The spring torrent of cascade creek fills its narrow canyon with mist behind trees growing among the rocks.
I’ve been sitting on this second photograph of Cascade Creek, shot back near the beginning of June, trying to make some decisions about cropping and so forth. I finally have decided that I think I like this somewhat unusual (for me, at least) square format for this image.
Cascade Creek crosses beneath Big Oak Flat Road as it descends toward the Merced River and Yosemite Valley. For a few weeks during the spring snow melt season it can turn into a powerfully flowing stream, whose power is amplified by the steep descent and narrowness of the rock channel it follows.
The spring torrent of Cascade Creek descends past Big Oak Flat Road on its way to the Merced River, Yosemite National Park, California.
Every year, but especially in years of above average precipitation, this cascade flows strongly in the early season as low elevation snow melts above Crane Flat Road. The creek, swollen with runoff, drops down a narrow slot above the road, passes under the bridge, and continues its descent to join the Merced. This year the cascade was very full during my first-week-of-June visit, and even though I’ve photographed it before I had to stop again.
Lighting can be tricky here. The water is deep in the cleft in the rocks, so it is much darker and the light is fairly blue. The direct sun was lighting the foreground trees, which are much brighter and warmer in color than the background. I was lucky in that the waterfall and some morning breezes were raising a good deal of mist, which alternately obstructed the view of the fall and cleared away to show some of the trees. At the moment I made this exposure the shadows of trees outside the frame were creating shadows in the cloud of mist.

Water cascades over moss covered rocks along Redwood Creek at Muir Woods National Monument.
I made this photograph on a low-light end-of-autumn day at Muir Woods where the first bridge on the main trail loop crosses over Redwood Creek. It was no problem getting a long enough exposure in this low light – in fact, the main technical issue here involved waiting for a break in the tourist hiker traffic across the bridge, since the bridge is small and tends to bounce!
I love Muir Woods during the dark and damp season of late fall and early winter. The direct sunlight does not often make it down into the bottom of this cold canyon at this time of year. The light is almost always soft and diffused and when everything is a bit wet – e.g. most of the time – the colors becomes intense and saturated.

We had hiked up through this meadow filled with plants and wildflowers earlier in the day while walking a circuit that included Hungry Packer Lake (beyond the saddle seen in the distance and below Picture Peak), Moonlight Lake, and Sailor Lake. At that time the early afternoon light had been far too harsh for photography, so I made plans to be back here early in the evening. I had hoped for some “golden hour” light, but I have to admit that I could see that a ridge to the right was going to cast a shadow here too early for that. Fortunately, the light on the peak came from the side such that it wasn’t as much brighter as it might otherwise have been, and it seemed like it might be possible to capture the huge dynamic range of this scene.
That last point brings up a difficult technical issue with this photograph – that tremendously large dynamic range. Although my eyes/brain could take in the full scene while standing there, no camera that I’d be carrying on the trail can possibly deal with this in a single shot. In the foreground the meadow plants were in early evening/late afternoon shade while the cloud above the peak was brightly lit by the direct sun. In the film days the only real option would have been to use a graduated neutral density (GND) filter to reduce the light from the sky. However, with digital capture we have another alternative – capturing several exposures of the scene optimized for the bright and dark areas and then combining them in post-production. That is precisely what I determined to do here.
In this case I made a main exposure that handled the middle of the dynamic range of the scene. I also made two more; one optimized to barely contain the brightest levels in the cloud and the second optimized to capture all of the details in the darker foreground meadow. The three versions of the scene were combined in post-processing to recreate something much closer to what I actually saw. (Yes, this was a complex photograph to realize!) in addition to using three exposures, I was also able to carefully customize the boundaries between them issuing masks – both of which would be impossible with a GND filter.
