Remote flash question
I have a vague understanding of how a master and a slave flash operates. Could someone give me the gist. Also if this is in built in most dslr's and modern flashes why do accessory such as transceivers exist. Finally if you where to have a mobile lighting setup on the super cheap what would it be?
p.s. I've had some experience with external flashes (Olympus fl-36 that had a recycle time long enough to change lens) and I've been renting the pro Nissin model. I don't know much about how to use it but from the little I know its been great.
Finally can someone point me to an article on the technical basics of using a flash system that won't be ''tldr''
Finaly # 2 no need to point out that I'm being lazy. I'm aware. thanks
