Flashes are rated in their "guide number", which equals the distance (in feet) times the f-stop at ISO 100. (Guide numbers are also reported for meters, for the rest of the world...). If you want more flash range, then you either want a wider aperture, or a higher film speed.


Nope. You lost me at "f-stop". Where's a good site for finding out what all this camera jargon means? I thought about buying a D-SLR for taking on honeymoon, but figured, since I didn't know how to use it, that I might as well stick with my Ixus 400.
