:) yes it's me again.. So I have a flash I bought last week, and am wondering if I can do what a friend of mine does. he puts the off camera flash on a stand and uses it kinda like a stand alone flash for things.. can I do that with mine.. yes I looked at the 2 inch book to see.. but Im a dumba** when it comes to the actual names of things i like to refer to things as .. you know that lil button with the thingy over on kinda side of that thingy.. :)

anyway the flash I bought was a sigma EF-530 DG SUPER

i believe the sigma doesn't have a built-in slave function like the 580exII does so you'll need some kind of a trigger/receiver set that does the job for the flash.
you have many choices that rage from 25 bucks (cactus pt04/V2) to 200+usd.
i'm using the cactus set, you can get it via ebay for like 20+ bucks including shipping from hong kong. they're a little plastic and some flashes are rather uncompatible (your flash should work just fine) but otherwise a great deal and a nice set to start with.

here's some reading you can do.

I went the fleebay path and I would seriously consider using a snyc wire instead (see flashzebra)or get at least Cyber syncs or Skyports instead if you want wireless (non eTTL that is). I use a cable & optical in combo a lot and works great (for when you get more strobes).

Photomom1981, I don't know if you still have any questions about this flash, but there is a feature it has that many other shoe-mounted strobes don't...a built-in optical trigger. You can set this flash up off camera and it will trigger via the pop-up flash on your XTi. Here is a link that will explain where the option can be turned on...basically, you choose the slave flash mode. You can even manually select the output the Sigma will fire, from full down to 1/128. Here's a link with some more information:

Hope it helps.

That pretty much covers it. In short, if you want to trigger the sigma flash off camera via your camera's built in popup flash just keep hitting the mode button on the sigma flash until you see "C0" appear in the display. That'll tell you it's in optical slave mode. You should also start to see the red light flashing on the front of the sigma flash. That's the sensor that the sigma uses to detect another flash going off so make sure that part can "see" the flash go off on your camera. If not the sigma won't fire under this setup.
