"Photo of the phenomenon of the shadow of Doi Suthep Temple above Chiang Mai city last night (July 3, 2024). Why do we see the "Shadow of Doi Suthep Temple" floating above Chiang Mai city? Many people might think it's a rare phenomenon, but it's actually explainable by the scientific principle of shadow formation, which requires three key elements: a light source, an object, and a screen.
Light source: The shadow isn't caused by sunlight, but by the spotlight installed at the corner of the temple, turned on twice a day (7-8:30 PM and 4:30-5:30 AM). The directional light creates a clear shadow.
Object: The temple acts as the object blocking the light, casting a shadow in the opposite direction.
Screen: The crucial element is the low cloud layer acting as a natural screen. If the cloud is in the right position, the shadow is projected onto it, making it visible.
The visibility depends on the observer's position, light direction, and cloud conditions. This phenomenon is common during the rainy season, especially after 2-3 days of continuous rain, as low clouds often cover Doi Suthep, creating a perfect natural screen.
The perfection of the shadow depends on the cloud's characteristics, position, and movement. Nature and science combine to create a breathtaking sight. If conditions are right, look up and you might spot this rare shadow of Doi Suthep Temple.
Photo equipment: Nikon D750 + 24-70mm f/2.8 lens, tripod. Technique: Long exposure (10sec), f/2.8, ISO 100, WB 4500K."
