If you are planning an event, why should you have to find a videographer and photographer from separate companies? After all, the videography and photography for an event should be integrated and seamless. It's hardly optimal for the videographer and photographer to meet for the first time on the day of the event. Neither should you, the client, need to negotiate the packages (and personalities) offered by separate event photography and videography businesses.
Why not hire one company to handle all your imaging needs on the day of the event?
Event Horizon is just such an alternative.
