NiSi and Haida both make neutral density (ND) filters for long exposures, and both lines have loyal followings among landscape and video shooters. The right choice depends less on the logo than on the filter system you use, the density you need and how much color cast you will tolerate.
What ND Filters Do
A neutral density filter darkens the whole scene evenly, letting you use a slower shutter speed or a wider aperture in bright light. Typical uses include silky water, blurred clouds and smooth video motion at a normal shutter angle.
- A 3-stop filter allows roughly eight times longer exposure.
- A 6-stop filter is a common choice for flowing water in daylight.
- A 10-stop filter turns minutes of exposure into possible results at midday.
Where These Two Lines Differ
| Question | NiSi ND | Haida Red Diamond ND |
|---|---|---|
| Formats offered | Round and square holder systems | Round and square holder systems |
| Marketing angle | Neutral color and landscape use | Multi-coated glass and strong build |
| Typical buyer | Landscape and travel shooters | Landscape, video and long exposure users |
Both makers sell several series, so a model name matters more than the brand. Read the product page for glass type, coatings, density options and holder compatibility, and do not assume that every series within a brand behaves the same.
Things That Matter More Than Brand
- Choose a format. Round screw-in filters are compact and simple. Square filters in a holder let you slide a graduated filter over an ND and share one set across lenses.
- Choose a density. Many people begin with a 3-stop and a 6-stop, then add a 10-stop later.
- Check for color cast. Very dark filters can shift white balance, which is easy to fix in raw but harder in JPEG.
- Check for light leaks. Long exposures can let light enter around the filter edges, so use a cap or cover over the viewfinder on DSLRs.
Shooting Tips for Long Exposures
Compose and focus first, then mount the filter, because autofocus and live view struggle in the dark. Use a sturdy tripod and a remote release or the self timer. As a general guide, switch to bulb or manual mode and calculate exposure using a phone app or a chart, since metering often fails through dense filters.
FAQ
Are variable ND filters a better option?
Variable ND filters are convenient, but they can show uneven darkening or a dark cross pattern at high density, mainly on wide lenses. Fixed filters are usually more predictable for serious long exposure work.
Do I need a stack of filters?
Not at first. One or two fixed densities cover most daytime scenes. Stacking adds glare risk and corner darkening, so add filters only when a scene calls for it.
The Short Version
Choose NiSi if its filter system and holder fit the lenses you own and you want a landscape focused range. Choose Haida Red Diamond if its multi-coated glass and format options suit your workflow. Compare exact model specs on both makers’ pages before you buy.
