Lighting / 600EX-RT Manual Question
« on: February 05, 2014, 12:25:42 AM »
Hi all,

So I think I have quite a specific need, but can't find a way to make this work. It seems like this should be a no brainer, but can't find a way to make it work.

So, I'm photographing the inside of houses... High Aperture (f8-f11 around there somewhere), trying to collect a little ambient light, to show what is outside the windows (longer shutter speeds, i.e. tripod)

Low(ish) ISO (as I'm tripoded, may as well reduce the excess noise)

So I'm bringing the up the light inside the room with speed lights (600EX-RT's) and I have a wireless remote to fire the camera (I know I can uses the 600's to do this, but it just seems easier this way).

What I would like to be able to do, is walk about with my 600EX-RT in hand, and point it at where I would like to pin point a little extra light. Then set the 600EX-RT that is off camera (in my hand) to manual, and choose my power setting. But it seems that when the flashes are linked, I can only set the power level by adjusting it on flash in the hotshot. However, I would like to be across the room, with flash in hand.

This results in me taking a picture, walking back to the camera, changing the exposure, and then walking back to where  I want to hold the flash, to light a specific part of the frame.

Does anyone know if this possible.

I know it's possible if I had a flash with an optical trigger, as then I can just set the flash to whatever power rating I want, and trigger it with the on camera, flash. It's basically this function that I am trying to recreate.

Thanks for reading, and any light you many be able to shed on the matter (sorry, crappy pun totally intended!)


Animal Kingdom / My first go at Biffing - Am I doing this right??

As the subject says, I'm kinda new to Birds in Flight. But the other day, I happened to observe a pigeon making multi passes across my garden. It piqued my interest, enough to watch it for a while, only to notice it would fly to a near by tree (Close enough to warrant at 70-200 on FF (I swear I'm not the only person who judges really world distancing in mm FL's!!)) test the durability of a twig, and one decided, go about breaking on free, before flying off, I assume, to build it's nest.
I thought this was a golden opportunity, so here is the resulting picture... any feed back would be appreciated!

Lighting / Short comings of TTL flash, why the need for E-TTL
« on: August 09, 2013, 10:29:46 AM »
Hi everyone,

I was just looking at the theory side of flashes (very clever little bits of kit!) And as far as my understanding goes, with TTL, the flash will just push out light, until the sensor in the camera tells it to stop, i.e the correct exposure has been produced.

So the question, why did the need for E-TTL, with the pre-flash system come about? In what situation does E-TTL work, where TTL does not?

Thanks for your help, it's just bugging me, and I thought that someone here might know :)


Lighting / Looking for C Stands in the UK
« on: July 21, 2013, 06:17:31 PM »
Title says it all. I'm looking for C Stands (along with boom arms)

I have looked into this a little though, and have read good things about the Lumopro C Stand, and Avengers C Stand... however neither seem to be (easily) available in the UK.

Now one make I keep seeing is the Interfit INT308 C-Stand and Boom Arm Set.

So the question I guess I am asking, is what brands do other people use, and does anyone have any experience with this company?

Kind Regards,


EOS Bodies / Download Firmware 1.2.1 link for 5DIII
« on: April 26, 2013, 08:03:54 AM »
So I've found a link to the new firmware... I'm not claiming any responsibility for this, but other people on the site seem to have gone through with it, with good results. Apparently someone got a copy of the new firmware directly from Canon, on a memory stick, when they sent in there camera.

Let me know how you fair with it, if you do decide to try it :)

Happy shooting

Lighting / Taking Radio Triggers In Hand luggage on Planes

Can anyone tell me if I'm going to be allowed 600EX-RT's and a ST-E3 RT on the plane in hand luggage?

EOS Bodies / 5D3/1D X Focus Assist Beam Fix On The Way!!!
« on: February 06, 2013, 12:39:04 AM »
We've just heard from Canon, over on their own forum, that they have acknowledged the problem, and a fireware fix should be in the pipeline :)

Just relaying the news.

I'm now a very happy 5D3 owner...

[mod edit: changed title to reflect Canon's statement that the fix applies to the 1D X as well]

Lighting / Specular Highlights... Feed Back Please

I've been trying to work on specular highlights, and I think I'm there, but might just have this completely wrong. Just looking for a little feed back please :)

EOS Bodies - For Stills / Can someone help me with low light settings
« on: October 06, 2012, 03:53:00 AM »
So, this problem has come up from working in nightclubs, where I am trying to get a night exposure for a human subject in the foreground, but have a shutter speed of around 1/30 or so for the ambient background.

I have toyed around with a couple of variations, each coming close to what I would like, but nothing bang on the nail.

Ideally I would like to have control of my aperture and shutter speed, and have the camera work out the ISO for me. The first problem I encounter is once I have mounted my flash (as this point I feel I should talk equipment. 5D3, 16-35 MK2 L, 24-70 MK2 L & EX 580 2) the auto ISO options become constrained. I have read into this a little, and have found a couple of ways around it.

Option 1... I set my ISO 4000, I set the shutter speed 1/60-1/200 and get the choice of aperture I want. Fine, except if I don't want my ISO higher than 4000, but I do want my shutter speed a little longer, say around the 1/25-1/30 mark.

Option 2... I set the Shutter speed to whatever I want 1/30 or whatever, have the auto ISO on (normally locked out at 400 max) but with the safety shift on ISO, with the ISO parameter set to a max of 6400. The problem with this is I don't like having the lens wide open. Drunk people in clubs tend to sway, and the fine depth of field result, inevitably, in people swaying out of the sweet spot. Plus on the 16-35 f4 is noticeably sharper than f2.8.

Option 3... I set the aperture at f4 on Av mode, and have the minimum time value parameter set to 1/30. This seems to work perfectly, until you switch on the flash, at which point, it forgets all about the 1/30 minimum shutter, AND locks out the flash to ISO 400.

Can anyone think of a way to have my minimum aperture set to f4, whilst I retain control of the shutter speed, and have the auto ISO range up to 6400 (or at least higher than 400!)

Sorry if this seems a trivial question, but I can't for the life of me figure it out.

Many thanks

EOS Bodies - For Stills / 5DMK3 Slow AF?
« on: March 25, 2012, 12:16:40 AM »
So I was wondering if this was just me, but the AF seems to hunt for a while before finding the lock. I've come from a 7D where the AF seemed lighting quick, and this has left me a little disappointed. Can anyone else confirm if the AF in the 5DMK3 is indeed slower than the 7D.
My set up I'm running (incase anyone has any input in why the AF is quicker with the 7D over 5DMK3) EF 16-35mm L MK2 USM with a 580EX2 Flash.
Any help would be appreciated :)
