I think that you can probably turn some of those shots into “fairytale” type captures with proper editing, Mark.
Put up a couple of pixs that you think are candidates and maybe we can help?
I often edit my shots as a guest and typically have been told that my shots are superior to the ones taken by the official, paid-for photographer.
Does the couple have at least TIFFs of the wedding from the hired photographer? If so, then editing would not be a problem.
