Gone are the days of the old 'blueprint' technology for Landscape Architecture. It was a nasty chemical process called Diazo Print. That process was created in the late 1800's using a chemical ammonia bath and a light sensitive paper. Sometimes this is called 'White Print' because the result is creating white lines on a blue paper. The original was drafted with pencil or pen on a sheet of translucent vellum so that light could be passed over the vellum and allow a contract onto the chemically reactive paper. Later we used computer drafted designs printed onto vellum for the same reproduction process. Originally, printing large sheet landscape designs from a computer was very expensive. It was done one plotting machines that moved actual pens around a large format table. Sot all that different than 3D printing today. And notoriously difficult to keep the pens in shape and operating correctly. Today large format printing is rather inexpensive and we simply print our large format landscape designs directly from large format laser printers. But in that, we lost some of the character of the old blue diazo prints, or the brown sepia versions. But we can recreate some of that quality and character with digital image manipulations. This one was done in Photoshop. It is a landscape design for a swimming pool, travertine patios, pool house, landscape plantings and outdoor lighting in Bucks County PA
