Hi, this is JP Morgan and I'm Julia Rose today's model
Julia is here to help me illustrate. What?
high-speed sync is
Why you use it what you're trying to accomplish with it and then just have a set it up give you a great example
It's a little noisy here. But here we go
First off what is high speed sync high speed sync is the ability to sync your strobes with
Faster shutter speeds in one two hundredth of a second. That's basically all it is
But why do you want to do that? You want to do that?
Because I've got a very bright scene behind me here and I can't control that with my shutter
Unless I can go past one two hundredth of a second. So I want my aperture at 2.8
Which means I want to be wide open
That means this background back there is gonna be at least an eighth thousandth of a second
That's super super bright
Now if I go to shoot my strobes, I can't sync them at 8,000 a second so I can do one of two things
I can set Julia Rose out in the Sun and
I can sync that just fine because she has the same bad light on her face as we have in the background or I
can bring her into the shade I
can soften the light on her with a strobe and
Now I can start to try to balance the background to the to my strobe light on the foreground
But I can only do that by using high-speed sync
Which allows me to sink my strobes at faster than one to hunt of a second. The reason is because cameras have a focal-plane shutter
This is a focal-plane shutter
You've got to take a picture open close open close open close open close and with gloves at the focal plane shutter
There's a moment all the way up to one two hundred a second where the opens the entire sensor is exposed and then it closes
After one two hundredth of a second, it goes like this
open-close open-close
open-close
open-close open-close
Faster faster, it goes all the glows. Oh, yeah, just a tiny little slit
The first one goes across and the second one follows it so it's going like this and all it does is leave a little slit
That burns across the sensor. There's never a time when the entire sensor is open for a strong to go off
So the strong goes off why this is going through all your going to expose is a small little strip of Julia Rose's face
So we have to go to a high-speed sync. And what does that mean?
The strobe is going to pulse
the entire time that the shutter is going so pulls pulls bolts bolts bolts bolts bolts bolts both bolts
And it's going to paint the image in as it goes across the subject matter
So every section as it goes across will get poked in but it does it so fast
It doesn't cause any movement or problems and you get your image. That's why we use high-speed sync
I now have the ability to go to 2.8
Bring Julia rose into the shade where I get soft light on her face
get a nice beautiful light on her face from the strobe and then match that to the background by crushing my background with a
Very very fast shutter speed so I got 2.8 very fast shutter speed and a pulsing stroke little full volts
That paints in my image. So let's set one of these up
I had Julia Rose over in the Sun and I keep her in the Sun where the background and foreground are the same exposure
There's my image. It looks okay, but I want to soften the light on her face
So I'm gonna bring her into the shade now that I'm in the shade. I'm gonna take my first exposure my first exposure
I'm going to meet her for the background Julia. Rose is very dark
So now I'm gonna take an exposure for her face. Now the background is blown out. So
I've got to use my strobes to balance these two to set up high-speed seek with the bajas
I'm gonna put the transmitter on my camera turn it on
I'm gonna hold down the high speed sync button to where it's blinking. There we go
Then on the back of the baha
I'm gonna hold down the top button h/ss button to go to the H now
I can go eight seven six down to one which is the least power up to seven
Which is the most power now I can high-speed sync
So we're gonna start with seven with the most power and we're gonna do a shot and see what we get
So there's eight seven and it's just way too bright. So I'm gonna dial it down to h4. There's an exposure at h4
still a little too bright, I'm gonna dial it down to h2 that
Looks much better to me. It becomes a creative decision now at this point. Do you want your bright background brighter or darker?
And how is that going to balance? It's up to you to make that decision on what you creatively like. It looks nice
So here's some images. I shot at different shutter speeds. Just playing with that background. Just seeing what it looks like
Julia Rose is beautiful. These images look fabulous. Take a look set your shutter. And then Dahlia strolls to match it
That's the secret to high speed sync when you change your shutter redial your strobes to match it because it's going to change them
That's all based on the principle that 2.8 or 3.2. Whatever your aperture you've chosen is not changing. Keep that constant
You're gonna change your shutter until the background looks right and die your strobes to match it
So there you have it how to do high-speed sync
I love high-speed sync because it giving you so much control when you're out on location
But this is really specific to the Baha B 6 check out your platform. Make sure you know how to use your
platform because it's gonna be different look at your manual just it practice with it because when you get out on location
you want to be able to do it quickly and just
Really seamlessly, so you get the great shots
