Despite many visits to Diamond Beach over the last half-dozen or so years, I still don’t feel like I’ve mastered the iceberg blurred water shot to my complete satisfaction. But I keep working on it, and this year I was at least was able to capture something I like.

In previous visits, when my attempts to capture the perfect motion blur shot failed, I’d fall back on sunstar images—partly because I find them easier, but mostly because the backlit translucence of an iceberg is spectacularly beautiful. But as much as I like these sunstar images, I’ve seen other photographers’ Diamond Beach flowing surf images that I like even better, and can’t help going for my own.

The problem (aside from only getting one shot at it per year), is getting all the scene’s many moving parts working together. Blurring a waterfall, or the whitewater of a flowing river or creek, is relatively simple because, even though the water is moving, the surrounding scene, including the position of the water feature itself, is stationary. And while crashing surf is fairly random from one wave to the next, again the surrounding scene (the beach or rocks upon which the surf is crashing) is fixed. But nothing at Diamond Beach is still for long.

Foremost among the Diamond Beach moving parts the frigid North Atlantic’s unpredictable power, which requires unwavering attention—in 2022, a rogue wave swamped four workshop members who reasonably believed their position above the beach was safe. Trying to coordinate all the other variables with one eye constantly on the ocean is the photography equivalent of patting your head while rubbing your belly.

The first essential element to consider is the location of whatever mini iceberg I target, which needs to be planted in sand, yet close enough to the water for an occasional wave to wash up and around it. Too far from the surf and the waves never reach the ice; too close, and the subject will actually float away mid-exposure. Often it’s difficult to tell whether a potential subject is properly positioned until actually attempting to photograph it for awhile. And even the best ice subject doesn’t in one place for more than a wave or two.

Adding more frustration to these Diamond Beach iceberg scenes is the power of moving water, which, even when it doesn’t reposition the ice, can still impart micro-movement during the long exposure. I can’t tell you how often I’ve thought I’d nailed a Diamond Beach shot, only to zoom in on the ice afterward to find an imperceptible rotation or wobble had made it too soft to use.

Then there’s the timing of the click. I’ve found that the most appealing blur happens when the wave has swept past the ice and is actually washing back out. Equally important is the duration of the exposure, which needs to be long enough to blur the water, but not so long that all definition in the water is lost. Even if I’ve nailed all the above variables, since I focus on my chosen ice subject before the wave arrives, even if it stays perfectly stationary during my exposure, just the slightest shift in the ice’s position before my shutter click can invalidate my chosen focus point.

Of course all these machinations are irrelevant to the people don’t like the silky water effect in any image. And while I agree that at times blurring water verges on cliché, the truth is that fast water illuminated by anything less than full sunlight usually offers little choice. In those conditions the question isn’t whether to blur the water, it’s how much to blur it?

The argument against blurring moving water that always amuses me most is the one that says blurred water “isn’t natural.” The reasoning is that blurred-water images should be disqualified because we never see blurred water in nature. My question for these “purists” is, how many times have you seen the alternative to blurred water: individual water droplets suspended in midair?

This question just underscores a photographic truth I’ve been hammering on for years: The camera and human eye experience the world entirely differently. Discarding images simply because they aren’t “natural” would eliminate not only all black and white images, but also every image that’s not, uhhh, three-dimensional. Hmmm—let’s count how many images that leaves us with….

On the other hand, embracing your camera’s unique vision is empowering. It opens doors to many creative possibilities, of which blurred water is just a scratch on the surface. While there’s no magic formula to achieve it, blurring water isn’t hard once you learn to see the world as your camera does.

The prime determining factor in blurred water is the distance any individual water drop traverses your frame while the shutter is open: the more of the frame it spans, the greater the blur effect. The amount of blur you capture starts with the speed of the water, over which you have no control. But take heart, because there are several variables you can control:

Focal length: The longer your focal length (more telephoto), the shorter the distance from one side the frame to the other (a wide angle vista can encompass many miles; a telephoto from the same vantage point can reduce the image’s width to a few hundred yards or less), so our imaginary water droplet will span a greater percentage of the frame’s width in a telephoto exposure.
Subject distance: Moving closer achieves the same thing a telephoto lens does because the closer you are to the moving water, the shorter the distance our water droplet has to travel to span the frame.
Shutter speed: The longer the shutter is open, the farther our droplet can travel during exposure. You can keep the shutter open by reducing your ISO, shrinking your aperture, and/or cutting the amount of light with a polarizer or neutral density filter.

Because long shutter speeds increase the amount of blur, blurring water is easier when you photograph in reduced light, such as overcast or shade, that requires a longer shutter speed. In full sunlight it’s pretty much impossible to blur water without a neutral density filter to cut the light illuminating the scene.

In a river or creek, whitewater generally works best because not only does it move fast, it also shows the blur effect much better than rapidly flowing green water. In other words, for any given combination of conditions and settings, while the amount of blur is the same for green water as it is for white water, the blur will be much more noticeable in the white water.

When the blur subject is ocean waves, there’s always an abundance of white water to work with. But rather than the relatively consistent flow pattern of river rapids, each ocean wave is significantly different from the others. I think this extreme variability from one wave to the next is what I most enjoy about ocean wave motion-blur images.

Approaching Diamond Beach this February morning, I scanned for ice in the narrow subject zone. I’ve had visits with more potential targets, but also some with less, so overall I was pleased with this year’s opportunities. I spent most of my time there strolling the black sand, working with workshop students, and occasionally targeting an ice chunk of my own for a few unsuccessful frames.

It wasn’t until I was confident everyone in the group was comfortable with the surroundings and happily at work on shots of their own that I got serious about my own photography.

I approached this little iceberg, maybe the size of a large microwave, and set up my tripod a couple of feet away. For the next 15 minutes or so, I worked carefully as up to 10 waves approached my subject, wrapped it, then flowed back out. Each wave nudged the ice slightly, forcing me to move my tripod and recompose before every frame.

Having an LCD and viewfinder to immediately scrutinize each capture was a huge advantage that allowed me to zero in on the shutter speed that worked for my focal length and distance, as well as verify the sharpness of my subject. Having waterproof boots that went up to within six inches of my knees was another advantage I quickly appreciated.

I still don’t think this Diamond Beach blurred wave image is as good as others I’ve seen, but I’m working on it…
