Frost crystals (II)
Another look at frost crystals, growing on a grass blade this time:
The background is color is from leaf beneath the grass blade. Like the last crystal image, this is a stack of images that were combined for greater depth of field. The magnification is around 2x or 3x. Under the right conditions (temperature among others) frost grows in regular snowflake-like forms. Other times the crystals are fine rods, sometimes pipes, sometimes fern or leaf-like forms – the variety of forms is amazing.
