I met Jeff at China Open and interviewed him
Debstah you are right, they are an old couple. Both already retired and now they take tennis pics mainly because they are interested in it.
Manuela has been a photographer for a long time, while Jeff took up photographing about serveral years ago (after he retired).
They go to some nearby tournaments, and some big tournaments. Sometimes they are invited to go to other tournaments too. Jeff was invited by somebody from the Luxion company (they're good friends) to China Open. He has never been here so he was quite excited. He said the people of China were much more interesting than the tennis matches, lol, he took tons of pics at Beijing.
BTW Jeff uses DSLR.
