Roland Garros is really okay, nothing to complain about regarding that department!
The camerawork is good, the producers are very very refreshingly playful which you can see in the great, sometimes funny graphics and several other effects (fadings, mirror effects, posterization. solarization and other tricks four:love for example showed in the post above...) before the player serves, when showing replays or during changeovers.
Another tournament which is excellently produced IMO is Kitzbühel by ORF (Austrian television). I noticed this especially since the last two years and the producers and directors seem to be very capable there. Good coverage, good camera positioning, well directed and usually a good commentator team (with Alex Antonitsch), only the oncourt reporter sucks a bit and I don't like him.
