I just received very sad news that Sunny passed away at age of 67. He was a great photographer of butterflies and will be missed in our community. Although I met him only once on top of Doi Pui there will be no other chance to know him better anymore.
Really sad news, Antonio Giudici e-mailed me to let me know and I have just seen your post.
As well as a great butterfly photographer he was a really fantastic fun character, very kind and with lots of interesting things to talk about, a real loss to the community, especially in Singapore (his home) where he was one of the top butterfly experts.
