So far I have only been using my pretty average phone's camera to get my drawings uploaded. I wasn't aware I could get those kind of results from changing the contrast settings in the camera, I'm definitely going to try it! I do use Online image editor pixlr free - fix photos direct in your browser to edit things after I'm done. Eventually I will be buying a scanner and some real software, that is when I will also start trying my hand using line art to convert to digital graphic/art soon :3 I still have much to learn so thank you very much for the tip!
