If you have PhotoShop open the image and adjust the brightness & contrast (or adjust the levels if you want more control) you can bring a light line-drawing to life with this handy feature. If you don't have PS most scanner programs will let you adjust this.I drew a Sarr pitcher today, but I drew it so lightly that it's hard to see in the picture. I'll try to edit it and make it darker or something.
:O Very nice Is it....S. leuco?
