Using ImageMagick to convert images to grayscale

Although color images are nice, I try to avoid using them in articles, as that always costs extra. Sometimes I also prefer grayscale images for presentations, since the colors of the projector can often be quite different from what I see on my screen.

Anyway, here is a simple way to convert an image from color to grayscale using the command line tool ImageMagick:

convert inputFile -colorspace Gray outputFile
