I am quite new to using a flash and would like to experiment a bit with off camera flash.
I have a 430ex flash and a 20D.
Could somebody please give me some advice how I can use these to setup an off camera flash.
Could I still use my build in flash for the front flash in that scenario?
I realize that the 430 can only be a slave but do not really understand how the whole off camera flash thingy works
