A Day Not Wasted, an Artists Challenge site with wonderful photos. He is also a painter.
It was interesting to do something architectural, and with watercolor. In looking at the cast shadow as well as shading in the photo, it seemed the best medium to use to get the transparent washes for the cast shadows especially. In reality it was much darker, but in using pan watercolor it didn't go as dark as the original. It was also 140lb paper, and it was getting pretty wet, doing a lot of wet into wet painting.
This is using the new 4X10 inch Arches block. Interesting dimensions, sort of a "slice" view of things. I like it and the new 8X8, which fits in my watercolor bag that lives in the car.
In this picture the perspective got a little off in the farthest corridor, I kept losing track of the bottoms of the columns and the reflections! It was a highly polished floor.
All those rectangles helped with keeping the perspective in hand, the arched vaults and lintels were a different kind of challenge. (I think I need to buy some tracing paper.)
