From what I've read, carbon pencils give a more matte-like texture than graphite, and are a drier media - similar to charcoal. Graphite can become reflective when photographed and scanned so I'm surprised that carbon pencils aren't more popular.
Do carbon pencils need to be blended differently for a smooth gradation of tone (like willow charcoal does), or is it more similar to graphite shading?
Are carbon pencils messy, or can a precise line be achieved with it?
- Are there any disadvantages to drawing with Carbon instead of Graphite?
If it's not too much trouble, imagery for comparison is very welcome!
