Is variable ND filter worth it?
If you shoot videos, a variable ND filter is advantageous to keep shutter speeds slow and constant, which can be hard to achieve in light that is bright but constantly changing. It’s also useful when trying to achieve both high image quality and shallow depth of field in environments where the light is a bit bright.
How do you calculate ND?
To make the calculation fast and easy for a 10-stop ND filter in the field, you can adjust the aperture and ISO setting to make the base shutter speed an easy number, say 1/10 seconds (1/10 x 1000 = 100 seconds for 10-stop ND) or 1/20 seconds (1/20 x 1000 = 50 seconds for 10-stop ND), to speed up the mental calculation …
What is the best ND filter for landscape photography?
The most common solid ND filters used in landscape photography are the 3-stop, 6-stop and 10-stop. A 3-stop ND filter is often used to create a realistic sense of motion, while the 6-stop and 10-stop filters may be used for longer exposures from 30 seconds to several minutes.

How well do Variable ND filters work?
A variable ND lens filter is very flexible as it lets you alter light exposure between around 1 f-stop (ND2) and 10 f-stops (ND1000) simply by rotating the outer element of the filter. And it does this without affecting the colour or quality of your images.
Is a variable ND filter a polarizer?
No, variable ND filters do not produce a polarizing effect. While variable ND filters are constructed using polarizers, they do not actually work as polarizers. If you need a polarization effect, you must use a true polarizing filter. But if you want to simply reduce light levels, then an ND filter is the way to go.
What is a 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.
