His assistant speaks English well, he doesn't. If you want a lot of posed photographs, he's probably not who you want. I wanted a lot of candid shots so it worked out well for me. I just emailed him prior to with a list of the shots I wanted (getting in the dress, the kiss, family shots) and things I did not want (a pic of every groomsman and bridesmaid together, the groomsmen holding the bride sideways, everyone jumping on the beach, etc.). The biggest disappointment for me, was that he didn't get the guys getting ready but that was not his fault. It was partially mine since we had a room so far away and partially the groom b/c he didn't wait for Valeria's assistant to pick them up as we discussed in the meeting. (it freaks you out a bit when your WC calls you in a panic b/c she can't find your groom, I think she thought she was breaking the news to me that my groom was ditching me, fortunately my Dad had seen them make their way to the chapel) But that is neither here nor there.
It was sort of a risk getting him as he had only done 1 wedding prior to mine. He has done several other wedding since and his work seems to be getting better each time. I loved his work. The only other thing is that I would have said fewer during the ceremony (it was a full catholic wedding so there are a lot of chapel shots) and more during the reception.
Let me know if you have any questions!
