I am not a photographer so I thought I might ask the experts here

We are currently planning our wedding in East Europe (Slovakia).

One of our tasks is to find a photographer. We have received a few recommendations. The price is roughly the same, some are even 200 Euros cheaper.

I wonder what are some of the tips people look for. For example the photographer below. To me it looks fairly normal and not that special in quality or scene setting, but what do I know?

My second little question is, we also thought of hiring somebody who does the filming. Is that worth it in general? Somehow thought that watching a film in years to come in addition to photos

Thanks for your input
