Query: Incredible!!!

I just recently listened to the author present a photography lecture at my state photography convention and was so inspired that I bought his books. All of the Amherst Media books (I have several) are fairly short and easy to read. The work that the author has done with digital infrared in just amazing! The images are so cool and it looks so easy. I had always been intimidated by infrared photography, but having read this book I know that I will be able to get great pictures. This is a must have book for anybody looking to venture into the creative realm of invisible light.
