It may seem counter-intuitive, but the best monochrome photos aren't necessarily taken in black and white to begin with. If you want great black and white shots later, stick to colour while you're shooting. Anil Polat of foXnoMad explains why.

Anil takes a lot of photos on his journeys around the world, and while almost every camera has a black and white setting, he's noticed something almost universal about them. Taking your photos in black and white completely removes your freedom to adjust, tweak, and highlight certain areas of the image later. He suggests taking the photos in colour, and then using the freedom of an image editor later to make your monochrome shots gallery-worthy:
Many digital cameras have a black and white function that allows you to take the image directly in black and white. While this may seem convenient, I would suggest avoiding the temptation as it leaves you few options for creatively manipulating the image later. You are much better off using an image editing program and converting it from colour as you have much greater control over the final image.
