This is another stellar dendrite snowflake from January 2013. This snow crystal was difficult to work because it quickly melts at edges, while i captured series for averaging. Averaging photos with such serious differences leads to blurry zones (where melting occurs). So, i manually restored outer edges of snowflake using first photo from the series. 6 identical photos was averaged to boost signal-to-noise ratio of this image. Background: dark grey woolen fabric, natural light from cloudy sky, external optics Helios 44M-5, Moscow, Russia.
My processing workflow includes manual drawing precise mask at contour of snowflake (to being able process crystal and background separately), and i used this mask again for variant with blurred background:
