I always use flash for the processional, typically shooting f4-5. I'm also using one-shot which gives me some confirmation that I've achieved focus.
I see so many really beautiful natural light shots coming up the aisle and would like to do it as well, but have a few questions:
How slow a shutter speed can you safely work at to assure no motion blur; 1/60?
I assume you're using AI Servo?
Is there a max aperature you'll allow yourself for these shots?
Thanks for any and all insights.
