When shooting indoor, low light, high ceilings, no close walls, or out side at night, I want to use my flash head on. The 430EX has a diffuser built in (intended for wide angle shots), but is this enough diffusion in gnereral? I have an Xti, so I hate to increase ISO to its limit. Is there another diffuser for these situations that I should be looking at or is the built-in one about as good as I can do?
Thanks.
