I contacted Randy in May about organising a Night Photography Tour for Paris in September. All the arrangements went extremely smoothly, and I had no difficulty in meeting up with my guide, David, on the night. He was friendly and good natured, and skilled in teaching the art of photography.
I had a good time, and learnt a great deal about my camera. There were, however, a couple of instances where I felt like David was more focused on setting up for the shot than on imparting insights and knowledge to me. (Perhaps we were rushed because I'd spent too long getting the shot elsewhere.) There were also a couple of occasions where I felt we'd spent enough time trying for one shot, and David was persistent with "one more". (Maybe patience is a characteristic that explains why he's the photographer and I'm just a keen amateur! ;) )
I applied some of the skills learnt on this evening with David on the rest of my trip, and my photos were so much better as a result of that experience. I was very pleased with the best of my photos on the night (though did note that they look very similar to shots taken by other people who've done this tour...)
I recommend Photo Tours in Paris, and would have no hesitation in booking a tour in another European city.
