Today I was going through a book, "Photo Inspiration: Secrets Behind Stunning Images" (published by John Wiley & Sons), showcasing various photographers, their works and, most importantly, brief descriptions on how each photo was accomplished.

Under the Chapter, "Editing," a layered one was shown which looked very similar in technique to the dog photos. The photographer, Kiyo Murakami, explained that she (?) photographed the her model surrounded with autumn leaves suspended with invisible thread (available at sewing stores), took several other photos of out-of-focus lights and dark trees, and layered the lot for the final photo.

I am not re-posting the photo here for copyright reasons.

Just before that, I Google'd bokeh images thinking that was how the dog photos were done. Came across at least one, some Monarch-like butterflies on twine, that was definitely layered into one of the dog photos. (see her Flickr site)

It is fun trying to figure out how a photo image has been created. Have filed this one away for future possibilities.
