have you ever wondered how people are able to freeze motion in the images or are able
to capture long exposures like they are able to capture star trails or car trails and you
want to learn them you are in a right place so hey guys I am Saurav and I am back with
the second video of the series where I talk about stuffs related to photography. The first
video was about Aperture where I explained you what Aperture is and how it should be
changed according to the change in situation. I am going to do the same in this video but
this video will be dedicated to Shutter Speed. So let us understand what Shutter Speed is,
to understand that first let us understand what is actually Shutter. So imagine your
camera sensor as your Human Eye, so the shutter is actually the eye lid so once the eye lid
is closed the shutter is closed. So basically once your camera isn't fired, once your camera
is ideal, the shutter is closed, so that no light can come in and hit the camera sensor,
when you press the shutter button what exactly happens is your shutter is opened so that
the light is allowed to come and hit the camera sensor and once sensor is done collecting
all the light and collecting all the information it needs the shutter closes and that is how
the image is captured. So what is shutter speed ? Shutter Speed is actually the amount
of time that your shutter is open. Basically the amount of time for which the light can
come in and hit the camera sensor. So by adjusting the shutter speed you're actually adjusting
the amount of time for which your shutter is open. Shutter speed is expressed in seconds,
mostly in fraction of seconds. Like if you have heard of 1/2 of a second of shutter speed
it means you take one second, you make two pieces of it and you're using only one piece
out of it. So you're using only half second, now imagine the shutter speed is 1/100th of
a second it means that you take 1 second, you make 100 equal pieces of it and you're
using only one piece that is 1/100th of a second, so if the denominator is greater the
shutter speed is faster. Now, for example 1/4000th of a second is greater than 1/2000th
of a second by greater I mean faster. so 1/2000th of a second is faster than 1/100th of a second
and so on. So this is one side of shutter speed the second side is where the shutter
speed is 10 seconds where the camera is exposed for ten seconds to the scene. So don't be
confused between 1/10th of a second and 10 seconds. 1/10th of a second is actually 1/10th
part of a second and 10 second is complete 10 seconds where the camera is exposed for
complete 10 seconds so the exposure can be, the shutter speed*can be 10 seconds, 20 seconds,
30 seconds or more where the shutter is open for the longer duration of time. So now I
will show you how by changing shutter speed we can freeze the motion like this or we can
capture long star trails or car trails in a nutshell long exposure photography like
this. So now our basic objective is to freeze the motion so that's why what we're going
to do is we're going to use a faster shutter speed. If you're using shutter speed like
1/100th of a second or 1/200th of a second it's not going to work because the water is
going to be out of shape pretty soon. So you have to use a very fast shutter speed. As
i said in the video before anything like 1/2000th of a second or 1/4000th of a second is going
to be appropriate for the situation. Now when you do this kind of photography it might not
be
perfect at the first time.
You have to practice couple of times, 10 times maybe even 20 times and then you will get
a perfect shot. So now, without further-a-do lets start getting that shot. So we tried
to shooting some of the shots where we tried to freeze the motion, we try to freeze the
water but here you have to remember one thing while trying such experiments every time you
won't get perfect shots. Like you can see this couple of shots, they're good shots but
they're not perfect. The shape isn't intact, so you have to practice a little bit till
you start getting closer to perfect shots. So now you can see in the background their
are lots of cars coming by and since the light is very less I am using a mobile flash light
so you can see me, in real it's very dark so it's a proper situation where we can set
our exposure, where we can set our shutter speed* to 20 seconds or 30 seconds and get
a good car trail shot. So for car trails or long exposure you have to make sure you don't
have much light in the scene, because since the light is going to hit the camera sensor
for such huge amount of time, for 20 seconds, you need less light so after 20 seconds you
get a good exposure. So now lets start shooting some car trails and see what results
do
we get.
So when you are taking images you will notice that some of your images are way too darker
than you would expect or some of your images are way too bright. So this is where practice
comes into play, you have to start practicing and experimenting with shutter speed settings
so that you get an image which you had in mind. You have to practice a lot if you have
to master the technique of shutter speed. So for this particular shot actually I have
combined two different images, they're of actually same location but they're two different
images. One image is actually of the car trail which I showed you right now where I kept
my shutter speed around 20 seconds or 30 seconds I guess it was 20 seconds and the second shot
is of actually a star trails where you can see the path of the stars are captured where
I exposed my camera for 1 and half hour. So you can try experimenting with shutter speed
and get certain cool effects like this. So i hope you enjoyed the video guys. This video
was about shutter speed, my next video will be about ISO. So if you like the video hit

are released you can watch them. If your friends are interested in photography make sure you
share it with them. So, I will talk to you guys in the next one. Have a great day, BYE
