A few days ago, I purchased the Nikon SB900 flash for my camera! I always knew I had to buy one someday for my career.... but for some reason, I kept putting it off! We had a lecture last week in our photojournalism class about fill flash and it inspired to buy one! I was kind of on the fence about which one to buy... so I contacted a classmate of mine, Trent Chau, because I knew he had some knowledge about flash. Thank you Trent for talking me through this!! I was trying to decide between the SB900 and the SB600.... the 600 is less expensive than the 900 and of course being a student, I wanted to go the cheaper route! But I thought about it... did some research.. and was convinced to get the 900! So worth it!!
