All right chaps. I'm now wondering given Mike's comments re the flash overheat issue with HSS and given that I don't really understand Long tail sync but know a bit more about it since this thread started. Can I begin again and ask this question.
I have the 360 flash, the wave sync triggers, and my 5D3. I want to be able to use faster shutter speeds with this set up. What do you recommend I do next to achieve this. I will consider HSS or Long tail sync, even tail-end or whatever is the easest
If you can bear with me one more time I'd be grateful. Thank you
Tail end sync works perfectly well in many (most)? situations. All that it requires is a flash duration that's long enough and, within reason, the longer the better.
Yes, there is inevitably
some uneveness of ilumination across the frame, that's inevitable - but if you're using it outdoors then the contribution made by the ambient light will minimise its visibility, and if you're photographing a 'busy' subject then it will matter far less than if you're photographing (at the other extreme) a white wall. We tend to photograph white walls to create benchmark images to show just how good or bad the fall off of illumination is, but you really only need to use fast shutter speeds outdoors, where it is usually more important to be able to get a shot that would wouldn't be able to get without it than to get a shot that is technically excellent...
Godox Cells II is the obvious choice, though any trigger that can extract the HSS timing moment from the camera will work. Both HSS and tail-hypersync use the same timing moment (ie, fractionally before the first shutter curtain opens).
Bear in mind that with all these techniques there is a big hit to max usable light output, like a minimum of two stops and likely much more.
I'm not sure that the Godox Cells 2
is the obvious choice here... It's been around for about 3 years now and things move very quickly in electronics, and many people recommend the newer Yongnuo YN-622. I was given a Cells 11 just before they came out but couldn't do any really comprehensive tests with it as I didn't know anyone who used pro Canon cameras, it wasn't great with the consumer model Canon that I was able to borrow, but this may have been down to the slow shutter of the camera.
The Cells 2 has a passthrough hotshoe that you can plug the Wavesync into, but it's on the side of the unit, which is far from ideal. The Yongnuo YN-622 has the same facility but the hotshoe is on the top, which is much better. Using the Wavesync with either the Cells 11 or the Yongnuo will give you both tail end sync and full remote control.
Yes, you definitely will lose light if you use Tail end sync, but the loss won't be extreme if you set the shutter to 1/1000th or 1/2000th - the problem arises when the shutter is used at its maximum, usually 1/8000th, and there is absolutely no point in using such a fast shutter speed because although 1/8000th will severely reduce the contribution of the ambient light, it will have the same effect on the flash light too. It's a bit like driving your car down the high street at 150 mph just because it
can go that fast - maybe it can, but it really isn't a good idea
