A practical step-by-step guide to using a 10-stop ND filter for long exposure daylight photography, including exposure settings, focusing, and common mistakes.

Quick answer

Mount the 10-stop ND filter, set your camera to manual mode, and increase exposure time by 10 stops from your unfiltered meter reading. Focus before attaching the filter, then use a remote release and tripod to avoid shake.

Why a 10-stop ND changes your workflow

A 10-stop neutral density filter reduces light by a factor of 1,000, turning a 1/125s shutter speed into an 8-second exposure in bright daylight. That shift makes a tripod and remote release essential, and it also means you must focus before the filter goes on because autofocus can struggle through dense ND glass.

When a 10-stop ND is the wrong tool

If you need motion blur in low light or want to handhold, a 10-stop filter will force shutter speeds that are too long without a support. For scenes with moving subjects you want sharp—like street photography—a lighter ND or no filter is more practical. Also, stacking a 10-stop with a polarizer can cause vignetting on wide lenses; check your lens diameter and filter size first.

Step-by-step setup for a 10-stop ND long exposure

Mount the camera on a sturdy tripod: Set up your tripod and compose the shot before attaching the filter. Use a remote release or the camera's self-timer to avoid touching the camera during exposure. A flimsy tripod will vibrate in wind; hang a bag from the center column for stability.
Focus and set exposure without the filter: In manual mode, meter the scene and note the shutter speed at your chosen aperture and ISO. Focus manually or autofocus on your subject, then switch the lens to manual focus to lock it. Do not rely on autofocus after the filter is on—dense ND glass can prevent the camera from focusing accurately.
Attach the 10-stop ND filter: Screw the filter onto the lens carefully, avoiding cross-threading. If your lens uses a different thread size, use a step-up ring. Check for fingerprints or dust on the filter before shooting; clean with a microfiber cloth.
Calculate and set the new shutter speed: Increase the unfiltered shutter speed by 10 stops. For example, 1/125s becomes 8 seconds, 1/60s becomes 15 seconds, and 1/30s becomes 30 seconds. Set the camera to Bulb mode if the calculated time exceeds 30 seconds. Use a stop chart or a calculator app to avoid math errors in the field.
Take a test shot and adjust: Fire a test exposure and check the histogram. If the image is too bright, shorten the time or stop down the aperture; if too dark, lengthen the time. Adjust in 1/3-stop increments as needed. A histogram biased to the left is normal for long exposures; avoid clipping highlights.
Enable long exposure noise reduction: Turn on your camera's long exposure noise reduction (dark frame subtraction) if available. This doubles the exposure time but reduces hot pixels and noise. For exposures over 30 seconds, bring a stopwatch or use an intervalometer.
