That's splendid Nat, that's just right let your shoulders relax
there we go, cool. That's a lovely picture of Natasha, she's standing in great light
there's a lovely background and everything else
but it's completely spoiled because it's not sharp its fuzzy
the most people think fuzzy pictures because the shot is out of focus
nine times out of ten if you have a fuzzy shot is actually due to something
called camera shake
the longer the lens you're using the worse the affect can be.
let me show you what I mean. I have here an extremely expensive
no expense spared camera shake demonstrating tool.
If I hold this stick out like that, put my finger
just here and move the stick up and down only about an inch
where my finger is, look at the leaves at the end
their bobbing up and down probably two or three times that amount
that's what happens as you look down your lens the longer your lenses
the more it magnifies this wobbling up and down thing, the distance between me
and Tash is probably going
I don't know, four times as much if you zoomed out right across to the other side of the
park
it'll be even more stuff will be leaping around all over the place
me show you what that looks like through a camera, Jayne's gonna
pop her camera of the tripod, i'm just gonna wander over here and
join Tash whilst she does that
Now, here we go. If I stand here withy Tash
with the lens short at a short focal length
this little discernible movement in the picture is there but if Jenny zooms out
in a makes the lens longer
to get a nice head and shoulders portrayed tight shot lovely
hit you notice there a little bit sad movement
which 100 jiggling around in the frame just a tiny bit
and those tiny movement what will cost camera shake because they'll blood and
you'll get a fuzzy picture
now the obvious thing to do
is what Jay need us most of the time anyway and that issues
a good sturdy tripod what's a good study cuz wobbly tripod useless he won't
freeze camera shake if you have a wobbly cheap tripod
spend the money in the pub instead it will be much better value Tash
here we go excellent Top Model
here we go nice if I take the same shot on the tripod
now it's nice in shock because there's no movement at the camera
and obviously there's little or no movement at lapd but what if you haven't
got
a tripod with you there is another white
what you have to do issues a fast enough shutter speed
to freeze that motion just like you're photographing
someone running a bicycle you could use a far shutter speed to freeze the
movement
now since I put the truck pulled down lights changed a bit
his hey do it as I frame-up the shot of cash
but day looking through the viewfinder I can read of what the shutter speed H
and in this case it's now nineteen after the second but my focal length:
is a 150 millimetres to I need to use
a shutter speed faster than 150 if the second
in order to freeze that motion this little roll
if you're focal length is two hundred male you need a $200 for the second if
it's a hundred million eight hundred for the second
or foster it doesn't matter if you're a hundred million Asian you gotta
thousand for the second because that's way for a faster it will absolutely
freezing you to movement you have when you
juggle the camera around but if you're 200 mail
and even got a twenty-fifth have a second or something like that I pretty
much guarantee you
if you I'm gonna try call you gonna get a blurry fuzzy picture
and having nothing to do with focus it'll be camera shake
okay let's go through what we have to do about this
taken at reich
looking through the camera and you have to do it through the camera to make sure
that it is actually taken like reading of your subject 90 for the second
150 milan's I need more than 150 a
I'm already on the widest aperture the I can use
so I can't get any more light into the camera that way but I can
increase the eyesight because as I increase the I so setting
I'm increasing the sensitivity of the chip in the back of the camera
if the chip is sensitive it doesn't need anything like so much light
I'm going up to 400 ISO from 200
here we go us what to hit that side a bit too so that it's a different picture
now course got somebody walking right behind cash are just gonna
polls for a moment to let go on we go
excellent right my shutter speed is now a hundred and
eightieth a second it gone from
sixtieth 280 a
let's just recap on that for a moment I started off for the ninety for the
second shutter speed
which is too slow to freeze the mobile the movement that the camera shake
bike doubling the I so sensitivity from 200 to 400 I sighed
that had the effect a doubling the shutter speed
from ninety 200 eightieth a second
because my lens was at a 150 millimetres
and a hundred and eighty through the second is a foster shutter speed
the number 150 which is the focal length of the lens
that's fast enough to freeze any motion I may have
when I took that shot think about it just won't happen again in your car to
get your head around it
now another thing you can do to help minimize camera shake
is the way you hold your camera if you hold your camera
like this in two hands and looking like that you'll probably find is really a
little wobbly I know I'm exaggerating now but
it's nothing nothing like as easy as just making a little
rest with a hand and kinda a tripod against your body
and kinda but that you can still was a hermit and turn around and all that
kinda stuff
but it just hold the camera an awful lot stadia and finally of fun breathing
makes an enormous difference
I know it sounds silly but you could Olympic rifle shooting champions
they they really concentrate on their breathing and this is what you doing its
white school shooting a picture
iPhone if I shoot all squeeze the shutter button
on the exhale it works in of a lot better
so I just kind of like brief rest it and then
and click here I can usually get and even steady a picture
hope that helps you should have let me show pics from now on in
