Hi abcd2hk, thanks for your comment. I can confirm that this is 100% real as I'm the owner of this photo :) The depth of field varies depending on many factors, it would be graceful to share the technique with you if you want to know more and you can correct me if I'm wrong, happy shooting ;) Dear all, thanks for your compliments. I love photography, I love the ecology world, it is so happy that I can put them together ^^
