Who said anything about moving them?your not going to be running around with speakers every 5mins because its in a shot.
They should be correctly placed to begin with.
There is NO REASON the speakers need to be placed in a manner which makes them stick out like a sore thumb during the ceremony.
And this isn't just about the pictures. Or the photographer's pictures.
What about the guests? Here they are, sitting in this beautiful location, facing forward, looking at the bridal party, and they can't accomplish that without the DJ or DJ's gear getting in the way? WTF?
If live musicians can figure out how to be heard and not seen, why can't DJs?
