Me

My name is David and I currently live in Utrecht, The Netherlands. My professional background is in electronic system design.

I have been an amateur photographer since childhood, not only excited by the magic of photography but also interested in its technical aspects. I find it a challenge to devise and to experiment with simple aids that help achieve better results, trying not to forget that the best photographic aids are undoubtedly persistence and patience.

Photographic interest:

Insect macro photography and Travel photography
