"SB 900 and bounce flash"



I have an SB 900 and a D7000 and my flash pictures started out pretty good but recently my bounce flash picture have been exposed pretty inconsistently. When I reread the SB 900 manual on page D-27 I noticed it says the camera must be in A or M modes and I had started using S mode. Sure enough that seems to have been my problem but I was wondering if anyone had any ideas why the S mode is a problem. I'm just trying to understand a little bit more how everything works and was curious about this.

>ideas why the S mode is a problem.

Because in S mode the camera controls the aperture.

Exposure for flash photography is affected by aperture, subject distance, flash power and ISO. So when using bounce flash your flash could easily be at full output (or close to it) and a small change in aperture can easily cause exposure issues. Being the camera is choosing the aperture, you might not notice how much it is being stopped down.

Tinker: further to what Pete has mentioned I'll add a link at the end of this reply. There's a website by a fellow named Neil Van Niekirk who is a wedding photographer. His free site will explain the use of a single flash either on or off camera. His approach while using flash is to make it look like was flash wasn't used. He also has a couple of books which are worth the price. Here's the link http://neilvn.com/tangents/ Richard

Another thing to watch out for when shooting indoors is to make sure you are using regular TTL and NOT TTL-BL. TTL-BL is for balancing the flash with bright ambient conditions. Regular TTL will fully expose the subject, which is what you want indoors.
