My technique for snowflakes shooting

  >> Russian version of this post
  >> Chinese (Traditional) version translated by Hung Li. Many thanks!

From all photography, my main interest is macro shooting of real snowflakes. Currently, i use low cost variation of well-known reverse lens macro technique: compact camera Canon Powershot A650is at maximum optical zoom (6x) shoots through lens Helios 44M-5 (taken from old film camera Zenit), reversely mounted in front of built-in camera optics. Compared to Canon A650 standard macro mode, this simple setup achieves much better magnification and details, lesser chromatic aberrations and blurring at image corners, but also very shallow depth of field.

I capture every snowflake as short serie of identical shots (usually 8-10, for most interesting and beautiful crystals - 16 shots and more), and average it (after aligning, for every resulting pixel take arithmetical mean of corresponding pixels from all shots of serie) at very first stage of processing workflow. Averaging technique dramatically reduces noise and reveals thin and subtle details and color transitions, which almost unseen in every single shot from serie, because they masked by noise.

Camera works with CHDK - Canon Hack Development Kit: often it named "alternate firmware", but actually this is resident program, which placed on SD card. It autostarts when camera turned on and greatly enchances camera functionality. CHDK is not nessessary for this type of shooting, but it is extremely useful, because it writes RAW shots as well as standard JPEGs and able to execute scripts (i use script Ultra Intervalometer with zero delay between succession shots: it works as continuous serie of shots with autofocusing before each of them). CHDK is extremely powerful tool, and i highly recommend it to any photographer with compatible compact camera.

My technique is very inexpensive (i already had a camera and all components, and it costs me no money at all). I think, almost any compact camera can be used for this macro setup, preferrable one with good optical zoom and sensor with more megapixels.

My shooting place is open balcony of my house. I was lucky that i have such nice place, where nobody disturbed me and i can return into house when i freeze.

In the beginning, 6 years ago, i shoot snowflakes with just camera, without any add-ons, in standard macro mode. Canon Powershot A650 have 12 megapixel sensor and very good macro mode, with focusing ability started at 1 centimeter from the lens. This is enough for taking good snowflake shots, but in low resolution, because i cut only small central part of whole shot with snowflake and some surrounding background:

source shot, 4000 x 3000processed picture, 800 x 600
Darkside, snowflake source photoDarkside, processed snowflake image

Depending of snowflake size, final resolution of picture varies from 640x480 pixels to about 1024x768, not more. This is enough for internet posting or making collages, but not for prints.

That times i captured snowflake with two methods: dark shots with bright snowflakes taken in natural light (usually it is diffused light of gray cloudy sky), using as background dark gray woolen fabric or green plastic carpet. I place this background at stool and, when good looking crystals falls on it, start shooting, touching background with hands and camera for steady shots. Camera shoots in macro mode from minimum possible distance. I only select in camera menu focusing by central point instead of auto focusing at multiple zones, so i able to focus precisely at center or front edge of crystal; and select exposure metering mode to central spot instead of evaluating from whole frame (this is nesessary, because with dark background and small bright snowflake automatic metering completely overbrightes crystal).

The other method, which i use for bright pictures with silhouette of transparent snowflake on it, is shooting at glass surface with backlight. For this, i place at floor of balcony turned upside down stool, and at it legs, horizontally - large sheet of glass. For being able shooting vertically down without any camera shaking, i make simple tripod replacement: from small plastic bottle i cutted out central cylindrical part in form of short tube. I choose length of this tube such that camera's lens, putted into it, do not reach other edge of tybe 1 centimeter (this is my minimum focusing distance of camera). When snowflakes falls at glass, i just put this tube with camera over a snowflake and shoot with 2 second delay (selected in menu), so i can remove hands from camera. With other hand, i light snowflake from bottom of the glass using simple LED flashlight. Light is stround enough for shooting even at night with short exposure time and at lowest ISO.

Some examples of snowflake pictures, taken in standard macro mode: old snowflake shots, 2009-2011.

Two years ago, instead of taking single shots of each snowflake, i started to capture short series (usually 8-10, sometimes more) identical shots for each crystal. This serie averaged and merged into one picture - it helps greatly to lower picture noise (or, in other words, boost signal-to-noise ratio) and reveals small and subtle crystal details, which almost invisible in every single shot, because they masked by noise level. I wrote separate post about averaging identical shots.

