I recently purchased an SB-28 to go with an N90s. My question is this. How does one go about figuring exposure when bouncing the flash of the ceiling? Thus far I have been very happy the flash and letting it (the flash) handle determining power output level. Question # 2, what mode do most of you use with the flash. I Still find myself using aperture priority most of the time. Any thoughts or experience you all my have would be greatly appreciated. Thanks Logan
