air pockets to be trapped in the ice. Given the right thickness of the “bubble” and/or the right thickness of...

There's too much to say about this snowflake here and not enough space - but you can read all about it over on Flickr: www.flickr.com/photos/donko...

It attempts to unlock some mysteries as to how pockets of air form in these gems.

This one has a ton of volumetric details. Not only did it start as a "split crystal" to allow for overlapping branches, it also features collisions with super-cooled water droplets that form their own crystals. Full write-up here: flickr.com/photos/donko...

Macro lenses. Do you think I have too many?

I believe it’s safe to say I own an unhealthy number of macro lenses. I shot this updated photo from my new book, now available for pre-order! Link: www.amazon.com/Macro-Photography-Universe-Our-Feet/...

Finally, a chance to photograph a snowflake here in #Bulgaria! Problem is, it was melting as I photographed it. That leads to a unique set of challenges but also a rather unique look into the life of a snowflake.

Broad branches are always beautiful, as if this snowflake is a set of 7, including the center. Combined with a splash of colour from thin film interference, there’s charm here – but there’s also a mystery. The thin sections of the branches have a feature I can’t easily explain.

This is a delightfully odd and exotic snowflake; a variety rarely seen and doesn’t match any of the standard “types” of snow. I’ll call it a “scrolled plate that transitioned to needles”. That’s about as good as it gets!

There are so many varieties of snowflakes, but they break down into two primary categories: plates and columns. Columns can be quite enigmatic, while possessing a simple outline; it’s the details inside the crystal that make them special.

Bubbles! And lots of them. :)

One of the elements of my snowflake photographs: the black mitten. All of these images are shot on a mitten as the background.

The mitten was made by my grandmother; it is with sadness to announce that she passed away on January 1st of this year, peacefully and surrounded by family.

I call these “button gem snowflakes”, though they are a variation the split crystal form. If a column grows plates out of both sides, and one of the plates grows faster than the other on all size sides, you get this effect.

Merry Christmas! This one is quite special and unique, not only is it one of the rarest varieties of “crystal twinning”, it’s also the reverse side of a snowflake I originally published in 2016.

I have no record of a similar ice crystal ever being documented by anyone in history.

“Split” crystals begin from a central column-type crystal which grows hexagonal plates from both sides of the column. It’s always a race for these plates. If one corner of one plate grows out further than the same corner on the other end of the column, the race for that corner is won
