Inspired by world-renowned wedding videographers White In Revery, Declan became a full-time wedding videographer in 2017. With the ambition of moving couples with cinematic, emotive, and story-driven films, he visited Colorado to be mentored by White In Revery. Becoming a dual citizen enabled Declan to film hundreds of weddings across the United States and expand the business. As of 2024, Declan Cadman Films is based out of England, but maintains a wedding videography presence in the US.
