I've enjoyed putting some of my pictures into sepia ... and keeping part of the picture in colour. To do this you need to work with your layers, and make the top sepia layer into a layer mask - then "paint" with black where you want the colour to come through from the other layer. This is how to do it but I realize these directions are very simplified. You have to be careful to only get the part you want in colour. It takes some practice, but is effective with some pictures.

God provides a much more colourful world for us than sepia. He paints this world in a riot of colours for our enjoyment. I'm glad we get to see in colour. Too often we're too busy to appreciate this though. We need to take time to look around us and enjoy what God has created.
I am come that they might have life, and that they might have it more abundantly.
