Pen and Ink is my choice for architectural renderings. I use archival, water proof ink that doesn’t fade over time. The hard, dark edges are perfect for rendering houses and buildings in detail. My pen and inks are finished fully in black and white. Once that’s done, the piece can be taken to another level by adding color. I usually do this with watercolor, tinting areas of the artwork while letting the ink drawing under neither create the shadow effects.
