Complete wedding galleries
Of course it makes very good sense to see a few complete galleries. It is important to know that your photographer will be able to consistently deliver the level of photography shown on the website and during the consultation.
There are also too many unfortunate cases where photographers fraudulently showed the work of others as their own. Also, multi-shooter studios often show the work of other photographers.
With that, I always recommend that couples ask to see complete galleries as representative work.
