Which Nd Filter To Buy
Choosing what ND filter to cull is non easy as in that location are several things to consider. The density or strength of the ND filter is one of the choices that seem more than difficult when nosotros decide to buy one, in this article we will notice out how different Neutral Density filters create dissimilar furnishings on the photograph and how getting started is simpler than yous think.
Why buy an ND filter?
In simplest terms, an ND (Neutral Density) filter is the quaternary mode to manage light in your photography, the primary three being ISO, shutter speed and discontinuity. In landscape photography, these three tools are stock-still and therefore a fourth way is needed to manage the exposure, i.e. ND filters. Let's briefly come across why the 3 ISO settings, aperture and shutter speed are considered equally "fixed":
ISO
We want to go on the nominal value considering the sensor has the best performance at this value. Therefore greater dynamic range, less noise (and therefore greater item and prototype cleanliness). At most, nosotros vary 1-2 stops from the nominal value, the lower the better.
Discontinuity
Again nosotros want to ascertain the depth of field and the quality/sharpness of the image. There is a fairly narrow range where the lens has the best sharpness performance (unremarkably between f/8 and f/11). In addition, the aperture as well affects the depth of field, so nosotros desire to be sure that the whole field of view is clear and in focus (in most situations). In this case too we can vary nigh 1-2 stops, usually, the range is between approximately f/7.one and f/14.
Shutter Speed
Once the get-go two values have been defined, only shutter speed remains. And then if we want the photo to be correctly exposed, nosotros take to choose the simply value that satisfies the two above (with some tolerance betwixt 1 and four stops given the margins that we explained in the two previous paragraphs). Therefore there are but a few shutter speeds that can lead to right exposure, limiting our inventiveness. Because photography IS creativity and not mere execution, we need another tool to manage the light and allow united states to choose the shutter speed that we want.
This tool is the ND filter
We recommend reading our commodity showcasing some examples of the use of shutter speed and ND filters in landscape photography.
Which density/strength to buy?
This question has certainly crossed the mind of anyone budgeted ND filters for the kickoff fourth dimension, equally well as anyone looking to expand their creativity with new filters. The density is nada more than than the absorption factor of the filters, the higher it is, the more light is blocked and we have to increase the shutter speed to recoup. For more detailed explanations; you will observe an exhaustive caption of ND filters names and numbers here and in this article about how to calculate times with ND filters including a conversion tabular array.
The 3 most common ND filters are; 3, 6 and 10 Stop, their apply can exist described as follows.
3 Terminate ND filter (ND8, 0.ix)
Reduces light 8 times, so we have to multiply the shutter speed by 8 after inserting the filter. Information technology is not suitable for shots in very brilliant sunlight, but preferably from late afternoon to the evening after sunset. In the late afternoon it is useful to lengthen the time enough to make a slight motion in the waves, without making the whole bounding main silky. After sunset or in very low light, however, information technology tin can allow you to shoot even 1-two minutes or more of exposure. It is likewise used for photos of streams, rivers or waterfalls, especially in the wood where the light is already scarce.
6 Stop ND filter (ND64, 1.eight)
With this ND filter the light is reduced 64 times, so if we shoot for 1″ without a filter, we should become upwardly to 1 infinitesimal and iv seconds afterward mounting the filter (64″). Using a 6 stop ND filter it is actually useful to take a remote shutter release so you tin shoot over xxx″ in Bulb way (if your photographic camera has this limitation). A ND 6 terminate filter is widely used as a showtime filter, considering it allows y'all to take some long exposure beyond v-x seconds also in the afternoon, while at sunset and shortly after it allows yous to shoot for beyond ii minutes with petty effort. You can go cloud movement or very flat bounding main.
10 Cease ND filter (ND1000, 3.0)
With a light reduction of 1000 times information technology is one of the acknowledged filters to experiment the long and very long exposure from the early afternoon if the daylight is not as well harsh or at that place is cloud coverage. When light falls, the result is accentuated, all the same immediately after dusk or even a little before the shutter speed can be really very long (over v minutes).
Thanks to the availability on the market of the extensive NiSi range, it is possible to purchase most every density from 2 to xx Stops, thus leaving extreme freedom of expression. The 8 Stop is also a acknowledged product considering it allows you lot to obtain long and very long exposures even with the sun lower on the horizon, where a 10 stop would have been likewise much. While the 15 stop is perfect for long daytime exposures or in architectural photography. Read our guide about daytime long exposure.
Our advice in choosing the offset ND filter is to focus on the half-dozen or 10 Terminate, then once you have a piddling experience y'all will know if you want a 3 stop, an 8 stop or a fifteen stop as the second filter. Nearly photographers, over time, equip themselves with iii-four ND filters or more than, to have the greatest shooting freedom and expression possible.
Examples of different ND filters strength
When choosing the ND filter and the density, information technology is good to cheque comparative shots. Unlike exposure times, and therefore unlike densities of ND filters, can drastically modify the issue.
For nigh professional photographers, or for landscape photography enthusiasts, the use of ND filters (together with GND, Graduated Neutral Density, and polariser) is considered fundamental during shooting. The issue obtained is incredibly satisfying and allows us to obtain the best possible RAW file to develop in post-product.
Examples of photos taken with different densities of ND filters are shown below
The photo on the left was taken with an ND half dozen end, in improver to a GND three Stop Hard and the polariser. On the right, however, the six Stop has been replaced by a x Cease.
The movement of the clouds is moderate in the left photo (half-dozen stops) while it is very prominent on the right. In addition, the water is too much smoother and silkier in the right photo. The light is constantly moving, especially during the days with low clouds, a slightly shorter shot like the one on the left allowed u.s. to capture a moment of more intense calorie-free. Instead, in the photograph on the correct with several minutes of exposure, there was a general balance of exposure. This is due to the passage of a deject blocking low-cal during part of the exposure time.
Despite nosotros tried to recreate ii similar shots in post-production, information technology is evident that merely changing the ND filter from 6 to ten stops has immune us to obtain a very dissimilar shot. Without having switched the GND filter or adjusting the Polariser.
In this shot, we take a situation like to the previous one: ND64 vi Cease filter on the left and ND1000 10 stop on the right.
With the 6 End the clouds are more divers, the calorie-free on the water creates accentuated contrasts and the foam on the ocean is clearly visible. Increasing the exposure time to compensate for the use of the 10 Stop we obtain a long motility effect in the clouds, the light is softer and the sea is filled with soft trails that guide the eye. Two different shots, with their characteristics, created by two different ND filters: six and 10 stops.

