For these two pictures, i’ve used blending mode difference again, for subtracting original background (smooth blue / gray gradient) and revealing snowflake with all details on pure black. This time, i’ve divided picture by two halfs, and replaced one with part of original photo; and picked two small hexagonal plate crystals as sources:
Snowflake picture: Harlequin. Full size: 1024 x 768 pixels
Snowflake picture: Harlequin II. Full size: 1200 x 900 pixels
