I see the non-photo blue pencils in the pencil section all the time, and I'm wondering what their purpose is for modern artists.
Do I need one if I want to scan in drawings where I've sketched the underlying framework? Or can I just use any color that's not my final color and use my digital art program to remove it?
With modern scanners, cameras and digital editors, do I still need to have a non-photo blue pencil in my artist's armory?
If you're curious, I would just buy one of these pencils and play around to see if you like it. You can get a single one to try out for $2-3.
