Don't often
what with flash?
Flash can do wonders indoors (obviously) but can also help alot outdoors when dealing with harsh shadows or uneven lighting on subjects/backgrounds.
I have the 540, because I needed the extra power and it swivels. There is no way to do a ceiling bounce with a vertical shot with the 360 (unless you get the flash off the hotshoe somehow)
Yeah, I recommend you learn to "love the flash" especially since you already have a decent flash unit.
Originally posted by jgredline I do have an external show mount flash (the 360) but since I don't often with flash, I hardly ever use it..
