We had a wonderful tour with Vianney in London. Vianney's love of photography comes through as soon as you meet him. He is an excellent teacher and is very patient. I learned more in a few hours with him than I could ever have learned on my own. I was able to also get some wonderful shots of London after dark and apply my new knowledge at other locations. I would highly recommend Aperture tours and Vianney to anyone looking to improve their skills and to get some excellent photos.
