Question:

Do all digital cameras come with a black and white switchable feature?

Best Answer - Chosen by Asker: The best way to convert color to B&W is to use the Channel Mixer in Photoshop, which lets you simulate B&W film photos taken with just about any color filter.

Even if your camera has a B&W feature, you will get much better results if you always shoot in color and use your computer to convert the photo to B&W. Your computer has a much more powerful processor than your camera.
