414BFcFy2sL Hey, Everyone!  This is another product review.  This week it's on Speedlight Triggers.  I have triggers that I use for my speed lights and my studio lights.  But the ones I have are manual only, and I don't have the flexibility with the ones I have to turn certain flashes off without going to the flash to do so.  I'm shooting a wedding next month.  For the reception I'm going to have some speed lights on stands to create some backlight, and I'll have a flash on my camera for main light.  The backlight flashes will be on opposite corners, and I want to be able to switch the closest one to me off without having to go to the flash.  I just want to push a button on the trigger on my camera to do that for flexibility.  I'm looking into a lot of options to do this.  With Pocket Wizards I could do this, but Pocket Wizards are very expensive.  I turned to my favorite inexpensive speed light company, Yongnuo, for the answer.  I purchased the Yongnuo 622N TTL transceivers and the 622 TX TTL transmitter.  I got three transceivers and the transmitter for the same price of one Pocket Wizard. _DSC6273  Now I normally use manual only flashes for all of my portraits etc., but for gun-on-the-run type of shooting for receptions I want to use TTL on my camera.  The Yongnuo 622N lets me put the trigger on my camera, and then I can put my TTL flash on it.  It has a pass through hot shoe so all of the information from my camera goes to my TTL trigger and flash at the same time.  I can then set up other flashes elsewhere and transmit TTL to them.  I can also adjust the power of each flash independently from my camera without going to the flash itself, as long as the flashes are TTL.  I can use the same setup with a TTL on my camera and manual flashes remotely, and the manual flashes will fire.  I still have to set the power on them manually though.  This is the setup that I'm going to use for the reception.  I'll have a 622n on camera with TTL flash on top of it.  Then I'll have manual flashes mounted on stands and group them, one on "A" Channel and one on "B" Channel.  Then from the trigger on my camera, I'll be able to change the channels to cut on or off certain remote flashes.  Problem solved!!!  This is all done with the transceivers one alone, but with the 622N TX transmitter on my camera, I can also control the individual settings of TTL remote flashes.  I won't be using the 622N TX at the wedding, but I went ahead and got it because it will come in useful for small shoots like Christmas photos or something I'm trying to do real quick when I don't have time to really set up a big set.  I do believe for studio lighting and formal portraits I'll still rely on my manual flashes and strobe so I can dial in my exposure manually.  Triggers can be bought for both Cannon and Nikon camera systems.
