RASTER GRAPHICS SOFTWARE (PHOTOSHOP)

Drawing shaded relief with Photoshop (or with another raster software application) rather than with traditional pencil or ink has the following advantages:

• The possibility of making multiple corrections to the same area.
• Every production step is "undoable".
• Simultaneously viewing multiple cartographic base layers (contour lines, the river network and other structure lines) with the shaded relief.
• Shorter production time.

Tom Patterson provided us with a short animation showing the process of relief shading with Photoshop.
