Images scanned directly from pencil and ink sketches. For the most part this is how my digital artwork starts out, just as an idea/doodle/character which might be inked over and then scanned into Photoshop. I have used various tools over the years but tend to stick to Windsor & Newton sketchbooks now, they’re not too expensive and the paper is great for any media, especially inking. I also have to mention Derwent Onyx pencils. I took a shine to these straight away after trying them. Not as dark as advertised but they hold a point well and have a very smooth feel to draw with.
