Canon 5DM3, Canon 70-200mm@121, f4@22, 2.5s, ISO 100. PP: PSCC - adjusted Temp & Tint, exp -.65, increased contrast, clarity and vibrance, darkened sky c Gradfilter, slight LCE, and sharpened with PKS 80% opacity.
Photo taken this may on a workshop with Hans Kruse in San Quirico d'Orcia near Siena, Italy. I went with f22 in an effort to get the yellow flowers in focus, but because they were blowing in the wind, f9 or so would have been a better choice.