In this shot we actually run into how much the shutter speed can change a photo: apart from beingness photos taken a few minutes apart, the but real difference is given past the ND16 or ND256. The photographer chooses how long to expose and therefore what issue he gets. In the case of "long exposure" simulated by software, the result would have been completely different, especially on the waves and in general information technology would not have been possible to obtain such quality. The first shot, on the left, was exposed for a few seconds, impossible to obtain such an effect in post-production by blending some photos, nosotros would have a pronounced ghosting issue and many artefacts. Photographic filters give y'all the liberty and joy of shooting, freeing your creativity.

The backlight, reduced past the clouds, has been expertly counterbalanced with a 3-cease GND Hard filter, which has allowed us to capture the wide dynamic range (notice out more than about dynamic range). On the right, all the same, the employ of a 10 stop has created gradual pastel colours, the filter has completely inverse the photo.

What ND filter to choose for mural photography?
Almost probable, looking at the shots above, it seems useful to go all intensities of ND filters. Although it is the most obvious answer, we try to give you a less expensive solution:
For those starting with long exposure it is very likely that beginning with ane filter is a practiced idea. If yous often shoot at sunset or sunrise, with low sun or fifty-fifty beneath the horizon, we recommend starting with a vi terminate or the classic ten stop.
Once you become more expert, 2 or iii ND filters are very likely to be the intermediate choice for many people. If yous want to try shutter speeds closer to 1 or 2 seconds (for effects such every bit those on the last two photos on the left in a higher place), calculation a 3 stop to your kit is ideal. Or if you already accept a 6 cease and instead of making shorter exposures you want to make them longer, it is time to add the ten stop. After all, the ND "Kit" par excellence is made upwards of 3-6-10 Stops.
The eight Terminate is amongst the most popular ND filters, thanks to the fact that information technology allows long exposure times, around the minute with depression dominicus, which is an ideal shooting time for many photographers. In our wide range, you will too find the fifteen stop filter which is very popular as it allows you lot to have incredibly long exposures at whatsoever fourth dimension of day. For this reason, some photographers become the "extended kit", i.e formed of 3-half-dozen-eight-ten-fifteen Stop ND filters. Either manner and whichever road y'all take, nosotros take the products you demand.
Notation: All the shots shown in this commodity are by Alessio Putzu, who kindly gave us permission to use them. In all the shots were used ND NiSi filters, GND NiSi and the Landscape Polariser included in the V6 Filter Holder Kit. The photos are intended to demonstrate the difference between the use of a filter of a sure density compared to another. All photos take been mail service-produced by the photographer at different times and with his personal manner, therefore they should non be considered equally laboratory tests regarding dominant colour or chromatic aberrations, defects of which NiSi filters are famous for beingness free from.
Save upwardly to over 30% with ND Filter Kits
NiSi offers ND filter kits that let you to save from a minimum of x% up to 30% on the purchase of two-three-4 filter kits. Included in all kits are the soft instance for 4 filters, four replacement gaskets, a cleaning textile and a guide to using the filters.
