Using Neutral Density Filters In Photography
Using Neutral Density Filters In Photography – I am sure there has been a time when you were surprised after seeing a picture of the sky or a river that is smooth and silky. You may have learned that this is a trick that requires using a slower shutter speed but after a few back and forth, your photos don’t look like the ones you saw.
The truth about this technique is that it requires the use of a dark filter that is placed in front of the camera lens. This is known as a
Using Neutral Density Filters In Photography
Read on and learn why many neutral filters will improve your image and how you can start taking advantage of them quickly.
Nd Filter Photography
Neutral Density Filter, also known as ND Filter, is a piece of dark glass that is attached to the lens to reduce the amount of light that reaches the camera sensor. This means that it takes a long time for the image to appear correctly, so using a fast shutter speed is necessary.
You can compare this to a photo in a dark room compared to a well-lit one; the former requires a faster shutter speed (or higher ISO) to capture as much detail as you would in a well-lit room.
Landscape photographers use this technique to blur moving objects in the frame, such as the water in the image below:

Let’s take the example of different light rooms and translate this into a situation that is more suitable for a photographer where you are taking a waterfall and want to blur the water:
You may find that a shutter speed of 1/500 of a second gives you a well-exposed photo when shooting during the day. However, this is too fast to cloud the water even a little; you need an exposure time of up to several seconds to do this.
Using a narrower aperture, such as f/22, allows you to slow down the shutter speed slightly but the result is a loss in image quality. If it’s still bright outside, this small adjustment won’t extend the exposure time to create a nice blur anyway.
Vnd Vs. Traditional Neutral Density Filters
Since the filter reduces the amount of light entering the camera, you are forced to use a faster shutter speed. Exactly how long the shutter speed can be depends on the filter you are using; it can be anywhere from a second to several minutes.

It can be quite difficult to know what kind of Neutral Density Filter to buy if you don’t look much into them yet; there are plenty of products, systems, settings and even types of filters.
The first alternative is the Screw-In round filters which, as the name suggests, are screwed into the front part of the lens. This type of filter is very common and is the only option you will find at a large electronics store.

Filters are known to let less light slip through the lens than square filters, making it easier to calculate the correct exposure. Personally, I don’t find this to be a big problem as I add this factor into the equation to find the correct shutter speed.
Another advantage of this system is that it takes up less space and is lighter in weight. This can be an important item for those who do long trips or prefer to have a light camera bag.
Also, there are disadvantages to the filter system, the biggest one being the problems of using multiple filters at the same time, which is known as
Cokin’s Not So Neutral Density Filter
. Applying multiple filters at the same time is very common but if you do it with this filter system you get unwanted marks around the image. This is due to the outer edges of the filters that appear in the image as they enlarge the lens by a centimeter or two.
It is not very difficult to remove a vignette in a photo editor like Adobe Lightroom or Photoshop, but you know, the more filters you use, the harder it is!
Remember that filters are not expandable and this means that you may need to buy different ones for different lenses. Alternatively, you can buy an adapter but make sure the filter is big enough to fit a lens of the same diameter.

The square filter system is a bit more advanced than the screw and requires a few extra tools to properly mount it to the camera.
Unlike the previous system where the filter is screwed directly onto the lens, the adapter is the first piece included with this square version. The filter holder is mounted on the adapter and this is where you will insert the filters.
The main advantage of using a square filter system is that it keeps many slots where the filters can be placed. In other words, it is possible to use multiple filters at the same time without seeing any unwanted vignetting. Some wide angle lenses may have a little vignetting with some markings but it should be the same if you use one or three filters.
How To Use A Neutral Density Filter
You will also find that this system is more flexible to use as you can rotate the filter and slide the filter up and down in the slots to suit the specific scene you are photographing. This is especially important when using Neutral Density filters.
Now, this system is bigger than the filters and you will notice a big difference in size and weight. Although higher quality options tend to be more robust, square filters are also known to be somewhat weaker.
Keep in mind that there are big differences between both brands when it comes to the quality of the filters and holders, as well as their design. For example, in the NiSi V6 Pro model, you can place the Circular Polarizer in the filter holder but for other models, you may need an additional adapter.

Most filters include adapters of different sizes but this can vary between brands. I recommend double-checking what’s included to make sure you have the correct adapter size for your lens.
I’ll tell you the truth right now: there is no such thing as a perfect plan for everyone. This depends a lot on your preferences and budget. It took me years to find the right system for me but my needs have changed in that time.
There are three main factors to consider when looking for the best Filter System:
Why You Need Filters In Landscape Photography
The area of use is perhaps the most important question when choosing between a filter system or squares. If you are someone who spends a lot of time traveling and have a heavy backpack with limited space, a backpack may be more convenient. Those who don’t rely on weight savings can appreciate the added flexibility the square filter system offers.
A Square Filter System is used to have both a circular polarizer and a 10 Stop ND Filter at the same time. Note that there is no vignetting.
If you’ve never installed filters and don’t intend to use High Definition Filters, the screw-on option is the best alternative. Additional filter holders, adapters, bags and filters seem a little excessive if you are only using one Density Filter at a time.

However, if you intend to use a Dimensional Filter or perhaps a Polarizer and a High Frequency Filter at the same time, the square filter is ideal.
The cost of purchasing a new filter and/or filtration system varies greatly depending on the choice of brand, quality and system.
Square filters are usually more expensive and you will need a filter holder and adapter. This means that the initial investment is higher if you are going to buy one or two screw pins.

Therefore, filters from most manufacturers come in different filter holders so it is possible to choose a budget filter and the best filter (although I recommend sticking to the same for both retainer and filters).
I’ve found that a cheap alternative from any local electronics store is the right place to start. These are far from the best filters out there but they are great in the beginning when you are learning how to use them.
The first Neutral Density filter is an inexpensive filter found at your local electronics store. The price is about $20. As a beginner photographer these where the best filters to start; they allowed me to use the shutter speed a little bit but perhaps more importantly they helped me understand the relationship between the important camera settings.

I used these filters for a while before I realized that I needed a darker filter that would allow for faster shutter speeds. This was before square filters were as popular as they are today so I ended up buying B + W screw filters.
These are much more expensive but the quality is also better. However, B+W filters at the time were known for their bright red color, which I honestly didn’t care for at the time. Having a dark filter and getting to the shutter speed to a few minutes makes it worth it.
It took about a year until I switched to a square filter
