I worked with David Zendlo, owner of Zendlo Photography at a wedding last fall. He was very kind and courteous, stayed out of the way, and did not cause a any problems.
His work was basic, traditional, covered all of the aspects of photos the couple wanted.
They were not very photo journalistic - not sure if that is what the Bride wanted or not, just commenting on it - not very artsy.
Very basic. He did provide a dvd to look at to choose prints from.
