Pencil vs. Camera is project by Belgian painter, illustrator, caricaturist and photographer Ben Heine, in which he draws part of a scene, usually in a fanciful interpretation of it, and then takes a photograph of the drawing held up against the original scene or photograph.
The drawing is usually on a ragged-edged, odd shaped piece of paper, creating a more interesting intersection between the photograph and drawing. In some cases he plays rather fast and loose with his rendition of the scene, in others, his drawing is quite faithful.
