This was such a fun conversation. Give it a listen!

Electric Spice Enjoy mustard? I love the seeds as a spice, the greens as a salad, and the view of the plant fluorescing under ultraviolet light. I especially love that they are so vibrantly fluorescent, such images ...

If you want to know how to get the most out of your phone for macro work, I've also got a workshop coming up soon: princetonphotoworkshop.com/classes/phon...

Snowflake 977

This snowflake was photographed two days ago on the Black Sea coast of Bulgaria. The conditions rarely allow for such things to form here, and I'm pretty happy about it. :)

Snowflake 976 While not a “classically defined” snowflake type, I’ll refer to this one as a “cascading dendrite”. The central spokes here have a unique quality: they cascade their thickness to lower levels closer t...

I'll call this one a "cascading dendrite". Read the post over on Flickr to see why! They're truly beautiful things.

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

Writing and acting-wise, I completely agree with you. Even the camera work. As for the sanitization/sterilization aspects of how they work, I need to suspend my disbelief. Though I get how it could de-personalize moments that you really need to "feel" what the people are going through.

Prismatic Crystal - Snowflake 971 This is something special. It may have been difficult to notice the prismatic colours in the fully focus-stacked version of this snowflake (seen here: flickr.com/photos/donkom/55032219125/ ), but here...

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. :)

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.

Tough to find the words to welcome in the new year. Wishing everyone well, and hoping for a calm start to 2026. Happy New Year!

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

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!

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.

Close-up of the super-cooled water droplets, some staying as spheres while others begin to form crystals - some radial, some parallel to the main snowflake's growth plane but not linked to the original molecular lattice.

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...

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.
