Lighting / Re: 600EX-RT Manual Question
« on: February 07, 2014, 05:04:05 PM »
Steven,

You are making far more work out of this than it is.

First, you cannot use ETTL, it just is not what ETTL is designed for. Second, taking just the small highlighted section illuminated by the hand held 600 has masses of exposure latitude because of the way you can adjust the exposure and then blend it. That is why nobody I know brackets the in hand flash, just know that you get the rough exposure you want of anything at a certain distance; I know f8 and 10 feet @ half power gives me a second story burst, at 20 feet it is a ground floor burst.

Myself, and everybody who I know that does this, just uses manual flash mode and pops away, if you don't have the remote viewing capability just keep varying your flash to subject distance, zoom setting, and angles.

But, because this question has been bugging me and you clearly don't want to go the ND filter gel route I have come up with a work around using just the 600's.

First, put the on camera unit (ST-E3-RT or 600-EX-RT) in Group mode, second, set each group to M and a different setting such that you would want to bracket, third, set the in hand flash to Group A, take the shot with the REL option. Then change the in hand flash to the next Group B, take a shot, then change the in hand flash to the next Group C, take the shot etc etc. This will give you five different exposures from the in hand flash.

Private Design, I think that this is possibly the smartest workaround imaginable! Thank you for this. I could just use ND filters, I'm sure, but I'm just loving this solution.

I agree that there is a lot of latitude to play with, but I can imagine certain senarios where I would want to go from close to both ends of the power spectrum between two shots, and I might not want to return to camera to set this (highlighting a feature, to filling a secondary room).

Also, when I'm trying to pin point the lighting to highlight a certain feature, I don't really want to be moving in and out, to change flash power, so that is why I have seemed a little against this option.




Thank you to everyone who has worked on a solution for me, thank you for you time!

...Do you know, can I have the off camera flash in my hand as the master, and then have all the controls on the remote flash. I know that I can set it up to Master Linked Shot, but I can't see a way of achieving it this way.
Yes.  In fact a viable work around for you might be to get a 33' OCF ETTL cord.  This will allow you to have the master flash in your hand while connected to the camera's hot shoe up to 33' away.  I use to have one of these prior to switching to the 600EX radio system.  They're well made and work great.

Get the 33' model, it's a non-coiled cord and moves nicely.

Thank you for the suggestion, but I'm really looking at doing this wirelessly, preferably with triggering with radio, rather than optical

This guy has apparently perfected the technique you are aiming for:

http://strobist.blogspot.com/2011/09/mike-kelley-two-speedlight.html

He is selling an 8-our DVD on this technique:

http://fstoppers.com/how-to-photograph-real-estate-architecture-and-interiors-tutorial-with-mike-kelley

Yes, this is exactly what I am looking to achieve, but with the built in radio tech, in the 600's. He either uses dumb optical, or Pocketwizards.

It just seems stupid, to clip a Pocketwizard, or similar to the bottom of a 600, seeing that they have a radio trigger built in. Just a massive waste of money, bag space batteries, weight... well everything reason I bought the 600EX-RT, and not just pocket wizards for my (now sold off) 580EXII's! I'm sure I am an exception, and for every other use, they have proved faultless... but trust me to need the one option, that it can't seem to do :( Hopefully someone can come up with this, I'm still hoping that I have just overlooked something!

He used to use dumb radio. Then he tried the PW, now he uses the 600's.

This is exactly what I do and I have never had a need to adjust the in hand flash power. The layered in shots give a huge amount of latitude, first with exposure, then with curves, then with opacity.

People who actually do this love the 600's and it is working well for them. In fact I know one real estate shooter for Sotheby's who has shot Nikon for over 30 years, and has got a 5D MkIII just to use the 600's and the 17 TS-E.

I see the Mike Kelley started with Optical flashes, and then pocket wizards, but I can't find anywhere where he says that he is now using 600's. Do you know where you read this? I'd love this to be true, as it means there must be a way of getting around this.

As for you real estate shooter for Sotheby's... it's great to hear that some people are switching from Nikon to Canon, on this forum, it always seems to be that Canon can't keep up, or isn't competitive anymore! Do you know how he is shooting hit flashes? Are they just in E-TTL, or is he having to return to the camera, to redial in the manual flash exposure, anytime he wants a change?

Thank you for you time

Steve

for some reason Canon don't support flash use and bracketing exposures at the same time.

They probably saved this for Magic Lantern which enables it :->

Massive +1... just imagine, ML on Speedlights, on the possibilities are endless. ML, if you are listening Second Curtain Remote, and Remote head zooming please!!!

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.

