Just outside Betws-y-coed, in the heart of the Snowdonia National Park, North Wales, lies this hidden gem of a little river, the Afon Lledr.
At this early stage of its life the river flows through a secluded wooded glen, under an old stone arch bridge and over some fantastically water shaped rocks. (Very slippy!)
Accessed from a convenient layby, you have to push through some wild rhodedendron bushes to reach the river bank and then hazard those slippery rocks to reach this vantage point giving a view up the river to the old bridge and beyond.
Having got there on a lovely summer's afternoon I decided to make the most of my perch in the middle of the river to take the stills for this time lapse video, catching the movement of the water as it flowed along in brightly lit swirls and eddies.
In fact that bright light proved a problem, in that it was hard to find an exposure that didn't burn out the hightlights on the water and also preserved some detail in the darker areas of the frame.
But I found a reasonable compromise in the end, pushing the exposure as high as it could go without seriously damaging the highlights on the water.
That fine tuning, plus the fantastic ability of Adobe Lightroom to pull detail out of dark areas, resulted in this rather pleasant time lapse sequence.
And just to show how the scene looked in real time, I also shot a 'normal' video, Snowdonia River #1, from the same spot, although trying to pull shadow detail out in a video file proved a little more challenging than with the RAW still image files I used for the time lapse.
