My wife and I recently took a long weekend in Wisconsin and rented a house right on Lake Michigan. You know I couldn’t resist. One morning I got up before everyone else, grabbed my gear, and walked down to the shoreline to wait for the sun. What I love about this spot is the way that first light skims low across the rocks and lights them up in warm gold, while the lake still holds that cool blue. The waves were rolling in hard against the shore, and I knew right away I wanted to show their motion, not freeze them. Here’s what I used to create this photograph: Nikon D850 on a tripod 24–120mm f/4 lens 3-stop neutral density filter 1 second · f/22 · ISO 32 Why those settings? The secret to this shot is the shutter speed. At 1 second, the moving water turns soft and misty, but the waves still keep their shape and energy. Go too long and the lake flattens into fog; too short and it just looks like an ordinary splash. One second was the sweet spot for these waves. The problem is that even at sunrise, there’s a lot of light coming off the water. To get down to a 1-second exposure, I had to stack up every tool I had: - ISO 32 – the D850’s lowest setting (Lo 1), to make the sensor as insensitive to light as possible - f/22 – a small aperture to cut light further and keep the rocks sharp from front to back - A 3-stop ND filter – like sunglasses for your lens, it blocks light so the shutter can stay open longer And of course, a sturdy tripod. At 1 second, the rocks would never be sharp handheld. A few composition notes: - The shoreline makes a strong diagonal that pulls your eye from the bottom-left corner out to the waves breaking in the distance. - I kept the horizon high in the frame because the real story was down in the rocks and water, not the sky. - I got low so those foreground stones feel big and close, with texture you can almost feel. Your turn: Have you ever tried a long exposure with moving water: waves, a waterfall, a creek? Post one in the comments! And if you’ve never tried an ND filter, tell me what’s holding you back.
