This is a quick guide for digitizing pencil or ink drawings using a phone camera and GIMP. The goal is to produce a clean greyscale (or transparent) image from a hand-drawn original, suitable for printing or digital use.
1. Capture the Drawing
Use a phone to capture a photo of the drawing on a flat surface. Position the phone at least 18 inches above the drawing, with the camera lens centered over it and the phone perpendicular to the surface.
