As the Hertzberg Intern, I am currently working on 217 architectural plans and drawings from the floods last summer. The first step was to identify the different types of plans so I can research how to treat them.
Can you match the names below with the pre-treatment photos?
A. Blueprint or Cyanotype
B. Tracing Paper
C. Negative Vandyke Print
D. Blue Diazotype
E. Sepia Diazo Print
Good luck. I’ll post the answers on Thursday.
