We only spent one day in Orvieto, but most of the day we spent sketching. We spent a couple of hours in the Duomo, had lunch, then sat on a back street cafe for our last sketch session.
Sketching enhances you trip in three ways –
First, it causes you to pause, to take the time in a place longer than it takes to snap a photo and move on.
Second, it makes you observe more fully. When you sit with pen or pencil on paper, you are forced to look at details you would have missed. How many panels are on the wall behind the altar. How tall are the stained glass windows. How are the shapes repeated throughout the installation.
Finally, and most obviously, it enhances your sketching skills. Just like anything, the more facility you have with an activity, the more enjoyment you’ll have.
