The name of his shop is Club Fesch/Romance Sneakers. I walked past it in my last visit to Ajaccio, but it was closed. I found this video he made of it.

A couple of years ago he came out with a video called something like Yogacalifornia which was about that beach area at Little Capo, near the Blood Islands. I thought he did a good job with that and with that and another video, I liked his taste in music. I wonder if he's taken any courses in photography? I'm sure his dad gives him some tips, but it seems like Jo focuses (no pun intended) more on photographs, than videos.
Edit:
Looking at the video CleverCowboy posted a link for and another one done by Johann, I have to say they look professionally done. When you get married, you don't turn the job of filming the video over to anyone, not even the brother of a beautiful singer like Alizée, just because of who they are related to. It's a life time memory, so you choose someone who knows what they are doing and I have to think that Johann knew very well what he was doing and the videos he made were ones I would love to have if I were in that positions in my next life (Lord knows it's too late for this life!) So I have to think, he did have some training in this area.
