Heavenly sight of the iridescent, crystalline stream at the Tolmin Gorges in Slovenia. This was a single exposure made with Canon 5D Mk2. To help with the creamy smooth water, I used the Tiffen 4-stop ND filter. Colours were punched with the Heliopan CPL filter mounted on the tremendous Canon TS-E 24mm lens.

Here's a detailed description of the Tolmin Gorges: The chute on the Tolminka River is the lowest point (180 m) in Triglav National Park and the longest chute in Slovenia. It is also among the deepest. The junction of the gorges of the Tolminka and Zadlaščica rivers with their chutes is a unique phenomenon in Slovenia. The chute of the Tolminka River is about two hundred meters long and five to ten meters wide.

The spring of thermal water (22°C) on the bank of the Tolminka just below the end of the trail through the chute is another great rarity in the alpine world. The well known Hudičev most ("Devil's Bridge") over which the Tolmin-Čadrg road passes arches sixty meters above the Tolminka, and above it is the entrance to the Zadlaška or Dante Cave. A triangular rock called the "Bear's Head" (Medvedova glava) after its characteristic shape is wedged in the narrowest part of the Zadlaščica chute.
