I feel like I need to give some explanation.
I was with my daughter in the park with the kids from her nursury. All they were playing and running around.
I saw four of them running away and I didn't think at that time that this would be a nice shot. I took it in colour.
Later at home at PC (reviewing what I got) I saw this picture and the first thought that came to my mind was MONO! :) Here go the result!
Thank you all for your comments. Most appreciated!
