I found myself without a pencil (again) today. I like drawing with a pen these days. It is much less forgiving than drawing with an erasable implement but the pen shows each and every stroke. The collection of slashes and strokes give the resulting sketch directness. The ‘post production’ phase of a pencil drawing may involve erasing lines or increasing the range of tonal values by emphasizing or reducing existing shading.
In the Waiting Room below, post production consisted of using alcohol markers to emphasize planes and to add color.
