PENCE GALLERY. In this introductory class with artist Linda Clark Johnson, you’ll learn all the basics of making beautiful blue cyanotypes, a fun and easy alternative photographic technique. Using light-sensitive chemicals, you’ll expose prints of plants in the sun and process them in water. By the time you leave, you’ll have 4 gorgeous 8 x 10” blueprints and the know-how to create more at home. Register at pencegallery.org. 10a—2p. $115—125
