i've always fancied having a go at long
exposure movement shots the sort of
thing that combines a long exposure with
blur and the freezing power of flash now
seth miranda right here on adoramatv he
is the king of this type of photography
up close so i thought i'd do something a
little bit wider so in my small home
studio which is 15 feet by 17 feet i've
got this background set up i'm gonna
need every single inch of this to pull
it off i suspect
now i'm gavin hoey and you're watching
adoramatv brought to you by adorama the
camera saw that's got everything for us
photographers and if you haven't already
done so click on the subscribe button
click on the bell icon so you never miss
a video right here on adoramatv because
we have new stuff pretty much every
single day
so let's get the light set let's get a
dancer in
let's get shooting
[Music]
so to make this work there are three
essential things you need and the first
one well let's talk about the background
you need a dark background for this
effect to become really obvious now that
could mean you're going to under expose
the background you could do this with a
white wall if you had enough space
not in my small home studio so instead
i've gone with a physical dark
background
at least the best we can that would be
absolutely fine the next thing is light
source and you're going to need two
types of light for this you're going to
need a flash so i've got my flash here
i've got the explore 400 from flashpoint
and you're going to need some continuous
light so that is up on the other side
and that is the interfit badger beam
it's a 60 watt led continuous light
both of these lights have grids on them
and the grid is there simply to give me
some direction to the light because i
really don't want any light spilling
onto the background as it's not
absolutely brilliantly black so that's
what that's there for so those are the
three essential things but technically
there's four things you need because the
fourth thing you need is a really really
good model and today we're really lucky
because we got the awesome sophie come
on in
sophie is also a dancer so that works
really nicely let's get the light set
and see how this is going to work
the first thing we should sort out is
the lighting because we've got multiple
lights going on here not least the
lights in the room so i'm going to turn
on the badger beam there we go and i'm
going to turn off the rim lights
like that that's good so now we have
light coming down onto sophie but you'll
notice the flash although it has a
modelling light it's really important
that that is turned off however it is
actually on the flash is on ready to go
so i've got my camera set up at the
usual settings flash sync speed i've got
iso 100 f 5.6 let's just take a picture
of sophie see what we get now at those
settings even though the led is on it
can't be recorded by the camera because
it's just under exposing so in order to
see the led i need to increase the
amount of time the shutter is open
so we were at 250th of a second let's
slow it down to maybe a 50th of a second
and try that
so at that setting there is a little bit
of light coming through but it's still
not particularly bright in fact i need
to go down to something more like a
tenth of a second before i can really
see any effect from the led
the flash however is always the same the
flash lasts for a tiny period of time
but the longer the shutters open the
more of the led light i see
but here comes the fun bit if i take my
camera off the tripod
and i do the same shot okay sophie here
we go
okay and i give the camera a little
shake whilst i'm doing it you can see
both a sharp picture and a blurry
picture we're getting a blurry picture
from the long exposure and the led light
building up and a sharp picture from the
moment the flash fires and that's the
principle we're going to use to capture
the movement of sophie dancing
with the lighting basically set let's
have a look at the effective movement
because that's the whole purpose of this
to capture and show some movement so
sophie is primed she's going to do a
little bit of a dance move between there
and about here but i'm only going to use
the led light to light sophie so the
flash is currently turned off
i've got it set to about a two second
exposure let's take a test shot and see
how this looks sophie are you ready
okay i'm gonna come around the back of
the camera and in your own time away you
go
so that's a two second exposure and you
can see that sophie isn't sharp anywhere
because she is constantly moving but she
is recorded the entire time because the
led is on the entire two seconds of that
exposure
so now i'm going to add the flash into
the mix as well so we'll still have the
continuous light but there'll be flash
firing during the two second exposure
the question is how bright to make the
flash well that's what my flash meter is
for i'm going to guess that sophie is
going to finish about here somewhere so
let's just take a flash meter reading
we're looking for f 5.6
which we've got so this point is about f
5.6 i could put a mark on the floor if i
wanted to be absolutely accurate but in
reality
you can't be that accurate it's not that
easy so this is about the right position
for sophie to end up
sophie are you ready okay let me put my
transmitter back on the hot shoe of my
camera
okay sophie in your own time away you go
and straight away you can hear something
isn't right the flash fired at the
beginning of my exposure and sophie has
blur going across her face she's not in
the right position for the flash
but nothing actually went wrong this is
exactly how cameras and flashes are
supposed to operate it's called first
curtain sync the flash fires at the
beginning of your exposure time
and that's where slow sync flash or
second curtain sync flash comes in it
allows me to move the position of the
flash firing from the beginning of the
shot which is the normal position to the
end of the exposure time and that means
that sophie will move she'll get here at
the end and then the flash fires and she
should be frozen at the end of the
motion
that's the plan sophie are you ready
let's see if it works here we go
same settings nothing's changed sophie
in your own time
and that worked absolutely brilliant so
the beginning of the exposure we get all
of the blur and then at the end when
sophie has reached the flash nice and
close then we get the pop of the flash
and that freezes everything that works
brilliantly
and that's it that's the entire setup we
are ready to go sophie i say we sophie
are you ready okay sophie's got the hard
work to do i just have to come back
behind my camera and sophie in your own
time away you go
[Music]
okay
go for it
perfect
[Music]
sophie is obviously a brilliant dancer
but for a different look we can add some
props into the scene so i've got some
fabric here for sophie to use we've got
some basic white fabric i've got a flag
and i've got some of this organza which
is really nice let's see how this
changes the pictures so sophie i'm going
to give you some of that we're going to
turn the room lights off of course
and we're good to go
okay are you ready okay in your own time
away you go
[Music]
i'm ready
[Music]
okay
[Music]
i'm ready
wow
[Music]
trying to squeeze a full length dance
shot into 15 feet less the space of some
lights and that's quite a bit it was a
bit of a challenge but it was a
challenge well worth undertaking sophie
did a fantastic job with some assistance
from hannah and the end results i'm just
really really pleased with them now if
