Huy Nguyen this is for you, how to use the auto flash ability of the Digital Concepts 318AF Digital Slave Flash.
Glad you asked, I had to actually sit down and look at it for a bit, since I'd never used this function. Always nice to learn something new, even if it should have been something I had maybe played with at some point before now. Thank you good sir, for teaching me something.
Sorry for butchering your name, I am ashamed of that, especially since I should know that surname. I met a Nguyen a few years back, and specifically asked him how to pronounce it, sadly I've forgotten.
Digital Concepts 318AF http://go.magik.ly/ml/a3ba/ --out of stock, should redirect to a newer and/or similar model.
