Help - can all of you smart photographers out there in AP land put a bumbling newby straight. Im trying to work out whether or not to buy a light meter now or wait for more equipment. I have 3 yongnou460s flashes with ebay triggers, can I get a light meter that will trigger these to help determine settings? Sorry if this is dumb, but I am really enjoy studio style (sort of) shooting...thanks for your help. Feel free to treat me harshly lol
