Not posted for a while as been on a Plein-air painting event in Norfolk organised by Linda Matthews. A great event and I learnt a lot. I benefited from painting 8 hours a day for four days and from observing some really great painters such as http://www.valeriepirlot.com. The main things I took away were to raise the tones and contrasts to compensate for indoor vs outdoor lighting, and to check for fundamental problems with compositions, especially awkward diagonals. Some of my paintings from Norfolk below.
The Norfolk Broads are a great place to paint with a possible painting around most corners. To me the most interesting objects were not the windmills but the massive oaks standing out against the stubble fields.
