Under the grey sky

Under the grey sky, dark collage with grid of square tiles, containing real snowflake macro photos on blurred background
Snowflake collage: Under the grey sky. Full size: 3661 x 3661 pixels

For this collage i used special variants of four snowflake photos. When processing each snowflake, i draw by hand precise mask, which separates crystal from background (i need it for processing object and background with different sharpening and noise removing settings). Drawing these mask is time consuming work, and requires lots of patience; but automatic methods of edge selection, which i've tried, do not provide enough quality. Now masks was used to blur background around snowflakes.

I'm not sure that these variants are good, though, because original background is visible through transparent crystals. You can see original snowflake photos: Rigel, Leaves of ice, Alioth and Vega on unchanged background.



Dark grey woolen fabric looks quite strange on high magnification, and i cannot say that wool fibers looks beautiful. On the other hand, these thin and rigid fibers are works really well for shooting process: they effectively trap snowflake and prevent wind to blow it away; also, snowflake usually hangs in the air above wool fabric, touching fibers only at few points. This slows down melting, which is very important in warm days, when temperature is too close to freezing point.

You can see visual difference in size of crystals in this collage, and it is real: all four snowflakes was captured at same distance from the lens and with fixed magnification, and i do not re-scaled photos on post-processing stage.
