3) Happy Photo
4) This photo of hot air balloons struck me as happy for a few reasons. First, the light is bright and crisp, it’s probably a great day for flying balloons. The sunlight is lighting up the whole valley and mountainside illuminating many verdant shades of green. It seems like a warm sunny morning where people are outside working or playing. The light is brightly reflecting off of each of the balloons showing all their rich colors. I think hot air balloons themselves create a whimsical and light-hearted mood that everyone can feel. Seeing a hot air balloon, slowly drifting through the sky, is enough to make me smile. The playful colors and idea of languidly watching the passing countryside makes me happy.
