I am a member of Delaware Photographic Society. http://www.delawarephotographicsociety.org/\
This past Monday, Joe Rossbach was the guest speaker at the weekly meeting. He is a self taught nature & landscape photographer. I was at his lecture last year as well. I enjoy his work and appreciate the valuable information he shares. He is with the Mountain Trail Photo team. http://www.mountaintrailphoto.com/ That day, I purchased a book "The Ultimate Guide to Digital Nature Photography" put together by that team. It is pretty good; you will find awesome photographs along with some highly useful photography tips in it. I consider it to be a great addition to my library.
