Neutral density filters are a must-have kit for any photographer; they indicate how many stops of light darken the exposure.

The majority of ND filters are labeled with a factor or optical density number. Both of them refer to the amount of light that is lowered by a certain number of stops.

-> ND2, ND4, ND8, and so on refer to the amount of light that is reduced. ND8 cuts the light to one eight, whereas ND2 cuts it in 1/2.

-> Exposure values like 1 stop, 2 stops, 3 stops, and so on are the most convenient because they inform you how many stops your exposure will be adjusted by.

Each stop of exposure value denotes a reduction in light.

1 stop equals ND2, 2 stops equal ND4, 3 stops equals ND8, and 4 stops equals ND16.

The neutral density filter, sometimes known as an ND filter, is a must-have piece of equipment for every landscape photographer. It’s put in front of the lens to cut down on the quantity of light that reaches the camera’s sensors. It’s equivalent to wearing sunglasses over your eyes. ND filters come in a range of strengths ranging from 1 to 10,000.

So, when does this ND filter come into play?

  • When you want the brightness of the sky to be reduced.
  • Video shooting with wide aperture lenses.
  • Shooting on a bright day.
  • Wide aperture on a sunny day.
  • Long exposure images, such as those of a river or waterfall, are popular.
  • In very bright light, a shallower depth of field.
  • Diffractions are being reduced.
  • With moving subjects, blur the motion.

Which ND numbers should I buy?

In terms of fractions, keep in mind.

The amount of light diminished by the ND filter with a strength or intensity of 2 is 1/2, whereas the amount of light diminished by the ND filter with strength or intensity of 4 is 1/4. So, for three stops, it’s 1/8, while ND 16 allows for 1/16, and so on.

Here are a few images to look at.
