Moments after the exchange of vows, Eric and Abby seem oblivious to the appreciative audience sharing their special moment.Those who have been using a DSLR for more than 6 years might have some sense of why shooting with an ISO set to 2000 and getting fairly clean result is worth commenting on. I rarely shoot at higher than 400, but in this particular church, that isn't an option for available light photography. And you will note that even at ISO 2000 and with an aperture of 2.8, I am still using a shutter speed that risks blur.When I am shooting with a slow shutter speed, I look for moments when the action slows down. In this case, the only blurred object that I can see is Abby's earring.Canon 5DII 1/50s f/2.8 ISO2000 200mmColor Version (click)
