You've got the 3 items correct. i.e. lightstand, umbrella, flash holder. You'll need PT04tm set if you'd like to trigger it wirelessly. In future you'll need the extra receiver for PT04tm should you get an additional flash.
im planning to buy a starter kit for flash photography
i already browsed your website and planning to buy the lightstand
and the umbrella and flash holder with the hotshoe.
i also want to buy a trigger but currently quite confused because there are so many things. Could you suggest for me which one is suitable for me. currenty i owned 1 sb 800 and planning to but a 2nd flash in the near future. and i prefer to trigger the flashes without cables.
thanx a lot for your help
