A Whole New Meaning of Color

I've seen a few friends of mine who are very interested in photography post pictures where the entire picture is grey scale except for one part of the picture still has color in it. I've always thought how cool this looked and always wondered how they did it. In class today we finally learned how to do it and I was very excited! It is amazing to see how you can add such emotion to a picture by concentrating on certain parts through color. I'm hoping to apply this to my upcoming project. I may make a young child's eyes be the only color showing as a sign of hope and to have an emotional appeal of people walking by, or just have the color of the gun showing to represent the violence that is going on there. Either way, color can add so much more meaning and emotion to a picture than one would think.
