I am new to lighting but I am inspired by the Strobist.
I am trying to put together the best, most flexible lighting rig for all occasions. I'm thinking "reasonably portable", not "fixed studio".
I have: 1DsIII, 5D, a selection of L glass, Manfrotto tripod & heads.
Budget is: "Money no object". If I can't afford it, I'll wait and save.
So, my thinking is:
1 x Elinchrom Skyport transmitter
2 x Universal receivers
2 x Canon 580EXII
2 x translucent umbrellas
2 x white umbrellas
2 x Manfrotto Nano stands
2 x Lite Tite umbrella swivels
Coloured Gels (the subject of a different thread)
Will all this work together?
Have I made any obvious errors or omissions?
Or am I being stupid in some other way? 
Andrew
