As Hugh is saying, there's a big difference between shooting models in FAB locations with a tutor and having to shoot someone uncomfortable in front of a camera, in a poor location who may not be fantastic looking either
Wedding Photography training to me should be about the whole shoot for the whole day, but most seem to focus purely on the B&G set, and then use OCF and other lighting techniques to wow you into buying those courses
Shooting a Wedding is simply a series of skills and shooting types all needed on the same day - for instance, mine often start with...
- Still Life - the dress, shoes, tiara etc.
- Then documentary style of the prep, usually with no added lighting
- Then a Bridal portraiture session
- Followed by a hint of macro and male portraiture and male group fun
- Back to documentary to arrival and ceremony
- Then a posed mini group for the signing
- and so it goes on
You need a whole range of skills, and I've not seen a course that actually teaches them as used in a Wedding
Its tricky and no doubt
As for the B&G bit, yep I spent a day with Brett and learnt a few bits; Pete Bristo's day can be useful too
Whatever you do I think it more important to do several days with a variety of trainers and pick what bits you like, spending everything with one training group is likely to make you another version of them at best
