There are two basic things you require when calculating exposure times using ND filters and they are the base exposure time calculated by a meter reading without ND filters on the lens + the density and type of filters you will be using to take the exposure. Most people are still practicing trial-and-error to obtain the perfect exposure in night photography. In failing light a 10 stop ND filter will require a serious time commitment. For my eBook, latest images, photography tips, news and events. The “1-second exposure” technique can also be used with a 6-stop ND filter in low-light conditions when it is impossible to estimate the exposure with camera metering, especially the resulting exposure time is more than 30 seconds for most cameras. After going through all the apps and reading reviews I bought Long Exposure Calculator. Adjust the exposure time to 2 seconds at ISO-6400, which correspond to 2 minutes at ISO-100; 3 seconds correspond to 3 minutes; so on and so forth. Similarly, to simplify the calculation, we assume that 2 6 is equal to 60 instead of 64. To simplify the calculation, we always assume that 2 10 is equal to 1000 instead of 1024 since it … 4. The countdown timer is convenient for many camera brands without a timer when using the bulb exposure mode.

It also lets you set your filters by ND1024 or ND 3.0 methods, chose light or dark background, and gives hints on how to shoot long exposures. Exposure Calculator (ND Filters): Amazon.fr: Appstore pour Android. ‎Long Exposure Calculator is a utility that helps you determine the correct exposure time/shutter speed when using Neutral Density filters. In this video above, I introduce and explain how to use my Exposure Chart for ND Filters. First, take a test shot by setting your camera to M mode (manual mode), ISO-6400, 1 second (Image 2a). The discrepancy can compound at long exposure times and lead to inaccurate exposures when using formulas/calculators. First check the base shutter speed (without filter) in the first row, then go all the way down to the intersection with the column of ND filter, and this is your final shutter speed. Therefore, 60x increase in exposure time compensate 60x decrease in ISO sensitivity. It is a common that most people trying to guess the exposure time when using these high strength ND filters, like 10-stops ND filters. This is significantly noticeable when you are making extremely long exposure, let’s said 5 minutes or longer. If yes, follow by setting your camera to B mode (bulb mode), ISO-100, 1 minute, with the same aperture used in the test shot (Image 2b). And as you continue to do trial-and-error by adjusting the exposure, eventually the light is gone before you figure out the perfect exposure! You can even use the “1-second exposure” technique in night photography when no ND filter is used. What if the test shot of 1 second is under-exposed? Example: Yes, I would like to receive emails from Kah-Wai Lin Photography. ND filter manufacturers use three different methods for designating how dark a filter is, but this app only uses ND numbers, like ND32 or ND1000. Use the NiSi Filters app to calculate the exposure time when using NiSi ND filters. Have you ever seen long exposure images shot using 10-stop ND filters? For a 6-stop ND filter, if the base shutter speed (without filter) is 2 seconds, with the use of a 6-stop ND filter, the exposure time becomes 2 x 26 = 2 x 60 = 120 seconds. You can easily play around with ISO or aperture. The screenshot shows the parameters for a test shot with ISO 1600, aperture f/5.6 and a shutter speed of 1/500s. If you are particularly interested in the math of how I arrived at these exposure times, you should check out my other article : How To Calculate Long Exposure Times.

For 10-stops ND filter, if the base shutter speed (without filter) is ¼ seconds, with the use of 10-stops ND filter, the exposure time becomes ¼ x 2 10 = ¼ x 1000 = 250 seconds. Then, increase the ISO until the camera metering shows that the shot is well exposed (EV 0) and count the number of stops increased in ISO. For example, the shot with 30 seconds is well exposed at ISO-1600, which is 4-stops increased from ISO-100 (1600 > 800 > 400 > 200 >100). For example, if the exposure time is 10 minutes at ISO-100, you can decrease the exposure to 5 minutes at ISO-200 or 2.5 minutes at ISO-400; if the exposure time is 10 min at f/16, you can decrease the exposure to 5 minutes at f/11, or 2.5 min at f/8. Filters of a greater density, however, will prevent you from seeing anything through the viewfinder, so you’ll have to focus and calculate your exposure before you fit into position. You can even use “1 sec exposure” technique in night photography when no ND filter is used. 6-stops decrement results in 26 = 64 times decrease in exposure. Therefore, the final shutter speed is a 4 stop increment of 30 seconds (30s > 1m > 2m > 4m > 8m) which is 8 minutes at ISO 100. If the target exposure time is over the limit your camera will calculate, you can use an app to help. To mention but a few, NiSi Filters, Long Exposure Calculator, LongShot, Exposure-Calculator, Neutral Density Calculator, Slower Shutter Exposure Calculator, etc. There are plenty of exposure calculator applications available for both Apple and Android, and most of them are free to download.
