Long exposure photography is one of the most magical techniques in the craft. By holding the shutter open for seconds or minutes, you capture what your eye cannot see — silky water, ghost-like crowds, streaked clouds, endless star trails, glowing city traffic. The world, stretched out and smoothed over.
This guide walks through everything a beginner needs to start shooting long exposures: the essential gear, the settings that actually matter, and a simple first-shot workflow you can use at your local river or harbour. You will learn why a tripod is non-negotiable, when to reach for an ND filter, and the most common mistakes to avoid on your first outing.
What is Long Exposure Photography?
Long exposure photography means keeping the camera’s shutter open for a long time — anywhere from half a second to several minutes — so that moving elements in the scene record as motion while still elements stay sharp.
The classic example is water. A one-second exposure turns crashing waves into a soft, textured mist. A thirty-second exposure at the coast turns the sea into a flat, dreamlike sheet. Clouds, crowds, stars, traffic — anything that moves — get the same treatment.
The reason the technique feels so striking is that it shows what a scene looks like over time, not in a single split second. It is closer to a painting or a memory than a snapshot, which is why long exposures have such a distinct and cinematic quality.
Essential Gear: Tripod, ND Filters, Remote
Long exposure photography is one of the few techniques where the gear really matters. You cannot handhold a 30-second exposure, and you cannot shoot midday long exposures without darkening the light. A few specific tools make or break the process.
A Rock-Solid Tripod
Your tripod is the foundation of every shot. Even the tiniest movement during a long exposure will blur the whole image. Invest in a sturdy tripod — ideally one that lets you hang a bag from the centre column to add weight in wind.
Neutral Density Filters
An ND filter is dark glass that reduces the amount of light reaching the sensor. A 6-stop ND lets you shoot 15-30 seconds during golden hour. A 10-stop ND (often called a ‘big stopper’) lets you shoot multi-minute exposures in full daylight. Both are worth owning.
A Remote Release or Timer
Pressing the shutter button by hand introduces tiny vibrations. Use a cable release, a wireless remote, or the camera’s 2-second self-timer to fire the shutter without touching the camera.
Understanding Exposure Times for Different Effects
Not every long exposure needs to be 30 seconds. Different shutter speeds produce very different effects, and part of the skill is choosing the right length for the scene.
1/2 Second to 2 Seconds
Short long exposures keep some texture in the moving element. Waterfalls retain their character but look smoother. Traffic shows trails of light but not long streaks. Perfect for adding movement without losing all detail.
5 to 30 Seconds
Medium long exposures give you the classic look — silky water, streaked clouds, clear light trails from cars. Most landscape long exposures sit in this range, especially at golden and blue hour.
Multi-Minute Exposures
A 2-minute or longer exposure turns the sea into fog, crowds disappear entirely, and clouds record as streaks across the sky. This is where the strongest long exposures become almost abstract — worth experimenting with once you have the basics down.
Your First Long Exposure: Step-by-Step
Here is a repeatable workflow for a first long exposure at a river, coast or busy street. Follow it carefully and your first results will look professional.
- Set up the tripod on stable ground and lock all legs.
- Compose the shot without any filters — check the corners for anything distracting.
- Set the camera to manual mode, aperture around f/8 or f/11, and ISO at its base (usually 100).
- Take a test shot and read the shutter speed the camera suggests.
- Attach your ND filter, then calculate the new shutter speed using the filter’s stop value (apps like PhotoPills do the maths for you).
- Switch to manual focus (autofocus will hunt through dark ND glass), fire the shutter via remote or timer, and wait.
Once the exposure finishes, check the image for sharpness, exposure and any light leaks through the viewfinder. Cover the viewfinder for very long exposures if your camera has a built-in shutter or cover — sneaky light can bleed in through the eyepiece.
Creative Subjects Beyond Waterfalls
Waterfalls and coastlines are the classic long exposure subjects, but they are far from the only ones. Once you start looking, there is movement everywhere that can become art.
Traffic at Night
Bridges, roundabouts and motorway overpasses at dusk turn into rivers of red and white light. A 15-30 second exposure at blue hour, from a safe vantage point, is one of the easiest spectacular long exposures you can shoot.
Clouds and Skies
A minute-long exposure turns moving clouds into soft, painterly streaks. Pair a 10-stop ND with a strong landscape foreground and you will get a dramatic, almost otherworldly sky.
Crowds and Public Spaces
A long exposure in a busy station, market or plaza removes the moving people and leaves only the architecture. It is a brilliant technique for showing a city space as if it were empty — ghosts of commuters barely visible in the final frame.
Stars and Star Trails
At night with no light pollution, a 20-30 second exposure gives you sharp stars. Multi-minute exposures or stacked sequences turn those stars into circles of trails around the celestial pole.
“Photography is painting with light.”
Daytime Long Exposure with ND Filters
Long exposures in bright daylight only work with neutral density filters. Without them, any shutter speed slow enough to show motion will blow the image out completely.
Choosing the Right ND
For most situations, a 6-stop ND works well at golden hour and a 10-stop ND works well in full daylight. A variable ND (which lets you dial in between 2 and 8 stops) is a useful all-in-one starter filter, though image quality is slightly lower than a fixed ND.
Focus and Compose First
Always focus and compose before attaching the ND filter. The filter is so dark that autofocus will fail and you will struggle to see anything through the viewfinder. Lock focus first, then add the filter.
Watch for Colour Cast
Cheap ND filters often add a colour cast (usually a magenta or blue shift). Good-quality filters are optically neutral. Any remaining cast can usually be corrected in post with a white balance tweak.
Micro FAQ
How long is a long exposure?
Anywhere from about half a second upwards. Most classic long exposures run from 5 to 30 seconds, with multi-minute exposures used for more extreme effects.
Do I really need a tripod?
Yes. Long exposures require the camera to be perfectly still for seconds or minutes at a time. Handheld long exposures are impossible in any meaningful sense.
Which ND filter should I buy first?
A 6-stop ND is the most versatile starter filter. Once you know you enjoy the technique, add a 10-stop for full daylight and multi-minute exposures.
What aperture and ISO should I use?
For maximum sharpness and minimum noise, use your base ISO (usually 100) and an aperture around f/8 to f/11. Wider apertures reduce depth of field; narrower ones start to lose sharpness due to diffraction.
Why do my long exposures come out blurry overall?
Usually either tripod movement (wind, soft ground, hand on the centre column) or slight mirror or shutter vibration. Use a remote release, enable mirror lock-up or electronic shutter, and weigh down the tripod.
Final Thoughts
Long exposure photography is a brilliant way to slow down and see a scene differently. Instead of reacting to a single moment, you set up carefully, plan your exposure, and let time do the creative work. The results often feel closer to painting than photography.
Start simple. A tripod, one ND filter, a nearby river or coast, and an afternoon of patient practice will give you images that look dramatically more accomplished than anything you could shoot handheld. Once you are comfortable, the creative range is huge — from dreamy seascapes to ghostly crowds to multi-minute night skies.
