Michael Autumn talk about making "Golden Plover with Egg (Art Puzzle) - Laser" original artist print 

Beginning with a brief description of what the artwork is about, I go into detail about the making of this piece - and how the four tones of "colour" ("golds", blacks, whites, and off-whites) are achieved with just the power of a laser on pale wood (no pigments).
