The Digital Holiday Market was a success! The portrait plotter performed nicely and was well received. Many fascinated visitors and 7 plots sold in 3 hours.

Technical insights from this iteration:

• Horizontally centering your face is difficult because there is no clear indication of the right edge in the live preview. Many portraits turn out off-center without the subject initially noticing. Maybe add a gray line down the center of the screen.
• The drawings generally turn out lighter (more densely stroked) in the midtones than the prototypes. Some gamma tweaking may be in order.
• The silver Edding 1200 pen ran out in the middle of the evening (I had spares), after maybe 10 plots in total. I was expecting them to last longer, but they are inexpensive so that’s okay. Might try reviving it with some water, if I can get it open without too much damage.
• I may need a landscape mode for couples.
