This is a link to the CBS Sunday Morning item on Dr. Nathan Singer and his Botanical Photo Images They are awesome.
Paul, Thank you for posting. I heard about the photos and missed the show. They are awesome.
Dr. Singer paid/pays for all of this out of his pocket. Well above $500K.
He says his retirement monies have all been spent, with his wife's blessings.
Doing what you love to do is priceless.
