“The Snowflake” is finally complete. 2500 hours across 5 years, this poster print represents that largest project I have ever undertaken. Depicted in this image is over 400 unique snowflakes, all accurately measured and scaled to that they are all in relative size to one another. The poster print is currently available for pre-order shipping in January, but I have “artist’s proofs” available right now that I’ll be shipping as the orders are placed. Take a look! skycrystals.ca/poster/
On average, 40 separate images are combined for each snowflake photograph. This is required to get the crystal in focus from tip to tip with a process called focus-stacking. Due to the nature of the subject and the hand-held approach to photographing each snowflake, 4-5 hours are spent on each image in post-processing.
Measuring snowflakes is a time-consuming task, and the right equipment is needed to get accurate results. Thankfully, a hidden piece of metadata recorded by the Canon MP-E 65mm F/2.8 1-5x Macro lens makes this possible: the magnification factor. Combined with the physical size of the sensor and the total number of pixels across the sensor, an algebraic equation allows us to calculate the number of pixels per millimeter and measure the crystals.
The process of measuring snowflakes is made more difficult by the removal of certain metadata when editing. The “magnification factor” value is stored in a special area of image metadata called “makernotes”, and can be extracted by tools such as exiftool. This special section of metadata is removed from the file when processed through any Adobe software (and I’m sure others), requiring me to revisit the original raw files for each snowflake to obtain the proper value.
The largest snowflakes measure just over 11mm in diameter, and the smallest are 0.2mm across. Different storms create different kinds of crystals, some symmetrical but always unique. No two snowflakes falling from the sky will ever be identical. This poster shows the beauty in their variety.
This print not only shows the beauty of winter, but it’s an eye-opening experience when you dive into the details. The working file on my computer is 12 gigapixels in size, so I could theoretically make 60” x 90” print at 480dpi if I wanted, losing no detail in the process. When working on the file, my computer uses over 100GB of RAM, so creating something like this required impressive technology to boot.
Five years of photographing snowflakes, all with the same technique. I knew there was a reason why, and here it is: “The Snowflake”. Please let me know your thoughts!
La couleur de la mer, la couleur des rochers, les îles dans le lointain, les voiles, la forme des nuages, le splash sur la tourelle.
(français simple) C'est une installation artistique au musée de Nantes. Le nom de l'artiste est Susanna FRITSCHER. Le nom de l'œuvre est « Nur mit Luft, mit Licht und Zeit ». L'œuvre est un labyrinthe. Le labyrinthe est fait avec des fils en silicone. La vue des personnes est changée dans le labyrinthe. Les fils de silicone changent la perception visuelle.

This is, by far, the most scenic outhouse I’ve ever encountered.
This is a panorama of 9 shots but cropped quite a bit down from there. Nikon Z6 with Z 14-24mm f/2.8 S lens @ 14mm, f/2.8, ISO 3200, 20 seconds for all shots. I didn’t need a separate foreground pano because there was plenty of ambient light from the lighthouse and town behind me.
The raw files were converted to DNG files and then their built-in lens profiles stripped (using exiftool) to get around a limitation in Lightroom that forces built-in profiles to be applied on some camera models (apparently this isn’t an issue with newer cameras supported by Lightroom), which results in banding issues due to the sub-par warping used to correct distortion in Lightroom. Removing these profiles gets rid of this issue, more information about that is in my book, “Night Sky Photography”. You can also edit the files in a raw converter that lets you disable the profiles, like Capture One, which I sometimes do. After basic editing to manually remove lens vignetting, white balance, etc, I then exported the images to 16-bit ProPhoto RGB TIFF files for processing in PTGui to generate the pano, then creative edits in Photoshop to bring out the details.
