Long exposure of a rocky cove at dusk. Dark craggy cliffs frame silky white water swirling around sea stacks, with a pink and lavender sky fading to the horizon.
Arched Rock Beach in Sonoma Coast State Park near Carmet, California, at sunset. The naturally arched sea stack stands among scattered dark rocks in the surf, with long-exposure waves blurred into a soft mist across the beach. The sky glows in bands of orange, pink, and purple above the horizon, with a coastal headland and a few vehicles visible along the cliff to the right.
Golden Gate Bridge spanning San Francisco Bay, viewed from the Marin Headlands. The bridge's red-orange towers and suspension cables stretch across calm blue water, with a hazy San Francisco skyline visible in the misty background. A grassy hillside slopes down in the foreground on the left.
