the amount of light that is let through the lens therefore you can lengthen your
shutter speeds if you like getting wispy clouds dreamy water escapes or smooth
waterfalls this is the filter to use it can also be used to get rid of people
and cars if you extend the exposure long enough and the 10 stop ND filter is
strong enough so you can get some really long exposures even in the middle of the
day a good neutral density filter won't give
you any kind of color casts and it'll be even throughout the frame a 10 stop ND
filter can also be called an ND 1000 or an md 3.0 the nd1000 is just the name
that it's been given the nd 3.0 refers to the optical density so these
three different names refer to exactly the same filter when you buy a really
cheap filter you'll notice that it gives a color cast to your images so you need
to spend a little bit of money and get a good quality ND filter I have bought a
Tiffin 77 millimeter ten stop ND filter I then have step-up rings so it can fit
this to any of the lenses that I have my largest lens is a 77 millimeter so I
don't need anything bigger than that and that's what I suggest you to find out
which lens has the biggest filter thread size and then buy the one for that and
then buy a whole series of step-up rings this will mean you'll only have to buy
one filter I take my set of filters wherever I go today we're just talking
about the 10 stop ND filter but I also have a four stop and a three stop and
this tends to give me everything that I need as well as the ND filters I do have
graduated filters but this is a subject for another video to keep them safe I
store them in one of these pouches this lessens the chance of them getting
scratched or getting dirty a 10 stop ND filter is a really dark filter as the
name suggests it drops it by 10 stops of light so this means if you're taking a
shot at one one-thousandth of a second normally when you put the filter on
you'll be able to drop your shutter speed to one second obviously with this
large drop-in exposure you'll need to be shooting with the tripod and
really long exposures you'll need a remote shutter release if it's windy
it's good to anchor down the tripod with your bag or a bag of stones and make
sure your camera strap is tied up or if you can take it off the camera you'll
also need an ND conversion table this basically gives you your current shutter
speed without the filter and then also it will give you the shutter speeds for
lots of different filters it's worth having they're saved on your phone or
having one of them printed out in your camera bag all you need to do is search
for an ND conversion chart on Google or any other search engine once you've
found a composition you like put your camera on a tripod frame up the shot
switch to manual mode and change your settings so you get a good base exposure
without the filter attached if you're unsure about shooting in manual mode all
you need to do is take a photograph in the automatic mode or one of the
semi-automatic modes then just remember the settings and then put those settings
in once you've switched it to manual mode then you'll get exactly the same
exposure if you want to learn more about aperture priority mode click on the I in
the corner or the link in the description you need to be in manual
mode so the camera doesn't start guessing what the exposure might be once
you attach the filter today I started with a shutter speed of 1 250th of a
second an aperture of f9 the ISO at 80 with a 25 millimeter lens on a Sony a7
t3 it is in the afternoon and the Sun is still bright but I just want to show you
how I can shoot long exposures in the daytime with this filter next set your
focus and then switch to manual focus this is so the focus doesn't hunt around
when you put the filter on attach the filter as I said before my filter is 77
millimeters and I have a step-up ring from 67 to 77 next you need to drop your
settings to accommodate for the filter I'm shooting up 1 250th of a second so
I'll drop my shutter speed to 4 seconds lastly I'll put it on to self timer and
set it to seconds and then I'll take a shot
this is without the filter and this is with the filter as you can see it
smoothes out the water and if the clouds are moving fast enough it starts to blur
them any objects that are moving will also be blurred like these boats with
this filter you can manipulate your aperture to change the shutter speed so
as you close the aperture down you can lengthen your shutter speed as you open
the aperture up you can shorten your shutter speed if the objects are moving
fast enough they can disappear especially if they are a similar color
to the background in this shot people were walking along the paths but with a
20 second exposure there was a person close to the camera that disappeared
completely further away the people become blurs or smudges so just keep an
eye on this as they can start to look a little strange also if they stop for a
while during your exposure they can start to look at little like ghosts with
water if the exposure is too long it will smooth out completely so you might
have to experiment with different shutter speeds the waves were tiny where
I was so I couldn't get any decent lines in the foreground
sometimes when the waves are bigger you can get really great leading lines as
the water draws away from the camera so again this is just about experimenting
with your camera with your shutter speeds and with the timing of the waves
with this last image the water was quite a lot darker than the boat so the white
boat left a streak in the shot I'll normally use my 10 stop ND filter when
I'm taking photos of seascapes rivers or waterfalls but I always have it in my
bag ready to go show you when I'm hiking if I come across a waterfall or a
seascape that I really like and I want to slow the shutter speed down I have
the ability to do so as the light drops towards the end of the day you might
find that your exposures become really long this is when you'll have to switch
it to bulb mode and use a shutter release cable at this point what I tend
to do is start attaching my weaker filters to keep a similar exposure as
the light drops you can use the 10 stop ND filter but you'll find that your
exposures will get longer and longer if you are keeping on
shooting really long exposures you've got to decide whether you keep your long
exposure noise reduction on or off I have done a video on this already so
click on the I in the corner or a link in the description to that video if
you're not sure about long exposure noise reduction when it gets dark you'll
probably want to remove the 10 stop ND filter this is almost too dark to take
shots at night unless you're doing extremely long exposures I've also got a
few tips when you are shooting with a 10 stop ND filter to get better photographs
you should make sure your filters are clean I clean them and the front element
before attaching the filter every single time keep them safe in one of these
patches so they don't get scratched or they don't get dirty always have an ND
chart saved in your phone so you can work out quickly what the exposure will
be otherwise you'll have to count in clicks to get the right settings I've
set my camera to 1/3 increment stops so therefore when I'm reducing the shutter
speed I know that if I click that dial three times I'll get a reduction of one
stop of light so when I click it 30 times that'll reduce the light by 10
stops it does take ages to do it this way though so that's why it's good to
have an ND chart with you if you're shooting with that DSLR and you have an
image stabilized lens turn the image stabilization off this is because the
stabilization system in the lens tends to expect movement but because there
isn't any it'll sometimes jitter around giving you a softer image if you shoot
with the Sony's that have embody image stabilization these tend not to be
affected by that so I think the computer inside the camera realizes that it's on
a tripod and stops moving the sensor about so with a Sony you can have Ibis
on or off for some of the other brands I haven't shot with any of them so you'll
have to test this out for yourself if you're not sure just turn off image
