The Left Aqua Column is your Standard Non-Filtered Exposure Time.
The Pink Row is your ND Filter Light Reduction in f/stops.
The Table displays your New Shutter Speed with the ND Filter attached.
Shutter Speeds over 30 Seconds (Purple), will require switching to Bulb Mode and using an Intervalometer (Timed Shutter Release).

Example (Shown in Yellow): If you normally shoot at 1/125th of a second (Left Aqua Column) and add a 3 Stop ND8 Filter (Pink Row), your new ND Filter Shutter Speed will be slowed down to 1/15th of a second. Most Digital Cameras can automatically compensate for the addition of ND Filters, and automatically adjust the shutter speed (up to 30 seconds) when you are in Aperture Priority Mode.
