So I went to Michael's yesterday and was just wondering how much it will cost to buy a flash for my D90 and the benefit of using one.
The guy told me that the main reason people get a flash is so that the camera battery will not be drained fast when using the in built flash.
and when I asked about the quality of the picture being different from using the in built flash (being more harsh) and a flash unit (more natural looking), he told me that all flash will be harsh.
Is this true? and can anyone explain to me other benefits of using a flash unit? and is SB-600 or SB-900 the way to go?
Thank you in advance
