I was actually on assignment for the former America West airlines when I was shooting this guys cornfield. He drove up and asked what I was up to. We chatted and later became friends and I was invited to photograph anytime I wanted including wheat harvest where we set up this photo.
It was shot before sunset so it had the golden light of the setting sun. Having them in the foreground with the combine in back added a great sense of depth. It has been on brochure covers, bank ads, and more.
