Hard
Usually used to shoot the picture when there is obvious boundary between the dark and bright area. Such assea level, skyline after sunset or sunrise, sea of clouds and flowers etc.

Soft
To b a l a n c e t h e l i g h t between sky and ground. Usually used to shoot the picture when the sky is much brighter than the land.

ND Grad. "Grad" is short for graduated neutral-density filter, which is also
known
as
a
gradated
neutral-density filter.
Camera is different from human eye. The light sensitization of human
eye
is
stronger,
so
people can easily see the light and dark areas clearly.
However, the light sensitization of camera is weaker, so it cannot exposure
the
details
of
the
extremely light and dark scenery at the same time. In order to avoid the lost of any detail, people use GND filter to reduce the exposure of the bright part, which can balance the bright and dark part of the scenery.

Classification: 0.3 / 0.6 / 0.9 / 1.2 / 1.5
Corresponding downshifting of exposure: 1 Stop / 2 Stops / 3 Stops / 4 Stops / 5 Stops
Sizes: 70 x 100mm / 100 x 150mm / 150 x 170mm
How to use: To hold by hand or square filter holder, the latter can combine several pieces of square filter at the same time.
How to choose: The main consideration of choosing a GND is: strengths, transitions, sharpness, low colour cast and low reflection. The technique of making the coating used in the production of camera filters plays an important role as it literally affects the performance of the filters. NiSi filters are perfectly created with NiSi HD nano coating in both sides of H-K9L optical glass, which includes water oil resistance coating, remove reflection coating and HD nano coating. Many neutral grads are not neutral as the colour distortion may occur. However, NiSi grads are made in optical glass which are genuinely neutral as they have ultra low colour cast and low reflection. Before you choose your grad filter, you may want to consider the strength and transition of your filters. It depends on what kind of photography you want to capture as different kind of filter gives different result.
Coating:
water oil resistance coating remove reflection coating Nisi HD nano coat waterproof in double sides optical glass
only one layer coating bad transmittance easy scratch
HD nano coating
H-K9L is one of the highest quality optical glass even no bubble great physical chemical performance, in the same standard with German Schott N-BK7 and Japan HOYA BSC7.
resin filter coated by dying color with color cast, bad stability
Transitions: Hard GND
: These have a sharp cut between light and dark.
Soft GND
: They have a gradual change from light to dark.
Reverse GND : These go sharply from clear to dark, and then smoothly back to less dark. These are used for sunsets or sunrise, where you want clear for the foreground, very dark right at the sun at the horizon, and then less dark as the sky goes up above the sun.

First up was a trip to Dovercourt beach on a cloudy afternoon to t r y o u t t h e 3 . 0 N D f i l t e r. H a v i n g settled on a composition I took a shot
without
any
filters
for
reference and in this case the exposure
captured
information
all
with
no
the blown
highlights or blocked shadows so there's
perhaps
an
argument
there for not needing filters at all here
but
lets
be
honest,
the
original image is a little dull.
Fitting the 0.9 soft grad to add a bit of drama to the sky I then checked
my

ND
exposure, filter
exposure
in
and bulb
mode. The filters slot snugly into the holder and the edges of the ND filter have been left clear of the rubber gasket to aid in this, all adding to that quality feel I keep going on about.
Straight out of the camera things w e r e l o o k i n g b e t t e r a l r e a d y, t h e image was slightly underexposed so I'd guesstimate that the filter is slightly over 10 stops but a slight variation is not uncommon with extreme ND filters and my L e e B i g S t o p p e r i s a c t u a l l y 11 stops. There's also a cool colour cast, which is something I'll look at a little closer in the second set of images but it's not something that bothers me especially in this case when the final processed image is mono.

With NiSi 0.9 soft GND & Lee big stopper (10 stop) ND filters no adjustments to show colour cast
I mentioned earlier the colour cast found with the 10 stop filter and the four images below illustrate the nature of that colour cast.
The first image is the test shot without filters (top left) then below that the unedited image with Nisi filters which clearly shows a cool colour cast. In the image next to that (bottom right) I've replaced the Nisi 10 stop filter with a Lee Big Stopper which shows a very similar (but slightly more magenta) colour cast. Although it's worth mentioning here, the cool colour cast isn't an issue f o r s e v e r a l r e a s o n s i n m y o p i n i o n .

Moving on, the image quality with the filters was pretty impressive, images were suitably clear and sharp and I could see no reduction in image quality at all. read more

ND Filters. Neutral Density (ND) filters are designed to reduce the amount of light passing through the lens so that a long exposure is required to record an image or film. In order to achieve this without causing a colour cast they are designed to absorb all the
colours
spectrum
in
in
the
equal
visible
amounts,
which is why they are grey in appearance.
ND
filters
have
two
main
advantages, as you can use a longer exposure to emphasize movement. However, you can also use it to allow use of wider apertures to reduce depth of field.
