Here is the example I brought to my classes. I took this photo in Corneglia, Italy a few years ago.
I loved the light coming through the arch and spilling down the stairs, the window leading to nowhere, and the textures are great. However, the camera lense distorted the angles of the walls and windows. Can you imagine how wrong my painting would have been had I just traced this photo and painted it?
My painting below captures the light spilling down the stairs, the window to nowhere and the textures I found inspiring. But my creativity let loose in the colors I chose making the painting definately not an exact copy of the source photo.
