Hey, this is Scott of PhotographyBanzai.com, Today I'm going to show you these Yongnuo YN-
622N i-TTL wireless flash triggers. They're transceivers and they use radio
frequency, so that means line of sight is not an issue. And you have nice long
range. And they're interchangeable. So you can buy a set and use one on the camera
or flash. It doesn't matter which one. Just show a quick overview of the device
itself. Hotshoe on the top.. Got some buttons on the side: One for "channel" and
"test". GP is the grouping and different "mode". The "mode" defines either TTL or
manual control. And then of course the on/off button. I have one unit on the camera up
here, already on. So just connect this one to the flash. This is a SB-800. Turn it on... the flashes
already on, so I put the flash into TTL mode and that's all set up. So a quick
overview of what I've learned...
about these triggers so far. You can always look at specs on the internet to
see what that says they'll do, but what I've learned is that to control power
from the camera itself... You have to go and use the buttons here. There's no
actual -visual- to say what power level you're at, which is kind of a hassle. So
if you're in TTL mode and you change the power from this unit.. It'll be steps of
the actual exposure, so what you would do is you'll hold one of these buttons down...
And then you'll see it'll cycle through all these things here. These are the
groupings and these are the channels. So I'm in the first channel and grouping 'A'.
And the flash is also in that. So if I wanted to change the power level... Which
...this is... it seems confusing in the directions, but it's not really
confusing. But I want to do it up, I'll use this button, or down I'll use this
button. So let me have press to make the everything active. Then you hold this
button down. See how it cycles? So I go like that... that means I just increased the
power one notch. By using this button, holding it down, and letting it cycle to
this. And letting go of the button. So if I want to redo what I just did, I'll use
the second button hold it down and then let go. See it flashed, so now it should
be standard again. You can also reset it by turning it off turning it on. But I've
also learned is that the exposure compensation and also the flash exposure
compensation do affect the actual exposure. So if I want to use... I'll use
flash for this case. There's a button right here on this camera.
This is a D600. You hold it down and then you add a negative compensation to this.
A "-3"... and take a quick picture. And then I will go into the setting
again, and increase it to as much as possible. "+1" in this case.
Take another picture, and once it finishes writing to the card... Here's the
second picture, and the first. You can see a definite change in exposure, or...
not actually exposure, but flash power. Anyways, so you can see
that the compensations do work. The actual compensation here which has a wider
range also functions. However, what I've learned is that when I have a flash on
here this TTL, and also with this set up... The exposure compensations will change
both this and this at the same time. Which is somewhat of a hassle. I would
prefer some way to just change the power on here. Because I have a SB-400 and it
doesn't have any actual control to it. But I have noticed
that the flash compensation does seem to affect the power coming from here a bit
more than from here. Another thing that you can do
with this setup is if you hold this GP mode button down. See how that changed.
That means it's in manual power mode. So you can do the same thing that I showed
before with this to change the power. And it will change the power from this unit
or whatever grouping you have set. So that's a nice feature. One other option...
Let me put it back into TTL. See it flashes to green again. So I've noticed
that you cannot change the power when you're in TTL mode from the flash at
least it doesn't appear to. So if you add compensations to the flash
when it's in TTL it doesn't function as you would think it would. What we can do
is just put the flash into actual manual mode and this does work. So if you want
to avoid the goofiness of changing powers slowly from this unit, you can
just go into manual and just do it of course simply like that. Which is
probably the preferred method most of the time. So that's a quick overview of
these units... Actually one other thing I should mention. It has an AF button. Let's
see if I can... there we go. So that's a nice feature to get AF with the light if
you need it in dark situations. Other than that, that's about it. It has
multiple channels of course you can look at the specs, but I just have two at the
moment. Those are the Yongnuo YN-622N i-TTL
triggers. For the price they are definitely great option.
