When you arrive at the paint-out you are faced with a wide shot. Although we live in a 360-degree world, our intake is roughly 45-degrees, the average TV camera sees only 7-degrees of this world. Mentally you start choosing your own angle of visual acceptance:
nor a reporter of fact - no, you adjust your rendering of the scene so that it has a center of interest and some color surprise. You rule.
Start with a large brush, paint the main shapes of the scene - in this case simply paint the sky, the trees and the water. You're almost done in a matter of a few minutes this way. Change to smaller brushes, add the farm buildings and the yellow trees, include some water reeds...in other words, add TEXTURE to the large shapes.
Narrow your scene with your eyes (just zoom in mentally)
That's how I do plein air, yet it's like golf or tennis - occasionally you play well but you CAN have an off day. Donna worree, then come back another day. Every new start teaches the artist something. Its the only game in town.
