There are many different techniques and ways of creating a selective color images in Photoshop, let me show you the one where we use the black & white adjustment layer.
If you don't want others to use your photos and images without your permission, you can create a so called custom watermark with your name or any other text you want.
Pretty cool Photoshop tutorial, where we will add two text layers, one will be placed behind and the main at front. And I think you might really enjoy the final result, go for it and have fun!
