|I use a brown lead pencil|
|Just sketch light relating each form and proportion|
|I don't really layout, just imagine where things will fall.|
|I was standing for 3 hours on the same spot.|
|I used both pages for a long panoramic in this case|
|You can get clues of where lines start and end by relating to forms you have already created.|
|Background penciling has the lightest tone.|
|It's important for me to have warm underwash for a glow later, especially for shadows.|
|Since I used yellow, I then used it complimentary color - purple to have this balance temperature.|
|I then start to color materials after the two pigment washes.|
|Start shaping the plant more vividly.|
|Contrast the little areas to differentiate of planes with more darker blues or purples for the final.|
Sketching on location has trained me to better see things than photograph referenced illustrating. The time to finish is actually shorter, more vivid, and you see everything that your eyes can see. Nothing can substitute that. Sometimes a picture, since it's tiny when printed cannot "capture" certain details or perhaps your eyes cannot fully pick up those details properly. On location eliminates this problem.
The point of sketching on location is the process of your eyes and your mind relates to the place being observed. It's not all about it being picture like or else you just use your camera within seconds and you move on to other places. The very idea is to take in the place's very essence of one's perception. The marks on the sketchbook to accommodate this process is the evidence, the product. The quality can be of your level, of course. It's not a question of how artistic it is.
Machines can never compensate for better perception and understanding of things, people and places. Sketching help us to better think, see and feel. Don't get me wrong. I love using digital cameras, and computers. I love the fact that they have changed the world by defying time and space. Bringing people closer and sharing our worlds instantaneously. No doubt.
