Thanks, but I was not the photographer and these were just two grab
shots to see what ISO 3200 and a single flash could do in this large
church. But I did photograph the groom and his groomsmen getting ready
for the wedding and I also put the church lighting lesson to work later
that night. The same bounce technique worked pretty well in the
reception hall with its 12-15 foot ceiling at ISO 1600. Previously, I
wouldn't have tried that without some external studio strobes bouncing
off the ceiling and lighting a larger area.
