Mixing Nikon CLS + traditional radio trigger

Requirement/issue

At a recent event I tried to use an on-camera speedlight (SB-800) as a master  and a off-camera speedlight (again SB-800) in a CLS  setup where I would hopefully use the off-camera flash as a silhouette light.

(CLS = Nikon Creative Lighting System – where you can remotely fire flash using TTL – either with the on-bard flash (on some cameras) or another speedlight set to master. As well as using TTL you can also add compensation values to each group of remotes from the master.)

Although I’d tested them before getting into position (so channels and groups were fine) – the remote flash just didn’t fire. It was relatively in line of sight so that shouldn’t have been the issue, however with the speedlight facing forward the detector would be at the side of the speedlight and it was behind a shoot-through umbrella. I now think that possibly the combination of these meant that the signal from the master speedlight wasn’t getting through to the remote. It was also in a party environment so there were other lights which may have caused issues.

Turning the shoot-through umbrella to a bounce one may have worked (it’s a convertible umbrella), but there wouldn’t have been time for that.
Taking the umbrella off may have also helped, I should have tried this but alas didn’t.

 

In the past I’ve used a remote flash like this but using a radio trigger rather than Nikon CLS system.
I didn’t go for this setup on this occasion as I needed a on-camera speedlight as it was too dark without it.
So alas I made do without the remote speedlight.

 

After the event I investigated the option of using an on-camera speedlight but also a radio-triggered remote and my results are below.

 

Only one Hotshoe

The initial issue is that cameras only have one hotshoe. The on-camera Speedlight obviously needs to go in this. However most radio-triggers are also designed to go in this. They both can’t.

 

Other connectors

Thankfully there are a set of other connectors available.

PC socket: The PC socket is the standard/traditional method of firing flash via a cable.

My D800 has one:

D800 PCSync

And so does my SB-800’s:

SB800 PC Sync

 

Usually you’d use the PC sync on the speedlight to fire the speedlight itself i.e. incoming signal. However it appears that this socket is by-directional.

 

Sync Connector: It transpires that in addition to having the Skyport trigger via the hot-shoe there is also an additional SYNC connector:

SkyportTransmitter

 

Cable

The Sync connector on the Speedlight is smaller than the usual jack – it’s a 2.5mm jack socket rather than 3.5.

So the cable needs to be a 2.5mm jack to PC sync connector.

Thankfully one of these is supplied with skyport transmitters. I hadn’t taken it out of the wrapper let alone out of the box so I wasn’t really aware of it until investigating this issue.

Connection + Test

I wasn’t sure if it would work correctly and wasn’t sure which PC sync to use – the camera or the speedlight. My thoughts were that if the on-camera speedlight was in TTL that there may be a flash sync speed issue, particularly with the TTL pre-flashes. So I tried both.

Standard settings – both worked.

Pushing shutter speed up to 1/250th – both worked!
(My skyport are the “SPEED” variety so are faster than the older non-speed variety)

 

To reiterate, the setup is:

Remote Speedlight: Set to manual power, skyport receiver plugged in to the PC sync port.

On-camera Speedlight: Set to TTL, mounted on camera hotshoe.

Skyport Trigger: Connected by above cable, to PC sync port of either camera or on-camera speedlight.

 

So in future I may try this in such scenarios. It’s handy to know that it’s possible to mix TTL/CLS and manual radio triggering.
Worth noting of course – since operated by a standard “GO” signal radio trigger- you can’t control the power from the camera. Pocket wizard have made TTL capable radio triggers (FlexTT5/MiniTT1 for firing and AC3 controller for varying power) but they’re considerably more expensive that simpler radio triggers that just send a “go” command.

 

Mounting Trigger

Found an additional issue worth noting:

Not wanting the skyport trigger dangling by a cable which can come out I considered mounting the trigger to the speedlight via something like velcro or elastic. In testing this I found that if you place the trigger flat against the speedlight – trigger: the flat side with buttons, speedlight: on top of the flash head – that the signal would not get to the receiver. I imagine this is due to interference from the pulse of the speedlight firing. Instead I think I’ll attach the trigger to the side of the speedlight with elastic.

Burning Man 2013

With the sudden excitement of 2014 Burning Man tickets becoming available – I’ve remembered that I’ve STILL not done a public Burning Man Gallery. I went last year (2013) and had a press pass so I could publicly share my photography 🙂

I made business cards so that I could give them to all I photograph so I could give HighRes photos away as a form of gifting. As such these and many more have been up in a private gallery, but I thought it about time I made some public!

I took my D800, a couple of lenses and a speedlight. I was intending to do a mini studio at dusk – however our camp (Cabana Club) had it’s camp meals around that time and so I missed the opportunity other than a few in the camp! I’m not going again this year – but hopefully soon – and then I think I may make a special effort e.g. ask someone to keep food aside for me.

Dust wise – I bought a cheap waterproof housing – kind of a bag – but realised that to put the camera in I would need to take the lens off! SO not the best in a dust storm. So I just took the camera out as it was and put it in a bag if there was a particularly bad dust storm. D800 is weather sealed anyway. Also bought a can of compressed air before getting to the Playa. Anyway – this isn’t supposed to be a blog post about photography on the Playa – but instead one to share photos – so here are my favourites.

D800 at long last ?

Woohoo!

Well maybe……

Rumours are currently rife that the camera I’ve been waiting YEARS for may finally be with us – the update to the D700 i.e. D800.

Why do I want a new camera and why have I been waiting for so long ?

For those that aren’t camera boffins – generally the race for more and more Megapixels in SLRs slowed down considerably over the last couple of years – and instead camera/sensor manufacturers have been consentrating more on low-ligh or High-ISO performance i.e. making the images less grainy/noisy when you crank the ISO up. Recent cameras such as Nikon D3s have had phenomenal High-Iso performance – with next to no noise at ISO 1600+

(If you don’t know – the dots/bits in film was called grain as it was due to the film emulsion, but in digital cameras it’s generally called “noise” as it’s due to electronic interference or noise…. hmm not sure if I explained that V well 😉 )

Now I use a Nikon D200 – this camera was announced November 2005! That’s almost 6 years ago – aeons in DSLR terms.

Why didn’t I upgrade ?

Well the options were –

D300 – more of an update than an upgrade. Didn#’t want to spend my money for just a smaller update.

D300s – and update of an update – as above really

D700 – Although much better camera it still only had 12Mpx and I did fancy more, especially for studio work. And then later on as Video comes into the frey – D700 just doesn’t have video. Not that Video was top of my list – I’m not dying to take moving images – but I just didn’t want to loose out.

D3/D3s/D3x – Too big (+pricey). I want a small body D-SLR.

So in effect I’ve been waiting for a D700, with more Mpx, and Video.

 

So it seems it’s finally here:

http://nikonrumors.com/2011/10/09/nikon-d800-specs-recap.aspx

Woo hoo!
But at 36Mpx (!!) it sounds like it’s more likely to be a baby updated D3x i.e. studio camera rather than a baby updated D3s – which is probably what would have suited me better.

My preference would be for a High-teens / low 20’s, small body camera with great High_ISO performance.

BUT I’ve been waiting so long for this – I’m damn right going to get it. So come November when allegedly it’s going to become available – I may be very very poor 😉

Here’s crossing everything hoping that the Nikon announcements on/around the 24th make me happy.
