G'day flash gurus, this question highlights my naivety, but anyway,what are the power options for off camera flash/lighting in remote locations where you cannot lift a rock and find an outlet?


I have the 580, umbrella and tiny softbox set-upso I know how to charge batteries.


But with the next step up in softboxes and lighting how do you get the light to turn on?


In some pictures posted here the lighting set-up looks as though it is about ready to gang tackle the subject/model(little old fit footballer).How is all this gear powered?


Thanks, Steve.