This animation shows difference between single JPEG from camera and averaged stack of 12 identical RAW shots:

One year ago i started to use external optics for better magnification of snowflakes, and built very simple optical add-on for my camera. This macro setup based on Helios 44M-5 lens.

lens Helios 44 magnification

At first, i attached lens at narrow wooden board (around 30 cm long), reversed (back lens to shooting object, front lens to camera), and drilled in a board an opening for screw, suitable for tripod nest of camera. Then camera mounted on a board so that the built-in lens in the maximum optical zoom mode (6x) touched Helios lens and looked straight into it. I attached the camera with a screw and additionally with metallic bracket, glued to the board: it holds opposite side of camera, so it didn't move anywhere. On Helios back side (which is front side of whole construction) i attached three standard narrow extension rings from Zenit camera (this is nessessary only in case of shooting at glass surface with backlight, in all other cases i do not use them). These rings keeps lens at needed focusing distance from the glass with snowflakes (2,5-3 centimeters). Place of connection between internal and external lens i covered with some sort of skirt, maked from black plastic bag: this protects connection point from outer light, snow, ice and waterdrops. Whole design turned out rather strong and steadily stands vertically with lenses looking down. I simply put it on glass over the chosen snowflake and shoot in maximum optical zoom mode. Camera's autofocus works fine through external lens. For shots at dark background, i just use small desktop tripod with flexible legs, which i attached to back side of wooden board.

I capture snowflakes in two modes:

1. At horizontally placed glass sheet with backlight. My macro setup stands vertically at glass with optics looking down, i simply put it over chosen snowflake and shoot short series of identicals shots (usually 8-10, for most interesting snowflakes - even more). From bottom side of the glass i light snowflake using LED flashlight with diffusor (part of plastic bag), for more uniform light. I try to point flashlight not vertically up, but at some angle, then crystal looks more volumetric, with dark and light contours.

2. At dark opaque background: woolen fabric. For these shots i use only natural light of cloudy sky. I shoot at angle: far side of wooden board, at which Helios and camera mounted, stands at small desktop tripod with flexible legs, and i can easily adjust angle, at which camera looks at background. Near side of board with front lens lays at background. I shoot serie for one crystal and then move macro setup to new crystal.

Shooting is easy, but processing of picture takes significant time. At first, i align and average my series of identical shots. Then i do standard postprocessing: sharpening, additional noise removing, cleaning background from ice debris and unwanted adjacent crystals, color toning (i prefer adding blue colors to my shots: originals almost monochromatic gray and looks not appealing, at my taste) and finally, contrast curve.

This is an example unprocessed shots in two modes: standard Canon A650 macro mode and with external lens. Please click at images to open them in full 12 megapixel resolution:

Also i prepared another before and after comparison table with unprocessed shots (straight out of camera) and final pictures.

When processing, i add to snowflakes some artifical colors, if they turn out too monochromatic. For latest shots i use simple multi-coloured lighting: i put a fragment of semi-transparent plastic bag with any color pattern on flashlight (for example, white+orange or blue+white+yellow colors). Because i hold flashlight far enough from glass with snowflake, i got smooth color gradient instead of pattern on background + multi-coloured facets of the crystals. Even if i don't like colors on source shots, this is no problem: i can easily convert colors to more pleasant ones using curves in LAB color space.

Snowflakes with clearly visible thin film interference effect (it described in Wikipedia). Same effect produces rainbow colors in soap bubbles, for example. Unlike bubbles, in snowflakes this effect can be seen only occasionally: if snowflake contains air cavities in the center, and interleaved layers of ice and air are very thin:

  12. Dziekuje :) Twoje śnieżynki sa piekne :)

  13. Thank you for your great work!

  14. Hey, I've red on forums that screwing out first two lenses of Helios (from mounting side) improve macro picture quality of helios. Do You know anything about it ?

  15. Hi

    Great pictures does this work with other Helios lenses such as the HELIOS-44M-4

    1. Thanks! I think, other lens will work too, but this needs to be tested.

  16. Absolutely amazing! You Sir, are a genius, and your photos are brilliant!!! Simple, -yet it's a very effective set up.

  17. I had to try it myself and discovered that this is very hard. Insects and spiders are much easier because of the time frame to have to take the picture. Thank you very much for sharing your excellent work. You are a true inspirer and I will come back again and again.

  18. is it true that not one snowflake is alike. amazing photos

  19. It's a beautiful work!... REALLY LOVE IT!
    thanks for sharing~

  20. Wow, this is awesome. I would like to try it but snow is rare here in florida. I guess is time to start scraping the walls of my freezer and see what happens...

  21. Ingenious setup for macro photography. You have "Zolotie ruki"

  22. Thanks a lot for this ! I built my own and really enjoy making photos and videos using your technique.
    And bravo for your fascinating snowflake pictures ! Strange how they always have 6 sides...

  23. Thankyou! Amazing! and Thankyou!
