During sunset, the light is getting dimmer, and there might be a risk of getting an under-exposed image. Calculating a stop of light variation in shutter speed is a simple … Calculating your base exposure time will need to be done without any neutral density filters, although can be done with a circular polarizer attached to your lens. To simplify the calculation, we always assume that 2 10 is equal to 1000 instead of 1024 since it is negligibly small. Similarly, to simplify the calculation, we assume that 26 is equal to 60 instead of 64. A very important consideration when doing long exposure photography is the change of light, especially during sunrise and sunset when the light changes very quickly over a short period of time. Here is an ND calculator chart for 6 stop, 10 stop and 15 stop ND filters. Use a 16 stop ND Filter to Make People & Cars DISAPPEAR!! As for 6-stops ND filter, you may require to calculate the exposure time under low light condition when the camera metering is no longer capable to estimate the shutter speed especially it is over 30 seconds for most camera. Most DSLR cameras can calculate exposure times up to 30 seconds and some mirrorless cameras up to 60 mins with an ND. As for a 6-stop ND filter, you may need to calculate the exposure time under low-light conditions when the camera metering is no longer capable of estimating the shutter speed (especially if it is over 30 seconds for most cameras). 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. It is also possible to add up to 3 ND filters of up to 30 stops each to the calculations, handy for those long exposure photographs to blur water and clouds. 6-stops decrement results in 26 = 64 times decrease in exposure. Features: - Very simple to use - Includes a countdown timer if the exposure time is 10 seconds or longer.

Sometime, the simple math will do the job very well! Bonjour, Identifiez-vous. Here’s the formula to calculate final shutter speed: 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. They are visually energetic and dynamic, due to the motion blur caused by the moving clouds over long duration of exposure. In this video above, I introduce and explain how to use my Exposure Chart for ND Filters. Finally enter the stops of light that your ND filter actually subtracts, the actual density (ND 3.0 10 stops). Adjust the exposure time to 0.5 seconds at ISO 6400, which corresponds to 0.5 minutes at ISO 100. Given an exposure (Aperture, Shutter speed, ISO), allows calculating equivalent exposures - set 2 new parameters (a combination of Aperture, Shutter and ISO) and the 3rd parameter is automatically calculated. In other words, if you are out with a bunch of friends and you are all playing with different ND Filter configs, the app can be used to calculate the correct exposure for each person there, an alarm can be set for “Frank need to close shutter now”, “Jeremy close shutter now” etc. Finally, set the camera to B (bulb) exposure mode, increase the shutter speed to compensate the stops different in ISO. Download this chart here. Remember, though, that the exposure numbers given are an indication and you should always check your exposure. 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.

Neutral Density Filters – Long Exposure and Calculating Shutter Speeds. Adjust the exposure time to 2 seconds at ISO 6400, which corresponds to 2 minutes at ISO 100; 3 seconds correspond to 3 minutes; so on and so forth. Now choose the desired ND filter and change the other exposure parameters to fit your needs for the final shot. 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. On the other hand, 1 minute is 60 times longer than 1 second. You can use the table above or compile your own exposure calculation table based on the formula in the above section (or download the chart online by simply searching “long exposure calculation table” or “long exposure calculation chart”). To make the calculation fast and easy for 10-stops ND filter in the field, you can adjust the aperture and ISO setting to make the base shutter speed an easy number, let’s said 1/10 seconds (1/10 x 1000 = 100 seconds for 10-stops ND) or 1/20 seconds (1/20 x 1000 = 50 seconds for 10-stops ND), to speed up the calculation in mind. In failing light a 10 stop ND filter will require a serious time commitment. Features: - Very simple to use - Includes a countdown timer if the exposure time is 10 seconds or longer.

This enables us to lengthen shutter speeds to create movement in the sky, sea or subject. 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. To simplify the calculation, we always assume that 210 is equal to 1000 instead of 1024 since it is negligibly small. Supports calculation of EV, ND Filter values and Long Exposure up to 32 minutes!
