Simple Math. For a 10-stop ND filter, if the base shutter speed (without filter) is ¼ seconds, with the use of 10-stop ND filter, the exposure time becomes ¼ x 210 = ¼ x 1000 = 250 seconds. To simplify the calculation, we always assume that 210 is equal to 1000 instead of 1024 since the difference is negligibly small..
How many stops is ND 32?

How many stops is ND 512?
Understanding Neutral Density Filter Names and Numbers
| F-Stop Reduction | Optical Density | Filter Factor |
|---|---|---|
| 7 | 2.1 | 128 |
| 8 | 2.4 | 256 |
| 9 | 2.7 | 512 |
| 10 | 3.0 | 1024 (sometimes called ND1000) |
How many stops is ND 256?
8 F-STOP REDUCTION | Gobe Neutral Density ND256 provides a fixed 8 f-stop light reduction, which allows long exposure and motion blur techniques in bright light.
How many stops is ND 16?
An ND16 filter can reduce 4 stops of light, allowing you to slow the shutter speed from 1/400s to 1/25s.
What is a 4 stop ND filter?
An ND filter of 4 is going to let in 1/4 amount of light and so on. So if it’s a 3 stops reduction it’s going to let in 1/8. if it’s a four-stop reduction so it’s an ND 16 it’s going to let in 1/16. if it’s an ND filter then reduce it by 5 stops that would be an nd 32 .
When would you use a neutral density filter for video?
Used to control shutter speed, neutral density filters allow the use of wide apertures like f/2.8 in bright environments, like when shooting under a harsh afternoon sun. By allowing the use of wider apertures, ND filters give videographers more creative control over their exposure parameters, like depth of field.
What ND filter to use on a sunny day?
A 3-stop or 0.9 density ND is ideal for waterfalls in bright sunlight, slowing the exposure to a second or so, depending on the f-stop and ISO used. A strong 10-stop or 3.0 ND filter can blur clouds over several minutes, even on a bright sunny day.
What is the darkest ND filter? If you are a little bit lost, do not worry; all you need to understand is that “darker” ND filters block more light. ND8 is darker, ND2 is less dark. A 0.9 ND Filter is darker and a 0.3 ND filter is less dark. A 3 stop ND filter is darker and a 1 stop ND filter is less dark, and so on and so forth.
When would you use a 10 stop ND filter?
A 10 stop ND filter allows only 1/1000th of the ambient light to reach the sensor and can be used during sunrise, sunset and the brighter parts of the day in between. You can achieve artistic effects like perfectly silky smooth water and streaky clouds.
What is 6 stop ND filter?
A 6-Stop ND Filter allows you to increase the exposure time by six stops (equal to 64 times). In other words, it can make a huge difference, especially when used during hours with low light.
How many stops is ND400?
This ND2-ND400 Blue Multi-Coated Variable ND Filter from K&F Concept is a 52mm variable neutral density filter providing an adjustable light reduction of 1 to 8.6 stops.
Which ND filter is best for sunset?
1. Neutral Density (ND) Filter. These are exceptionally handy for many scenarios, but they’re especially useful for sunrises and sunsets in giving you longer exposure opportunities when the sun is still producing a lot of light and your shutter speed can’t get quite low enough for a really long exposure.
What is f-stop in ND filter?
ND lens filters vary according to how much light they let in, and this is determined by a filter’s f-stop reduction. Essentially, an f-stop relates to the aperture size, ie, how open or closed the aperture of your lens is, for any given photo.
What is a 3-stop ND filter?
How do you focus with a 10 stop ND filter? I set up the shot and then gently slid in the 10 stop filter into my Cokin holder. Then I switched to manual focus and hit the remote shutter release. I can’t get any of my shots to be in focus.
How to focus with a 10 stop ND filter.
| Make | Canon |
|---|---|
| Focal length | 105mm |

Can I stack ND filters?
However, we recommend you avoid stacking any filters with the Variable ND filter range as it can create vignetting. Remember that stacking too many filters together can cause vignetting so we would not recommend stacking more than 2 filters together.
What is a 6 stop ND filter?
Medium Long Exposures: 6-Stop ND Filter
A 6-Stop ND Filter allows you to increase the exposure time by six stops (equal to 64 times). In other words, it can make a huge difference, especially when used during hours with low light.
What order do you stack filters?
No matter how many filters you are using, and which combination of filters you choose to use in a stack, it is very important to fill slot #1 of the filter holders first, and then ensure that any Neutral Density Filters that come with a rubber light seal on them are always inserted into slot #1 first.
Is 8 stop ND filter enough?
The 8 Stop is among the most popular ND filters, thanks to the fact that it allows long exposure times, around the minute with low sun, which is an ideal shooting time for many photographers.
Can you stack ND filters?
However, we recommend you avoid stacking any filters with the Variable ND filter range as it can create vignetting. Remember that stacking too many filters together can cause vignetting so we would not recommend stacking more than 2 filters together.
How many stops is ND1000?
When you first start to experiment with long exposure photography, the 10 stop (ND1000) is the perfect neutral density filter to begin with. A 10 stop ND filter allows only 1/1000th of the ambient light to reach the sensor and can be used during sunrise, sunset and the brighter parts of the day in between.
How many stops is .6 ND filter?
What do the numbers on ND filters mean?
| Stops of Light Reduction (There are filters that are measured to a fraction of a stop, but, for simplicity, we are using whole numbers here with the exception of a few filters.) | Optical Density Number (Sometimes prefaced with an “ND” before the number) |
|---|---|
| 17 | ND 5.1 |
| 18 | ND 5.4 |
| 19 | ND 5.7 |
| 20 | ND 6 |

How many stops is .9 ND filter? The Tiffen Series 9 ND 0.9 Filter is a solid neutral density filter providing a 3-stop exposure. This 0.9 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required.
