How to shoot motion blur portrait with continuous LED light and Flash

hello I’m Urs Recher, I’m Karl Taylor
and welcome to another How-to video And Urs this one’s quite a special one isn’t? It is very special yes and it will be tricky but I show you what I’d like to do. Talk me through it. All right, first of all we just start here. It’s basically just a
simple beauty setup, which means softbox and softbox or a beauty dish. The important thing is they are both equipped with honeycomb grids. We’ve got grids and a grid on that beauty dish. Exactly So the goal is that this soft beauty
light hits the face only but leaves the rest of the body untouched. In shadow here. Exactly. So this only goes here and the rest of the body dark.
And that’s what the grid is doing? The grid is stopping that light getting down here, keeping the light directional. Exactly. Because a softbox or this beauty dish
has a light angled 180 Degrees, so it would illuminate everything, so this
light just comes out like that and this comes even out I like this and just hits from the chin upwards. So two lights ar only hitting the face, nothing is hitting the body. Exactly. What’s this thing going on here? That’s a continuous light and
that’s an LED continuous light. LED has the big advantage that we can
actually change the color temperature on it So we can, if I reach it, we can
have either daylight or Tungsten. So 5500 Kelvin or 3200 Kelvin. Let’s explain the reason for this
continuous LED light here. I would like to combine the two light
natures of continuous light and flash. I use the flashlight to have an
absolutely sharp portrait, some sharp face and all the rest
which is, let’s say that the hair light and light that we are going to reflect with mirrors on to the body. And with the jewelry? Exactly. So catching the jewelry and also catching the background. So we’ll have movement on this light and movement in the camera. So this combination of flash-freezing movement from your camera and a little
bit of movement from the model and the sequence in jewelry should give us a
little bit of Hollywood cinematic sparkle. Exactly that’s that’s the idea behind it.
You know that we have the movement, the more dynamic picture movements either from the camera or as well if she moves or if
she has wind in her hair you can actually see this but I don’t want to
have a complete blured shot. So that’s why the main focus on the eyes of course
they have 100 percent of the sharpness, due to the short flash durations. I
see two other little accessories in here, homemade accessories. One is a piece of
card over the top of the beauty dish and one is an ND gel just talk us through
that. Exactly. So, I’m using a white background. The white background
first of all that what we are going to reflect here is strong enough. If I
set up a gray or something then this is just not strong enough. So white
background that we get enough light back but then this light is already too close
to the background that even if I have the grids, even if I would have it like this you
know it would not hit the background but it has to be like that. So this light of
course travels like that, goes to the background and illuminates the background. But thanks to the grid, this light is not travelling like
this so I don’t need it. That’s like a constant rule in
the studio. I only set up the lights that I really really need. And I need this
part of the grid but I don’t need that part so I cover it. Essentially
you’re blocking the beauty dish from hitting the background to keep your background dark. Because I don’t need it, only on her. so let’s block it. So what about the ND gel up
here. I can see this is in the path of the continuous light coming to the hair.
So she has very bright blonde hair and this light is quite strong in combination with the quarter of a second exposure time it would be too strong so the blonde hair would be completely burnt. So
with the ND filter I just take it down in intensity. I don’t block it
completely with a flag so I just reduce it. But it’s super small which means the
the mirrors left and right get to all the light to reflect. But this part of the head gets blocked by one stop or so. I don’t know if you can see this. If I do
this, that’s what it’s doing. That’s pretty much it. That’s in theory and now we just have to get it done. Put it into practice. Are you Ready? Ready! Let’s go. We’re ready to go and as I can see the only modeling light you’ve got on is
obviously the LED light at the back. Exactly. The other two
lights are too close to the model, so of course they would be very important. They would create some blur. I really have to make sure that the only
light reaching the face is flashlight. And that the moving light, the
continuous light is moving the dark background and the dark parts of the
body. But it’s right, only the continuous lights is on. Shoulder down.
Good. All right. Eyes are good. Turn the body a little bit towards me. Some great results there Urs. I bet you’re pleased with those? Yes, with some of them. Of course every shot is experimenting. So every shot looks completely different. We
produced some nonsense as well. There is lot of combination is with the continuous light and the flash. But when you get a winner. If you have always one eye here the other on the mirror, sooner or later you just get the reward
from it. We have some amazing shots you know, beautiful look. Well done. So I hope you enjoyed this how-to video and we’ll see you on
the next one. Yeah looking forward to this. Bye
