Taking a digital picture and turning it into a completely different masterpiece is so easy to do with a photo editor like Corel's Paintshop Pro. The picture above started out being a color photo full of yellows and greens.
There are a wide variety of effects built into Paintshop Pro. This one is the standard black and white; I moved the contrast up a bit to make the individual foreground flowers pop out.
Consider using a bit of black and white for a touch of something spectacular on your site.
