Make Your Grays Colorful
Some images look very good in gray scale but don't think your conversion is done just because you clicked on "black & white". I use Adobe software, Lightroom mainly, and when I convert an image to gray scale I go immediately to the color sliders to refine the effect. You can increase or decrease the intensity of the colors in your image by moving the corresponding color slider. It can really change the "look" of your finished product.
