Hi all, I'm asked to help take photos for my friend's ROM ceremony, I intend to get a SB800 for my D70. Just wondering, besides the speedlite, do I need a diffuser as well ? or can simply bounce the flash off the ceiling.
Also, how to calculate how far can the SB800 cover? I think I saw a formula in one of the website before but lost the URL already. Wanna know what's the difference in range between the SB600 and SB800.
