Heartless

The photo caught my attention at first glance and honestly, I didn't realize that this is purely a photograph, the heart is formed completely by adjusting lighting and depth of field.
The concept of this image isn't new and the author even said that. However, I was really fond of the photo, probably due to my lack of knowledge about the concept (that a heart could be made from a circular object) and my own reference when I saw the photo.
This image gave me a a sad feeling. The light was cold and there is a lonely ring, forming a heart. I thought this could be the feeling of someone who is abandoned, left with a ring of memory and continues remembering his/her love.
