Upon arriving in Venice early in the morning after a dreamlike sunrise flight over the snowy Alps, we opened the window shutters in our hotel room and saw this jumbled and delightful view of rooftops--a kind of back view of Venice. It appeared to be a complex subject to draw, but recently I discovered a book on sketching architecture, Freehand Sketching: An Introduction, by Paul Laseau, with some excellent exercises and insights. Laseau writes that while perspective is a handy device to construct imagined spaces, it is not useful, and possibly detrimental, to sketching existing environments. Using perspective can place an arbitrary screen between you and the environment, leading to rationalizing rather than scrutinizing your subject. I used the book with the classes I taught this winter on travel journals. To sketch freehand, it's important to create the frame first and then fit the larger elements into the frame. In this sketch, I fitted the roof in the left foreground in first, then the wall above it, adding the outside contours of each of the large shapes. Once those are in place, it's easy to subdivide those spaces by adding windows, arches, chimneys and
moldings. The paper I used is made by the Ruscombe Paper Mill in England. They make a variety of very traditional toned watercolor papers--this warm creamy brown with the lovely texture of small hemp fibers floating here and there is called the David Cox paper, after the famous 19th century watercolor landscape artist. They also make Turner blue, a stunning gray'green/blue hue. All of these toned papers are relatively smooth and allow for precise line work. I stretched this piece first on gator board, as it's rather thin and would buckle under heavy washes, though I think it would work fine for pen and light wash without stretching.
In Step 1 you can see how I began, as I left some areas unpainted.
In Step 2, more areas are painted, but there are still many details left to add.
In Step 3, you can see completed tiles, and a light glaze of cobalt blue over some of the shadowed areas.
In Step 4, the completed sketch, also shown above, notice how I have painted white on some of the tiles and molding. Those highlights help to show the sunlight striking some areas. And in using toned papers, the addition of white gouache really completes the painting or sketch. The 19th century British watercolorists used it frequently. I opened a fresh tube of Winsor and Newton Permanent White Gouache, and at nearly full strength it really covers.
