So guys

I'm doing my first organised fashion/portrait shoot today, unfortunately the British weather has let me down a bit but I will not let the experience go to waste.

My Question is: I have three strobes 430exII 550ex and a 580exII I am planning to use the 550ex as the master on camera for fill and the 580 as key which leaves the 430 on separation and hair light duties. does this sound about right?

Also when setting the ratio's and groups I know the fill will automatically by group A and the key would be manually set to group B but would the key be set to group C or B??

If group C then how do you set the ratio's between the three flashes? or are the group B and C ratio's the same?

I know it's just me getting a bit jittery but does anyone else seem to forget everything they have learnt the morning before a shoot??? :thinking:

Is there anything else i'm obviously missing... any help would be great
 
I know I should have asked these questions last night when everyone was online, but is there anyone that can help? or am I just going to have to experiment when I get there? Not that I mind that of course.
 
I guess that is a no then... oh well I will just have to experiment when i get there.. lets just hope it does not rain...:razz:
 
I'm sorry I don't know :(

:lol: at least you bothered to comment.. I can't believe out of all you canon strobists and veterans of flash nobody knows or could be bothered to explain how to set the bloody things up!!

I really struggled today with all the channels, ratio's and groups then with the weather and the inexperienced model I probably got one maybe two shots i'm happy with... oh well there's always next time.
 
Sorry, I wasn't online and doubt if I could have helped anyway. :(
 
Unfortunately I didn't see your post earlier and would have tried to help....although "a strobist", I am not.

You can select a ratio for group C by selecting A:B C and then toggling the SEL button until "ratio C blinks"....you then set the output level you want on that flash/group.

Hope that helps....even if a little late.

dont use C as key, C is background, thats why no ratio.. if you try using a or b as background instead then it will screw up the exposure. A is used for fill, B for key..

Maybe I'm mis-understanding you Tristan but it is possible to set a ratio for C. If you set FEC then it's fine, if you don't set FEC then it'll mimic the output of channel B.

Bob
 
there is mention of using FEC on group C to control background exposure seperately from the A:B Ratio of key and fill. That's because Group C doesn't use ratios per se, but rather power levels in fractions, which are independent of the A:B levels. That's a good thing, because you can then adjust background intensity for high-key or low-key backgrounds while still getting correct E-TTL exposure of the subject.
 
Got ya...we're saying the same thing in different languages.

PS...glad I've only got two flashes

i wish canon made it alot easier to use and understand, nikon got it right with there CLS

thats cos canons are for clever people :D

*this is a joke not an inflammatory comment*

Thanks guys for commenting

your not wrong Bob I think I will just use the two in future one on camera as fill and one with a soft box.....as key. moving the bloody things around and changing the settings every time the model moved was half the problem...:bang:

Tristan, never having used the Nikon system I can't comment but you never here them asking how to set the bloody things up I think it just works...:'(

And as for you David your nicked :police: for instigating a flash mob riot and inciting brand related violence...:boxer:
 
The joy of canon strobes is you get so annoyed with their stupid setup (and the fact they're line of site) you end up sticking them all to manual and using ebay triggers.

This teaches you loads :)

onform - if you were worried you'd not be able to shoot on set you should have tried a test setup in your front room so everything was happy when you got to the shoot.
