I was out chasing waterfalls last month and took this. Processed with darktable nightly build. Because of all the detail it was a good photo to test the capabilities of the new contrast & texture module.
Went with a vertical crop to reduce the overwhelming effect of the colorful foliage and to bring out the echo of the square peg in the foreground without feeling the need to reduce the high contrast look of the lens.
Lots of little details that can be attended to in this beautiful shot. Per my usual approach, I tried to make the most of the depth in the image as well as the foreground interest.
