Another product of Vizen marketing which they sent for review is the 810-RT which is a wireless flash trigger which is capable of highspeed sync.
This was my very first time using highspeed sync as my main camera body before was a Nikon D3 that had no built in camera flash and I only had an sb-600 flash so I wasn't able to trigger it using HSS(highspeed sync) unless I buy an sb-800,sb-900, or nikon Su-800 Trigger.
At first I didn't actually know how to use as it's more complex than my usual trigger which I had to just turn on to use.The first thing you need to do is Switch the Flash to "Others" both the RT triggers if you're using a Nikon Camera and Flash.
After set one of the triggers to Slave(this will be the one you will put on your off camera flash).
For your On Camera Trigger, Set it to Master. You can control 3 Channels at once and either set it to Manual or TTL Mode. Normally for off-camera flash I use manual mode as I have more control over my flash the power output of my flash rather than making my camera automatically get the exposure.
For your speedlight, make sure it is also capable of HSS and also is for your camera brand and supports TTL. Set your speedlight to TLL for it to read properly from your 810-RT Trigger.
One of the best feature of having this trigger is you don't have to go to your speedlight to change its power(that I keep forgetting to do), you can control the power of the flash (TTL or Manual) on the trigger that is on the hotshoe of your camera, this makes shooting so much easier.
Now for the real world test!
For this test I wanted to keep it as minimal gear as possible, and there is nothing more minimal than one bare speedlight and a pair of the trigger. I also wanted to maximize the high speed sync capability so I was shooting almost everything against the sun and overpowering the power of the sun.
Normally when shooting outdoors and you want to over power the sun, you would have to shoot with a very fast shutter(1/4000 to 1/8000) or a small aperture (f18-f22). The problem with using a fast shutter speed is that normal triggers can't sync faster than 1/160-1/250th of a second so you won't be able to use a your speedlight. When using a small aperture (and making your sync speed 1/160-1/250th of a second) you would have to Pop your flash almost at full power everytime and when shooting at that shutter speed and having your subject move fast you would see that you get some kind of silhouette as the shutter is too slow for fast moving subjects mixed with flash. So, the best solution is to use high speed sync to shoot at a faster shutter speed and shoot wide open which gives a really nice dramatic effect on the photos.
I was shooting with my Nikon D750 which has the max shutter speed or 1/4000 but the 810-RT trigger can sync up to 1/8000 if your camera supports it.
For the shots below I was shooting at 1/4000, f/2.8, at ISO 200-1600(I was changing increasing my iso as the sun set to compensate for my ambient light). My wireless trigger was in manual mode and I was changing the power from 1/8-1/2 depending on the distance of my subject to my speedlight.
I also had an opportunity to really over power the sun. We were shooting at around 12pm and the sun was backlighting the subject really hard as you can see on the hard shadow on my subject. Again I just used one bare flash Handheld and the results I got couldn't get anymore perfect, notice also the shallow depth of field I was getting which made the result very surreal.
I was amazed with the results of using High Speed Sync and the 810-RT trigger. If you're looking for a trigger capable of HSS then this something you can check out. The results you can get when shooting at a fast shutter speed and wide open aperture is very unique and not the usual photos you get when shooting with a flash outdoors. I would definitely play with this some more as I liked the results I got.
Thanks to Vizen Marketing for sending the 810-RT trigger for review. Thanks to my beautiful girlfriend for patiently modeling in the very hot day. Also to the great dancers Sarah Palisada, Rael Palisada, Angelika Adrias, Angelou Adrias and Kevin Lanon
