Editing a picture so only one color shows...?

Question

I see people that have pictures posted on their sites with, for instance, only blues objects in color... how do I do this with my own photos?

Answer 1

You need an image editing program that can work with individual color channels. Photoshop is the one that most experts use, but Paint.NET is a freeware alternative that supports most of the same functions (see the link below). You'll have to play around with it a bit and read the help file to figure out how to use it, otherwise put the photo on flickr or something and ask someone here to do it for you.
