The type of pencils an artist uses can vary widely depending on their style and the desired outcome of the artwork.
- **H pencils** (hard) are typically used for fine lines and lighter shading. They produce a lighter mark and are good for detailed work.
- **B pencils** (soft) are used for darker lines and shading, allowing for richer tones and more expressive strokes.
- **F pencils** are somewhat of a middle ground, but they are less commonly referenced compared to H and B.
- If the artwork is entirely in ink, then none of the pencil options would be applicable.
Without visual context or more information about the artwork, it's difficult to determine which pencils were most likely used. However, if the artwork involves detailed line work and subtle shading, it might lean more towards H pencils, while if it is more expressive or has rich shading, it might lean towards B pencils.
If you provide more context or specific details about the artwork, I might be able to give a more informed suggestion!
