Russ, How would you shoot fast paced action when you may not have time to FV lock w TTL?
This weekend I shot a wedding. During the reception and reception dancing I found it too difficult to FV lock w TTL. I used manual mode I wanted to control iso, aperture and shutter speed. I found TTL-BL to be more accurate, likely because my subject was sometimes near edge of frame. Other than dance floor the reception was very dark and to balance ambient light I would have needed excessively high iso's > 6400 w an aperture of 4.0 and shutter speeds of > 1/60 sec. I think now I understand why TTL would not work as well. The center weighted nature of TTL may not work for my subject matter.
Would you shoot TTL-BL in this situation even though ambient light was low? You are likely quicker w FV lock and other settings than me.
Some of my shots were hip shots w kids jumping or doing handstands and I had no time.
You can view some of these shots if interested in the K & R's wedding reception dance album in my Picasa link.
Do not judge the exposure entirely on what you see. Unfortunately I processed these on my laptop and noticed many underdeveloped. The angle I viewed my laptop while lying on the couch created an artificially bright screen. I have only corrected some of the images and need to correct all, prior to printing or presenting to the couple on CD. Many lessons to learn.
