Thank you very, very, much, Bridget for your RSS subscription that saved this post.
I had the opportunity to shoot another wedding the 2nd weekend in June, as many of you know and have been anticipating. There is not much that I would add except I would love to hear feedback on them, as always…
Yours truly, sparing no effort to get the dynamic picture…

Now, for a bit of how-to. The way I shot most of the group shots inside the church was this:
I set up my Vivtar 285v (gn of 47 or so) on my tripod off to my left, as you can see. I set it to the manual power setting of 1/2, since I obviously can’t use E-TTL. Then I bounced it off of the ceiling for a nice soft, yet off-camera-axis light. I then set the camera to expose manually, because the flash is an independent light source, like the sun or an incandescent light bulb. The only difference is that the camera can’t meter for it. Thus, fully manual exposure. To get exposure close I simple shot and tweaked the f/stop until I liked what I saw. Then I didn’t have to worry about anything except setting up the people and churning ‘em through.
Okay, so this is close to a full stop over-exposed. Inexcusable. But this does work in theory.
This one is a bit closer to correct exposure, after some adjustments.
An interesting note, I used a borrowed 20D, 70-200L 2.8, and a 50 1.4, besides my own XT and Tamron 17-50 2.8.
