Here is a watercolor of my hometown Lyon (or Lyons) made with FotoSketcher 2.70 (click on image to see in full size).
The original photo was taken by photographer Mouhamad BZOU http://www.facebook.com/m.bzou.photography.
Before you ask :) I'm sorry I did not save the exact parameters I used, but I remember that I first ran the Painting 5 effect, then pressed F12 (to use the resulting picture as a new source) and then I ran the Painting 1 effect with color blending set to a high value (e.g. 160) and strength of effect to a low value (e.g. 5).
With FotoSketcher, experimenting is key!
All the best,
