These are Asiatic Lilies and extreme closeups. I find the abstract quality of the images most interesting.
Here is another selection of floral/botanical images in black and white. Black and white photography is the art of exploring the interplay between light and shadow. These floral images provide great opportunities to do so. What is fascinating is that a slight change in one parameter or another can result in a completely different – yet still realistic – image when viewed in monochrome.