Nope this can't be done on a slave unit while it is linked to the master.   With radio controlled flash, the master and it's slaves essentially become one system and are controlled by the master.  Keep in mind there is two way communication between master and slave when configured as radio.

When configured as optical, there is only one way communication--a signal being sent from the master.  The master has no idea of how many (if any) slaves are out there.  Essential the slaves are completely independent and will fire only if it can see a signal from the master.  That is why you can adjust the optical slaves right at the slave.

You will need to switch to optical to accomplish what you are trying to do.

Thank you for your input RC. I fear that you might be right with this, which is a shame. Do you know, can I have the off camera flash in my hand as the master, and then have all the controls on the remote flash. I know that I can set it up to Master Linked Shot, but I can't see a way of achieving it this way.

The feature you want to use is apparently a mode called "individual slave" but it is only available when using Canon's older "optical" remote triggering system. Maybe you can use that instead?

Thank you for this SPTurtle! This might just have to do as a work around. It's just a shame that I sold off my 580EXII's, to upgrade to a 600, as I thought that this would save me having to buy pocket wizards (or similar) to find out that I can't do it! I can't figure out why canon wouldn't let you do this!!

Let me just get my head around this one. So you have multiple flashes all in manual and you're triggering them via a third party remote trigger on your camera? What kind is it btw?

Then you want to be able to change the power setting for the off camera flash and fire the shutter remotely using the speedlite or remote control? But it wont let you change the power? That's strange.

Is it in slave mode? If using wireless triggers you need to keep the speedlite in normal mode i.e not slave mode. This can cause issues off camera. That could explain why you need to put in on the hotshoe to change the power.


So a little more information.I have multiple flashes (2x 600EX-RT (and one ST-E3 RT)). I am triggering the camera current using a Honl remote trigger, this is plugged into the side of the 5DMk3. And correct, I would like to be able to shoot a frame, not bothered about the on-camera flash, flashing (I currently have it set to not fire - I could put the ST-E3 RT in it's place, but the 600 has the AF assist beam, so I'm opting for the 600) and have the flash in my hand (off camera) fire.. then change the power setting on this off camera flash in my hand, and shoot the next frame. Effectly Flash Exposure Bracketing. But with the 600EX-RT, in radio mode, it seems that I can't set it to just trigger the remote flash, it has so send the power setting from the camera. There is no -/+ option when in manual. It does give me the +/- option in ETTL which is highly frustrating!!

The way around this, is to buy a set of wireless triggers (Pocketwizards, or similar) but this just seems stupid, seeing that the 600EX-RT SHOULD save you having to buy triggers!!! ARGH

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!)

I've been poking around on the magic lantern website over the past month, but can't seem to find the answers to some very basic questions:
1) When using this in the intended fashion, do I still get to see the regular canon menu options (i.e. the focus modes, etc)
2) Does installation of this reset my canon settings to stock (custom button reassignments and such)?
3) Does pretty much everybody have the slower boot described in earlier posts here?
4) Do we know for a fact that canon refuses to honor warranty after installation of this?
Thanks for help, mostly I'm curious about question 1 and 2!

Replying to number 4, I read an article on this recently (found here:http://petapixel.com/2013/05/27/will-custom-firmware-void-my-warranty-canon-nikon-and-panasonic-respond/)

Basically from my understanding, Canon will honour the warranty, unless the point of failure is the new OS itself.

"So damage caused by Magic Lantern wouldn’t be covered, but any covered damage, whether or not you’ve ever installed ML before, will still be taken care of pro bono during the warranty period. Nikon and Panasonic owners, however, aren’t as lucky."

As for the other points, I haven't installed ML on my 5D3, but when I installed it on my 7D I didn't notice it change any of my custom settings back to stock.

Hope this helps

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!

This is a brilliant question. Right now I just seem to have kit everywhere!. Most of it fits inside my Peli 1510 case, and the rest is split between a large Lowepro shoulder bag, and various shelves and counter tops... I'm loving the metal cabinet upside down, for the lip sake... very clever!

Lighting / Re: Short comings of TTL flash, why the need for E-TTL
« on: August 09, 2013, 02:13:43 PM »
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?

E-TTL2 works in the ambient light, calculating the correct exposure by comparing the scene with just ambient & ambient+pre-flash, plus it takes the subject distance as reported by the lens into account. The result is an ingenious system where you can nail most exposures in varying light and distance and set the subject/ambient ratio with a turn of a dial.

This seems to be the answer I'm looking for, thank you. So just to give one example where TTL flash might fail is with a back lighting situation, as the flash might stop far too early, as the sensor would 'see' that enough light has come in through the lens, without knowing that the flash hasn't yet put out enough light, to light the subject. Is this correct?

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 :)
