    Sometimes the best shots happen when you least expect them. Jorge Uribe noticed the striking contrast between an iconic Barcelona building and the sky and captured this incredible #PhotoOfTheMonth. "I stumbled upon this iconic building designed by architect Toyoo Itō in sunny Barcelona on a beautiful cloudy day, and it felt like the perfect fit for CoStar Group’s RED photography contest. The red accents on the facade really popped against the moody sky, and I couldn’t resist capturing it. After a bit of editing, the final shot turned out just as I envisioned. It was one of those moments that turned out great when you least expect it! Having my work selected is a huge honor, and I’m truly grateful for the recognition," says Jorge. Congratulations, Jorge! Thank you for capturing beautiful shots like this for our clients.
