I also use my sketchbook to record thoughts about paintings that I have; I find it's better to get them down when I have them, rather than try and remember them later. Try as I might, I never remember everything!
Looking at the Santa Maria della Salute at night got me thinking about painting a night-time cityscape. What would be the best format -- landscape or portrait? Where would I position the horizon, high up so there was plenty of reflected light in water, or low down so there would be lots of dark sky?
(See the next page to find out which painting I did first, when I got back home.)
